Role of non-ferrous coal minerals and by-product metallic wastes in coal liquefaction. Technical progress report, September 1, 1980-November 30, 1980
The effects of minerals and inexpensive ores or by-products (pyrites, red mud, flue dust, speculites, zinc sulfides, calcium oxide, dolomites, mica, molybdenite) in catalysing coal liquefaction or the hydrogenation of process solvents was studied with different cokes and solvents. Improved results were obtained in several cokes and th results are given in terms of oil fields, hydrogen consumption, desulfurization of SRC, etc. The addition of pyrite resulted in increased production of oils and increased conversion of coal; however, the effects varied from coal to coal. Dolomite, mica and molybdenite had insignificant catalytic activity. The reduction of pyrite, Fe/sub 2/O/sub 3/ and Fe/sub 3/O/sub 4/ at process conditions was studied. (LTN)
