Brief review of modern methods for converting coal, both directly and indirectly, into motor fuels, oils, and other products is given. In the Fischer-Tropsch process the purified gases from the gasification of coal or coke are passed through Ni and Co oxide catalysts at atmospheric pressure and about 400° F. High-quality lubricating oils may be made from the primary product by the thermal cracking of the middle oil and polymerization of the olefinic products with AlCl₃ catalyst. Yields of about 35%, by weight, have been claimed, although these may be considerably higher if Fischer’s claims are justified for the direct production of unsaturated oils by the use of an Fe catalyst at 15-20 atm. pressure.
