Gasification of carbonaceous materials)

Patent ·
OSTI ID:7010401
This patent describes a process for forming a gaseous fuel from finely divided solid carbonaceous material by charging fresh powdered solid carbonaceous material to a gaseous fuel-generation zone, charging steam to said generation zone where it contacts said material at temperatures within the range of from about 1500/sup 0/ to 2100/sup 0/F, withdrawing carbonaceous material from said generation zone, and mixing the withdrawn carbonaceous material with an oxygen-containing gas. This causing the said carbonaceous material to undergo at least partial combustion. The process continues by limiting the time period of combustion of said carbonaceous material within the limits of from about 0.5-0.7 second, separating the unburnt carbonaceous material from the resulting combustion fumes to prevent substantial reduction of the formed carbon dioxide and returning the thus heated carbonaceous material to the said generation zone for the purpose of supplying the heat necessary to support the gaseous fuel generation therein taking place.
