System To Produce Gaseous Hydrogen

Description

FIELD OF DISCLOSURE

The present disclosure relates to a system and method of producing and collecting hydrogen gas, and particularly a wiping device which removes impurities from the surface of a reactive metallic or semi-metal material to allow for collection of hydrogen gas by the system.

BACKGROUND OF THE DISCLOSURE

Hydrogen gas in by far the most plentiful element in the universe. Hydrogen is the ultimate power source, powering the massive stars that dot the vastness of space. Hydrogen is also an essential element for life; water (H₂O) makes up a large part of most living animals and organisms.

Though plentiful throughout the universe, hydrogen is not plentiful in its gaseous form here on earth. The majority of hydrogen that one encounters day to day is chemically bonded to oxygen in water. Breaking this bond and obtaining hydrogen in its elemental form allows for a multitude of uses, and elemental hydrogen is employed in many industries. Originally, because of its low density, hydrogen was the ideal choice for filling airships and balloons for travel and other endeavors. However because of hydrogen's extreme reactivity in the presence of oxygen, this practice largely came to an end in the late 1930's.

In the chemical industry, hydrogen is often used to make ammonia for agricultural fertilizer. Hydrogen is also used in the production of plastics and pharmaceuticals, and is an important element used in oil-refining processes. In the food industry, hydrogen can form hydrogenated oils from fats for uses in butter substitutes like margarine. In electronics, hydrogen provides an excellent flushing gas during the manufacture of silicon chips.

Perhaps of the greatest current interest, hydrogen has been described as the fuel of the future and this appears to be true. Producing energy with the use of hydrogen fuel cells, hydrogen leaves no harmful byproducts as it returns to water when it oxidizes. Similarly, the combustion of Hydrogen in an internal combustion engine leaves only water as a byproduct.

Although hydrogen has a multitude of consumer and industrial uses, it is still challenging to effectively and efficiently refine hydrogen. Known methods for producing hydrogen gas include steam reformation (e.g., with a hydrocarbon feed stock) and electrolysis. Steam reforming to produce hydrogen is the most popular method of hydrogen production. Steam reforming involves reacting steam (H₂O) with methane (CH₄) in an endothermic reaction to yield syngas, a fuel gas mixture consisting primarily of hydrogen, carbon monoxide, and some carbon dioxide.

As noted, an alternative process for generating gaseous hydrogen is referred to as electrolysis. During electrolysis, hydrogen is produced via an electric current in water. The current disassociates the hydrogen from oxygen to produce gaseous hydrogen. While reformation and electrolysis are frequently used, other methods of producing gaseous hydrogen are available as well.

While the present disclosure is directed to a system that can eliminate some of the shortcomings noted in this Background section, it should be appreciated that any such benefit is not a limitation on the scope of the disclosed principles, or of the attached claims, except to the extent expressly noted in the claims. Additionally, the discussion of technology in this Background section is reflective of the inventors' own observations, considerations, and thoughts, and is in no way intended to accurately catalog or comprehensively summarize the prior art. As such, the inventors expressly disclaim this section as admitted or assumed prior art with respect to the discussed details. Moreover, the identification herein of a desirable course of action reflects the inventors' own observations and ideas, and should not be assumed to indicate an art-recognized desirability.

DETAILED DESCRIPTION OF THE PRESENTLY PREFERRED EMBODIMENTS

FIG. 1 illustrates a schematic overview of a hydrogen generation and collection system in keeping with an embodiment of the described principles. A first containment vessel 10 is included into which additional elements are placed. The first containment vessel 10 has at least a top portion 12 and a bottom portion 14 in an embodiment, and takes any of a multitude of cross-sectional shapes including but not limited to a cylinder, square, rectangle, or triangle.

The bottom portion of the first containment vessel 14 is attached to the sides of the first containment vessel 16. The top portion of the first containment vessel 12 is, in this embodiment, either open or in contact with the sides of the first containment vessel 16. Additionally, the top portion of the first containment vessel 12 is fashioned from a covering device 18. This covering device 18 is a lid, cap, canopy or seal or the like placed on the top portion of the first containment vessel 12 and attached to the sides of the first containment vessel 16.

A solution of H₂O 20 is placed inside the first containment vessel 10 in an embodiment of the disclosed principles. This solution of H₂O 20 includes H₂O as well as a caustic. The caustic is any of a variety of caustic substances, and is introduced into the solution of H₂O 20 in either a liquid or solid form. If introduced in a solid form, the caustic has the ability to dissolve into the solution of H₂O 20 as to adequately disperse the caustic throughout the solution of H₂O 20. One caustic used is NaOH, however a variety of other caustics which react with the below described metallic or semi-metal material 30 can be used. The solution of H₂O 20 which is placed inside the first containment vessel 10 fills at least part of the interior of the first containment vessel 15.

Additionally inside the first containment vessel 10 a metallic or semi-metal material 30 is placed inside the interior of the first containment vessel 15. The metallic or semi-metal material 30 is placed inside the first containment vessel 10 in such a fashion so that the solution of H₂O 20 adequately covers the metallic of semi-metal material 30. The metallic or semi-metal material 30 is a material which chemically reacts with the solution of H₂O 20 to produce at least a hydrogen gas byproduct. Examples of such metallic or semi-metal materials 30 include but are not limited to aluminum, ferrosilicon, copper, iron, magnesium, and zinc.

A second containment vessel 40 is disposed remotely from the first containment vessel 10. The second containment vessel 40 is connected 42 to the first containment vessel 10 in such a fashion as to allow for the solution of H₂O 20 to freely flow between the two vessels. Such a connection 42 is made with a tube, or another linking agent which sufficiently connects the two vessels while adequately protecting and not inhibiting the flow of the solution of H₂O 20 between the two vessels. The second containment vessel 40 has an opening 44 of some sorts on the top portion of the second containment vessel 46. This opening 44 facilitates the addition of additional solution of H₂O 20 to the second containment vessel 40.

The solution of H₂O 20 travels through the connection 42 to the first containment vessel 10 either based off gravity or Bernoulli's principle of fluid dynamics. This flow adds the solution of H₂O 20 to the first containment vessel 10, and if both of the first containment vessel 10 and the second containment vessel 40 are level with one another, adjust the volume of the solution of H20 20 in each vessel so that they are equal.

Furthermore there is a hydrogen extraction point 50 located in the top portion of the first containment vessel 42. The hydrogen extraction point 50 is fashioned into the covering device 18 which is placed over top portion of the first containment vessel 12. Additionally the hydrogen extraction point 50 is, in an alternate embodiment, fashioned into the upper sides of the first containment vessel 16. The hydrogen extraction point 50 is operable to allow hydrogen gas to pass through the point 50. A multitude of devices attach to the hydrogen extraction point 50. One such device is a tubular connection 52 in which the hydrogen gas is led away from the first containment vessel 10. That tubular connection 52 leads to a hydrogen collection station 60 which is another remote containment vessel. Additionally that tubular connection 52, in an additional embodiment, leads to an incendiary device which produces a flame with the extracted hydrogen gas. Furthermore that tubular connection 52, in an additional embodiment, leads to a power generation unit which uses the extracted hydrogen gas as fuel. Moreover that tubular connection 52, in an additional embodiment, leads to an airship device which uses the hydrogen gas for lift and buoyance.

Still referring to FIG. 1, a stirring mechanism 70 is disposed into the interior of the first containment vessel 15. The stirring mechanism 70 extends through the top portion of the first containment vessel 12 and if there is a covering device 18, the stirring mechanism 70 extends through the covering device 18. The bottom end of the stirring mechanism 76 travels through the interior of the first containment vessel 15 and into the solution of H₂O 20 inside the first containment vessel 10.

Viewing now FIG. 2, as illustrated, the stirring mechanism 70 is viewed outside of the first containment vessel 10. The stirring mechanism 70, having a top portion of the stirring mechanism 72 is attached to a rotational device 80. This rotational device 80, in an additional embodiment, is a motor of some sorts. The rotational device 80 having at least an on and off operation phase rotates the stirring mechanism 70 when the rotational device 80 is in operation. Rotating the stirring mechanism 70 allows for the entire stirring mechanism 70 to rotate within the first containment vessel 10 and more importantly within the solution of H₂O 20.

Additionally the stirring mechanism 70 has a shaft portion 74. The shaft portion of the stirring mechanism 74 extends from the top portion of the stirring mechanism 72 to the bottom portion of the stirring mechanism 76. The shaft portion of the stirring mechanism 74 is produced from a material sufficient robust so that as the stirring mechanism 70 rotates, and so to the shaft portion of the stirring mechanism 74, the shaft portion of the stirring mechanism 74 will not bend or break during rotation. Additionally, the stirring mechanism 70 is protected by an insulation barrier 78 which encloses around the shaft portion of the stirring mechanism 74. The insulation barrier 78 extends the length of the shaft portion of the stirring mechanism 74 from the top portion of the first containment vessel 12 to below the highest point of the solution of H₂O 20 within the first containment vessel 10. By traveling the length of the shaft portion of the stirring mechanism 74 from the top portion of the first containment vessel 12 to below the highest point of the solution of H₂O 20 within the first containment vessel 10, the insulation barrier 78 creates an effective seal within the first containment vessel 10. This effective seal prevents the escape of produced hydrogen from traveling up the shaft portion of the stirring mechanism 74 and escaping through the top portion of the first containment vessel 12. Instead the released hydrogen travels into the interior of the first containment vessel 15 before traveling to the hydrogen extraction point 50. Because hydrogen is the lightest element and lighter than the air mixture inside the first containment vessel 10, hydrogen attempts to follow the path of least resistance to escape the interior of the first containment vessel 15. By extending the shaft portion of the stirring mechanism 74 into the solution of H₂O 20, a path of greater resistance is offered, and therefore the hydrogen bypasses such a path and flow into the interior of the first containment vessel 15 and in turn the hydrogen extraction point 50.

The stirring mechanism also has a bottom portion 76. Attached to the bottom portion of the stirring mechanism 76 is a wiping device 90. The wiping device 90 contains a multitude of attachments which will be given greater attention later. However, regardless of the formation of the wiping device 90, the wiping device 90 is positioned to be in contact with the metallic or semi-metal material 30. The wiping device 90 then gently rotates as the stirring mechanism 70 rotates. As the wiping device 90 is in contact with the metallic or semi-metal material 30, the wiping device 90 gently brushes the metallic or semi-metal material 30 within the solution of H₂O 20. This gentle brushing removes an impurity buildup on the surface of the metallic or semi-metal material 30 caused by the chemical reaction with the solution of H₂O 20 without damaging or removing any of the surfaces of the metallic or semi-metal material 30. Additionally this wiping device 90 discards the impurity buildups on the surface of the metallic or semi-metal material 30 to allow for the optimal chemical reaction to take place leading to a greater yield of hydrogen gas.

Turning now to FIG. 3, as illustrated, the wiping device 90 is viewed above a metallic or semi-metal material 30. The metallic or semi-metal material is viewed here as a cross section of multiple hollow cylinders stacked within one another. The wiping device 90 viewed in this illustration has a pitchfork shape with multiple prongs 100 extending downward from a support beam 110. The support beam 110 is then attached to the bottom portion of the stirring mechanism 76. Attached on either side of each of the prongs 100 on the pitchfork shaped wiping device 90 are wiping blades 120. These wiping blades 120 are made from a material which has no chemical reaction to either the metallic or semi-metal material 30 or the solution of H₂O 20. Additionally the wiping blades 120 attach to the bottom side of the support beam 110 between the prongs 100 of the pitchfork shaped wiping device 90. Furthermore although the illustrated figure shows wiping blades 120 attached to the wiping device 90 other types of attachments, in alternate embodiments, are used to wipe the metallic or semi-metal material 30. One such wiping attachment is a wiping pad attached to the prongs 100 and the support beam 110 of the pitchfork shaped wiping device 90. The wiping pad is a material which sufficiently removes impurity byproducts from the metallic or semi-metal material 30 while not chemically reacting with either the metallic or semi-metal material 30 or the solution of H20 20. Another type of wiping attachment, in an alternate embodiment, is soft bristles attached to the prongs 100 and the support beam 110 of the pitchfork shaped wiping device 90. The bristles are placed in multiple configuration such as but not limited to extending downward from the support beam 110 as well as extending outward from each side of the prongs 100 coincident with the longitudinal axis of the pitchfork shaped wiping device 90. Additionally, the bristles, in an alternate embodiment, completely surround the support beam 110 and the prongs 100, while extending outward in a pipe cleaner like formation. Finally, the bristles, in an alternate embodiment, surround the prongs 100 of the pitchfork shaped wiping device in a spiral arrangement extending radially outward from the prongs 100 as the spiral moves up and down the prongs.

The pitchfork shaped wiping device 90 is viewed above a cross sectional view of a metallic or semi-metal material 30. The metallic of semi-metal material 30 is a multitude of hollowed cylinders places inside one another. The prongs 100 of the pitchfork shaped wiping device 90 are evenly spaced so that when the stirring mechanism 70 is lowered in the first containment vessel 10 and further the solution of H₂O 20, the prongs 100 of the pitchfork shaped wiping device 90 slide between the walls 32 of the adjacent metallic or semi-metal material 30. With the pitchfork shaped wiping device 90 in place, the cleaning attachments 120 (blades, pads, or bristles) are in gentle contact with the metallic or semi-metal material 30. The rotational device 80 is then placed in an operational mode. In the operational mode the pitchfork shaped wiping device 90 rotates between the hollow cylinders of metallic or semi-metal material 30 gently removing impurity byproducts caused by the chemical reaction of the metallic or semi-metal material 30 and the solution of H₂O 20 while not damaging or removing parts of the metallic or semi-metal material 30 itself.

In FIG. 4 a single wiping blade 200 is viewed attached to the bottom of the support beam 210 forming the wiping device 90. The wiping device 90 is attached to the bottom portion of the stirring mechanism 76. The wiping blade 200 is in gentle contact with the top of the cylinder of metallic or semi-metal material 220 and the support beam 210 rotates to clean away impurity byproducts accumulating on the top surface of the cylinder of metallic or semi-metal material 220 caused from the chemical reaction between the solution of H₂O 20 and the metallic or semi-metal material 30. The wiping blade 200 does not damage or remove parts of the metallic or semi-metal material 30.

FIG. 5 is an alternate view of the cleaning attachment 120 in which the cleaning attachment 120 is made from bristles 300. The bristles 300 are viewed attached to the bottom of the support beam 310 forming the wiping device 90. The wiping device 90 is attached to the bottom portion of the stirring mechanism 76. The bristles 300 are in gentle contact with the top of the cylinder of metallic or semi-metal material 220 and the support beam 310 rotates to clean away impurity byproducts accumulating on the top surface of the cylinder of metallic or semi-metal material 220 caused from the chemical reaction between the solution of H₂O 20 and the metallic or semi-metal material 30. The bristles 300 do not damage or remove parts of the metallic or semi-metal material 30.

FIG. 6 is an alternate view of the cleaning attachment 120 in which the cleaning attachment 120 is a wiping pad 400. Instead of a support beam, a support disc 410 is shaped and attached to the bottom portion of the stirring mechanism 76. The wiping pad 400 is then attached to the support disc 410 to adequately cover the top surface of the cylinder of metallic or semi-metal material 220. The wiping pad 400 is in gentle contact with the top of the cylinder of metallic or semi-metal material 220 and the support disc 410 rotates to clean away impurity byproducts accumulating on the top surface of the cylinder of metallic or semi-metal material 220 caused from the chemical reaction between the solution of H₂O 20 and the metallic or semi-metal material 30. The wiping pad 400 does not damage or remove parts of the metallic or semi-metal material 30.

FIG. 7 is an alternate view of the cleaning attachment 120 in which the cleaning attachment 120 is a multitude of long thin bristles 450. In this alternate view there is no need for a support beam, instead the multitude of long thin bristles 450 attach to the bottom portion of the stirring mechanism 76 by way of a connection 460. The multitude of long thin bristles 450 is very voluminous and as such fan outwards from one another as they extend further from the connection 460 to the bottom portion of the stirring mechanism 76. The shape of this type of cleaning attachment 120 is similar to that of makeup brushes used in cosmetics. The connection 460 to the bottom portion of the stirring mechanism 76 is then centered over the center of the top surface of the cylinder of metallic or semi-metal material 250. The multitude of long thin bristles 450 is in gentle contact with the top of the cylinder of metallic or semi-metal material 220 and the shaft of the stirring mechanism 74 rotates to clean away impurity byproducts accumulating on the top surface of the cylinder of metallic or semi-metal material 220 caused from the chemical reaction between the solution of H₂O 20 and the metallic or semi-metal material 30. The multitude of long thin bristles 450 does not damage or remove parts of the metallic or semi-metal material 30.

FIG. 8, is an illustration of the wiping device 90 attached as part of the shaft section of the stirring mechanism 74. A wiping device 90 of this type is useful if the metallic or semi-metal material 30 used is a single hollowed out cylinder. FIG. 8 represents the wiping device 90 being wiping blades 500 attached to the sides of the bottom portion of the shaft of the stirring mechanism 74. The shaft of the stirring mechanism 74 and consequently the wiping blades 500 is then placed inside the hollow cylinder of the metallic or semi-metal material 510. The wiping blades 500 are in gentle contact with the sides of the cylinder of metallic or semi-metal material 530 and the shaft of the stirring mechanism 74 rotates to clean away impurity byproducts accumulating on the side surfaces of the cylinder of metallic or semi-metal material 530 caused from the chemical reaction between the solution of H₂O 20 and the metallic or semi-metal material 30. The wiping blades 500 do not damage or remove parts of the metallic or semi-metal material 30.

FIG. 9 performs similarly to the device illustrated in FIG. 8, however instead of wiping blades 500 being the wiping device 90 attached to the shaft of the stirring mechanism 74, bristles 550 are attached to the shaft of the stirring mechanism 74. The bristles 550 of the wiping device 90 are arranged in a spiral pattern extending up from the bottom of the shaft of the stirring mechanism 74. Additionally the bristles 550 extend radially outward form the center of the shaft of the stirring mechanism 74.

FIG. 10 is viewed as an additional embodiment of the disclosed system to produce hydrogen gas. The metallic or semi-metal material 630 is placed into the interior of the first containment vessel 610 and rest on the bottom of the first containment vessel 640. No specific shape of the metallic or semi-metal material 630 is necessary for this embodiment to operate as the metallic or semi-metal material 630 is random chunks, or in additional alternate embodiments, a large flat disc, miniature spheres, rectangle or any other possible shape. Additionally the metallic or semi-metal material 630, in an alternate embodiment, is an ingot combination in which hole or punctures are placed into the metallic or semi-metal material. The holes or punctures are filled with a solid caustic so that when water is added to the metallic or semi-metal material 630 in the first containment vessel 610, the caustic dissolves creating a solution of H₂O 20.

The wiping device 690 is attached to the bottom portion of the stirring mechanism 676. Furthermore the wiping device 690 has a support beam 620 extending the length of the first containment vessel 610. Attached to the bottom of the support beam 620 are long strands of fabric 650 the size of a bristle or larger. The envisioned long strands of fabric 650 are similar to those used in soft cloth car washes for cleaning automobiles. When the stirring mechanism 70 is in operation the long strands of fabric 650 drag along the bottom of the first containment vessel 640, gently dragging across the metallic or semi-metal material 630 arranged in the first containment vessel 610. If the first containment vessel 610 is a cylindrical shape, the stirring mechanism 70 rotates and the long strands of fabric 650 follow the rotation of the stirring mechanism 70.
