Abstract:
AROMATIC HYDROCARBON COMPOUNDS ARE SELECTIVELY REDUCED ELECTROCHEMICALLY TO THEIR 1,4-DIHYDRO DERIVATIVES IN AN AMMONIATED SOLVENT-ELECTROLYTE SYSTEM UNDER CONDITIONS SELECTED TO EFFECT OXIDATION OF AMMONIA.
Abstract:
This invention involves a process for recovering upgraded hydrocarbon products from a carbonaceous material selected from the class consisting of oil shale solids, tar sands solids, coal solids and a hydrocarbon fraction by contacting the carbonaceous material with a dense-water-containing fluid at a temperature in the range of from about 600.degree.F. to about 900.degree.F. in the absence of supplied hydrogen and in the presence of a sulfur- and nitrogen-resistant catalyst.
