Process for production of hydrogen from anaerobically decomposed organic materials
First Claim
1. A process for producing a gas stream from anaerobically digested organic materials containing volatile carboxylic acids formed during the anaerobic digestion of said organic materials, by the action of bacteria contained therein, said gas stream having enhanced levels of hydrogen and suppressed levels of methane relative to gases inherently produced from said anaerobically digested organic materials, comprising:
- (a) forming a reaction mass comprising said anaerobically digested organic materials;
(b) maintaining said reaction mass under anaerobic conditions;
(c) applying an electric potential across said reaction mass to cause the production of said gas stream containing enhanced amounts of hydrogen and suppressed amounts of methane; and
,(d) collecting said gas stream.

Abstract
A process for the production of hydrogen from anaerobically decomposed organic materials by applying an electric potential to the anaerobically decomposed organic materials, including landfill materials and sewage, to form hydrogen, and for decreasing the time required to treat these anaerobically decomposed organic materials. The organic materials decompose to volatile acids such as acetic acid, which may be hydrolyzed by electric current to form hydrogen. The process may be continuously run in sewage digestion tanks with the continuous feed of sewage, at landfill sites, or at any site having a supply of anaerobically decomposed or decomposable organic materials.

10. A process for producing an economically valuable gas stream from anaerobically digested organic materials containing volatile carboxylic acids formed during the anaerobic digestion of said organic materials by the action of bacteria contained therein, said gas stream having enhanced levels of hydrogen and suppressed levels of methane relative to gases inherently produced from said anaerobically digested organic materials, comprising:
-
(a) forming a reaction mass comprising said anaerobically digested organic materials; (b) maintaining said reaction mass under anaerobic conditions; (c) applying an electric potential across said reaction mass to cause the electrolysis of said carboxylic acids but not the electrolysis of water contained in said reaction mass, thereby causing the production of said gas stream containing enhanced amounts of hydrogen and suppressed amounts of methane; and
,(d) collecting a gas stream from said reaction mass substantially free of oxygen.
