Fluidized bed catalytic coal gasification process

Patent ·
OSTI ID:6808938

Coal or similar carbonaceous solids impregnated with gasification catalyst constituents are oxidized by contact with a gas containing between 2 volume percent and 21 volume percent oxygen at a temperature between 50/sup 0/ C. and 250/sup 0/ C. in an oxidation zone and the resultant oxidized, catalyst impregnated solids are then gasified in a fluidized bed gasification zone at an elevated pressure. The oxidation of the catalyst impregnated solids under these conditions insures that the bed density in the fluidized bed gasification zone will be relatively high even though the solids are gasified at elevated pressure and temperature.
