| 20110220351 | PROCESS FOR GENERATING HYDROGEN - The invention provides a process for the production of hydrogen in a subterranean hydrocarbon reservoir, said process comprising the steps of introducing a metal-based catalyst into a hydrocarbon-containing zone in said reservoir; raising the temperature in said zone to a temperature at which catalyzed conversion of hydrocarbon to hydrogen occurs; and, optionally but preferably, recovering hydrogen from an extraction section of a production well located above said zone. | 09-15-2011 |
