Disposable catalyst for coal liquefaction
Research efforts being carried out at various universities on use of disposable catalysts in a slurry phase in the SRC-II process for coal liquefaction are very briefly highlighted. Pyrite, a major constituent of coal mineral matter, has been found to greatly enhance coal liquefaction, and this finding should point out that radical changes are needed in coal cleaning processes prior to liquefaction so that only inert and detrimental minerals are removed and catalytic minerals are retained. Addition of certain transition metal-containing ores and metallic wastes has shown substantial effectiveness as coal liquefaction slurry catalysts. Materials containing Mo, Fe, Co, and Ni performed best. Currently high surface area metal sulfides are being synthesized. These materials will be tested as liquefaction slurry-phase catalysts. (BLM)
