The present disclosure relates to three-phase fuel compositions and particularly relates to a method for synthesizing a three-phase fuel composition.
Fossil fuels are considered as the most common energy resources for various industries. The rising costs of fossil fuels on one hand and the pollution caused by these non-renewable resources on the other hand have encouraged researchers to find a strategy to improve the efficiency of fossil fuels.
Liquid fuels, such as oil are the most commonly-used type of fossil fuels. Liquid fuels have two main shortcomings, namely, low efficiency and high pollutant emissions during combustion. Pollutants may negatively affect the weather and bring about problems, such as global warming, acid rains, and respiratory problems. Main pollutants emitted as a result of liquid fuel combustion include nitrogen oxide, unburned hydrocarbons, carbon dioxide, sulfur oxide, and soot. Moreover, consumption of liquid fuels may rise in response to the low efficiency of liquid fuels. One approach to address the low efficiency of liquid fuels may be redesigning liquid-fuel-burning motors, which may be unnecessarily complex and expensive.
Another approach for addressing the low efficiency of liquid fuels may be enhancing liquid fuels efficiency by adding various metals, metal oxides, and carbon nano structures to liquid fuels. For example, additives such as platinum, cobalt, radium, iridium, nickel, palladium, copper, silver, gold, zinc, aluminum, alumina, calcium oxide, titanium oxide, zirconium dioxide, iron oxides, ruthenium oxide, osmium oxide, cobalt oxide, radium oxide, iridium oxide, nickel oxide, silver oxide, gold oxide, zinc oxide, cerium oxide, carbon dots, carbon nanotubes, and graphene nano sheets may be added to fuels to increase their efficiency by improving air and fuel mixing. However, such additives still show poor efficiency-enhancement properties when used in liquid fuels, which may limit their usage.
One approach to further improve efficiency-enhancement properties of fuel additives may be utilizing nanostructures for storing flammable gases. For example, flammable gases may be stored in three-dimensional metal-organic frameworks. However, developing a safe method for the storage of flammable gases in such three-dimensional structures is crucial. To guarantee safe storage of flammable gases inside additives at room temperature, a coating may be required, which may be flammable when the liquid fuels ignite.
There is, therefore, a need for developing fuel-additive compositions that may be capable of storing flammable gasses. There is further a need for developing a method for producing a three-phase fuel that may allow for a safe storage of flammable gasses within the structure of the three-phase fuel.

In this example, an MIL-01 (Cr) adsorbent was synthesized by a method similar to method 100. To this end, 1 mmol chrome nitrate, 1 mmol terephthalic acid, and 1 mmol nitric acid may be added to 256 mmol deionized water. The mixture may be mixed for 10 minutes at 500 rpm. The mixture may be transferred to a teflon autoclave and may be heated at 220° C. for 8 hours. The adsorbent may be set aside to cool down to the room temperature. The mixture may be washed with water with a weight ratio of between 1:10 (adsorbent:water) to eliminate the chromium nitrate salt. After washing with water, the mixture may be filtered by for example, a filter paper. The product may be mixed with an ethanol solution for 6 hours at 500 rpm at 80° C. and then may be centrifuged at 9000 rpm for 10 minutes to eliminate unreacted terephthalic acid. This process may be repeated three times. The mixture may be mixed with DMF for 6 hours at 500 rpm at 80° C. The mixture may be centrifuged at 9000 rpm for 10 minutes. This process may be repeated three times. The mixture may be dried for 12 hours at room temperature.
After the washing process, the mixture may be purified by mixing the adsorbent with a pure ethanol solution at 80° C. for 2 hours at 500 rpm. After purification with ethanol, the adsorbent may be mixed with an ammonium fluoride solution with a concentration of 0.5 wt. % of ammonium fluoride salt in water for 6 hours.
which may be due to the presence of two types of micro-pore windows in the MIL-101 (Cr) adsorbent.
Table 1. Shows parameters of brunauer-emmett-teller (BET) and barrett-joyner-halenda (BJH) analysis related to the MIL-101 (Cr) adsorbent, consistent with one or more exemplary embodiments of the present disclosure. High surface area of the produced MIL-101 (Cr) in comparison with carbon-based adsorbents may be a superiority for the MIL-101 (Cr) adsorbent.
In this example, storing gases in an MIL-01 (Cr) adsorbent was performed by a method similar to method 100. To this end, 1 g of the MIL-101 (Cr) adsorbent may be added into a reactor. A pressurized reactor may be used to store gasses inside the pores of the adsorbent. The air inside the reactor may be vacuumed before injecting the gas and the reactor may be heated at a temperature of between 50° C. and 100° C. Then the reactor may be cooled to the ambient temperature. Oxygen may be purged into the reactor under a pressure of between 1 bar and 30 bar. The MIL-101 (Cr) adsorbent may be under pressure for between 1 minute and 5 minutes. Then sodium alginate may be spray coated on the sample to fully cover the adsorbent. The sample may be exposed to sodium alginate solution for between 1 minute and 10 minutes. For the next step, a calcium chloride dehydrate solution with the concentration of between 1 wt. % and 10 wt. % may be spray coated on the sample. The sample may be exposed to the calcium chloride dehydrate solution for between 1 minute and 10 minutes. The sample may be removed from the reactor and dried at a temperature of between 30° C. and 70° C.
In this example, stabilizing the MIL-01 (Cr) adsorbent inside the liquid fuel was performed by a method similar to method 100. To produce a three-phase fuel composition, 100 ppm of the sample prepared according to method 100 may be added to a diesel fuel. Oleic acid may be added to the liquid fuel as a surfactant with a weight ratio of 2:1 (surfactant:adsorbent). The mixture may be placed in an ultrasonic bath for 5 minutes.
To evaluate the effectiveness of the produced three-phase fuel composition, a single-cylinder-diesel engine connected to an eddy-current dynamometer may be used. To have a comparison, a diesel fuel and a diesel fuel containing three-phase fuel composition may be tested at room temperature with three repetitions. The engine performance parameters may be measured, such as power, specific fuel consumption, engine exhaust pollutants including CO2, NOx and HC. The results may show that using three-phase fuel composition may reduce break specific fuel consumption (BSFC) which may be due to the complete combustion. On the other hand, the presence of the MIL-101 (Cr) adsorbent particles may enhance mixing of the fuel and air by increasing the contact surface between air and the fuel. The presence of oxygen inside the MIL-101 (Cr) adsorbent may also lead to a complete combustion.
Exhaust emissions of diesel engines may also be examined. Results may show reduction in the pollutants.
Results may indicate that supplying sufficient oxygen in the combustion process when using three-phase fuel may enhance mixing of the fuel and air. HCs reduction of between 25% and 37% may be the response of the enhancement in the mixture of the fuel and air. The main reason of producing nitrogen oxides may be the high temperature in the combustion chamber. O atoms which may be the product of O2 decomposition at high temperature, may bind with nitrogen atoms in air and produce NO. Therefore, using three-phase fuel composition may lessen the emission of pollutants and increase CO2 production which may be a product of complete combustion.
In this example, storing methane in the MIL-01 (Cr) adsorbent was performed by a method similar to method 100. To this end, 1 gram of the MIL-101 (Cr) adsorbent which may be produced according to method 100, may be poured into a reactor and the reactor may be completely sealed. The temperature may be increased up to between 50° C. and 100° C. and the air may be vacuumed utilizing a vacuum pump. Methane may be injected to the reactor under a pressure of between 1 bar and 30 bar for between 1 minute and 5 minutes. The sodium alginate solution of example 1 may be spray coated on the adsorbent for between 1 minute and 10 minutes.
In this example, stabilizing methane inside the MIL-01 (Cr) adsorbent was performed by a method similar to method 100. To this end, 200 ppm of MIL-101 (Cr) adsorbent may be added to a diesel fuel and oleylamine may be added as the surfactant. Oleylamine may be added with a ratio of 1:1 of between surfactant and adsorbent to the mixture of fuels. The mixture of fuels and the surfactant may be mixed for 5 minutes.
To evaluate the effectiveness of the produced three-phase fuel composition, a single-cylinder-diesel engine connected to an eddy-current dynamometer may be used. To have a comparison, a diesel fuel and a diesel fuel containing three-phase fuel composition may be tested at room temperature with three repetitions. Results may indicate the increase of the engine power and the reduction of BSFC when using the three-phase fuel composition. Results may show the increase of between 7% and 11% of engine power and the reduction of between 4% and 7% in BSFCs. According to the results, a combination of gases may be used for producing the three-phase fuel composition.
