Claims
- 1. A continuous process for the production of a gaseous product by reaction of a liquid reagent, the process comprising:
- introducing the liquid reagent continuously into a reactor having an inlet and an outlet in order to obtain a gaseous product and a liquid product, wherein a positive difference exists between the pressure at the inlet to the reactor and the pressure at the outlet of the reactor, which positive difference is kept constant.
- 2. A process according to claim 1, wherein the reactor contains solid particles of catalyst.
- 3. A process according to claim 1, wherein the difference in pressure ranges from 0.0001 to 0.01 MPa.
- 4. The process according to claim 1 applied to the production of oxygen by catalytic decomposition of hydrogen peroxide,wherein the liquid reagent is an aqueous solution of hydrogen peroxide, the reactor contains a decomposition catalyst for hydrogen peroxide having the form of solid particles, and wherein the gaseous product is a gaseous mixture containing oxygen and water, and the process comprises the further steps of
- cooling the gaseous mixture in a condensation zone to form a gaseous phase consisting essentially of oxygen and a liquid phase comprising water; and
- removing the liquid phase, wherein the positive difference between the pressure of the aqueous solution of hydrogen peroxide at the inlet to the reactor and the pressure of the gaseous phase consisting essentially of oxygen in the condensation zone at the outlet of the reactor is kept constant.
- 5. A process according to claim 4, wherein an aqueous solution containing from 15 to 65% by weight hydrogen peroxide is used.
- 6. A process according to claim 4, wherein the solid particles of catalyst contain a catalytic element chosen from among lead, platinum and palladium.
- 7. A process according to claim 6, wherein the catalyst is composed of platinum on an alumina support.
- 8. A process according to claim 2, wherein the reactor comprises in its upper part a zone which is not submerged and is free from catalyst.
- 9. A continuous process for the production of a gaseous product by reaction of a liquid reagent, the process comprising:
- introducing the liquid reagent from a storage tank continuously into a horizontal reactor having an inlet and an outlet in order to obtain a gaseous product and a liquid product, wherein the storage tank is positioned above the horizontal reactor and a positive difference exists between the pressure at the inlet to the reactor and the pressure at the outlet of the reactor, which positive difference is kept constant.
- 10. The process according to claim 9, wherein the horizontal reactor contains solid particles of catalyst.
- 11. The process according to claim 10, wherein the horizontal reactor comprises in its upper part a zone which is not submerged and is free from catalyst.
- 12. The process according to claim 9, wherein the difference in pressure ranges from 0.0001 to 0.01 MPa.
- 13. The process according to claim 9 applied to the production of oxygen by catalytic decomposition of hydrogen peroxide, wherein the liquid reagent is an aqueous solution of hydrogen peroxide, the horizontal reactor contains a decomposition catalyst for hydrogen peroxide having the form of solid particles, and the gaseous product is a gaseous mixture containing oxygen and water, and the process comprises the further steps of
- cooling the gaseous mixture in a condensation zone to form a gaseous phase consisting essentially of oxygen and a liquid phase comprising water; and
- removing the liquid phase, wherein the positive difference between the pressure of the aqueous solution of hydrogen peroxide at the entrance to the horizontal reactor and the pressure of the gaseous phase consisting essentially of oxygen in the condensation zone at the outlet of the horizontal reactor is kept constant.
- 14. The process according to claim 12, wherein an aqueous solution containing from 15 to 65% by weight hydrogen peroxide is used.
- 15. The process according to claim 12, wherein the solid particles of catalyst contain a catalytic element chosen from among lead, platinum and palladium.
- 16. The process according to claim 15, wherein the catalyst is composed of platinum on an alumina support.
