Slurry-phase gasification of carbonaceous materials using ultrasound in an aqueous media

Patent ·
OSTI ID:6355968
This patent describes a process for slurry-phase gasification of carbonaceous materials. It comprises: combining solid carbonaceous feedstock materials with a slurry liquid to form a feedstock slurry; conveying the feedstock slurry to a gasifier reaction vessel; gasifying the carbonaceous feedstock in the gasifier vessel in slurry phase at reaction temperatures from about 200{degrees} F. to about 1000{degrees} F. at elevated pressures and in the presence of water and an effective intensity of ultrasonic waves having a frequency of about 20 kHz to about 55 kHz to form product gases comprising primarily methane and carbon dioxide.
