Abstract
A process for slurry-phase gasification of carbonaceous feedstock materials is provided wherein feedstock materials are combined with a liquid to form a feedstock slurry. Product gases are formed from the feedstock slurry in a gasifier reaction vessel in the presence of elevated temperatures and pressures and ultrasonic energy. Gasification catalysts may be utilized to provide increased reaction rates. The process of the present invention provides enhanced conversion of carbonaceous solids feedstock to gaseous products comprising primarily methane and carbon dioxide with some higher organic liquids.
