标题:Electrochemical synthesis of humic acid and other partially oxidized carbonaceous materials
发明人：VAUGHAN RONALD J; BY BANK OF AMERICA NT SA ADMIN
权利人:CHEVRON RES
摘要:A continuous cyclic electrolytic/carbon oxidation process wherein ferrous ion is oxidized at the anode and hydrogen is generated at the cathode of an electrolytic cell. The ferric ions produced at the anode are thereafter reduced to ferrous ions by contact with a solid carbonaceous material and the ferrous ions recycled for electrochemical reoxidation. The process produces partially oxidized organic products from the combustion process in high yield.
