process for conversion of coal gasification and liquefaction using ionenausgetauschter coal particles

摘要

An improved method of distributing catalysts in coal comprising oxidizing the coal and ion-exchanging the active sites thus formed with a cation which exhibits catalytic activity when used in a subsequent coal conversion process. The ion exchange may be accomplished simultaneously with or subsequent to the oxidation step. After the ion exchange the coal can then be subjected to conversion via a gasification process. Ion exchange with the alkali and alkaline earth metal cations is particularly effective when the coal is subsequently converted via a gasification reaction. Incorporation of the cations into the coal via the method of this invention results in increased conversion rate and, generally, higher conversions to more desirable products. The method is particularly effective in the conversion of subbituminous and higher ranking coals and is most effective in processes wherein bituminous coal is converted.
