Coal as a feedstock

The Institution of Chemical Engineers Subject Group on Coal Utilization held a well attended symposium on ‘Coal as a Feedstock’ on 15 December 1987 at British Gas Midlands Research Station, Solihull, to review current noncombustion uses of coal, and to reassess its future potential as a feedstock. G. Kimber of British Coal reviewed direct coal liquefaction with reference to current demonstration processes, showing how transport fuels with specification similar to petroleum derivatives could be produced for blending. He particularly emphasized the higher thermal efficiency of direct liquefaction in comparison with routes to coal liquids via synthesis gas. H. Davies of the British Gas plc outlined some of the research activities of the world’s largest gas company in the production of substitute natural gas (SNG). Within the context of available coal gasification technology, he discussed the advantages of the Lurgi slagging gasilier: lower operating temperature,

production of smaller quantities of liquor and a higher carbon inventory. The use of the British Gas gasifier in a combined cycle for electricity generation from coal would also have a number of advantages, especially the greater ease of removal of nitrogen and sulphur oxides than in coal combustion. The changing use of coal in UK steelmaking was discussed by J. Monson of the British Steel Corporation. While the decline in steel production was inevitably reflected in a reduced demand for coal, a number of interesting developments in coal use are taking place: direct injection of coal into the blast furnace, and direct reduction processes for iron-making in which reduction and melting are separated. K. Clarke described how a range of chemicals, notably phenols and their derivatives, are derived from the lowtemperature tar resulting from smokeless fuel manufacture. Chlorination and alkylation to produce biocides and

antioxidants are used to yield high-value products. Coal-derived chemicals of this type have a small but valuable share of the market, although the problems of waste disposal and product quality must continually be addressed. Finally, L. Dick gave a detailed account of the South African coal chemical industry. The manufacture of 40% of that country’s transport fuels from coal via Fischer-Tropsch synthesis from syngas is of continuing interest, but the increasing importance of coal-derived methanol as a gasoline diluent or straight fuel is also noteworthy. The large-scale synthesis of polymers from acetylene, derived from calcium carbide, is another intriguing aspect. The discussion following these papers ranged from the environmental and sociological consequences of future coal use to more technical questions, for example on coal quality and uniformity. These aspects were drawn together by the panel of speakers: overseas experience suggests that coal is best used when one large mine supplies a large nearby plant.
