ABSTRACT:
Electrochemical gasification of carbonaceous materials by anodic oxidation produces oxides of carbon at the anode and hydrogen or metallic elements at the cathode of an electrolysis cell. In another embodiment carbonaceous materials are hydrogenated at the cathode by electrochemical reactions during which carbonaceous material may also be anodically reacted within the anode compartment of an electrolysis cell.
