AN IMPROVED PROCESS FOR THE GASIFICATION OF COAL AND OTHER MINERAL-CONTAINING CARBONACEOUS SOLIDS

摘要

Agglomerate formation due to sintering is avoided in the nonslagging fluidized bed gasification of carbonaceous solids containing ash-forming, inorganic constituents by carrying out the gasification in the presence of an added hydrated aluminosilicate or an added hydrated magnesium silicate. In a preferred embodiment of the invention, the gasification zone is part of an integrated coking and gasification process wherein coal liquefaction bottoms are coked and the resultant coke is gasified.
