3634. ---------------. [WEIR, H. M.] High-Pressure Gasification of Coal in Germany. Ind. Eng. Chem., vol. 39, 1947, pp. 48-54; Chem. Abs., vol. 41, 1947, p. 1079.
Details of the construction of equipment, typical operation, and costs for the continuous production of city gas directly from solid fuel and at high pressure at Böhlen, the first commercial installation in Germany to operate under the conditions described. The fuel used was in the form of a 3-10 mm. brown-coal coke and local brown coal itself. The plant had a capacity equivalent to 15,000,000 cu. ft. of gas at normal temperature and pressure per day. The fuel bed, 1-2 m. deep, in the generator was continuously blasted with a mixture of steam and O2. The crude gas produced contained some 30% CO2 and was under some 18 atm. pressure. Suitable cooling, removal of tar and distillate, and other purification under pressure produced a gas with the following typical analysis: H2, 48-49, CO, 22-24; CH4, 25-29%; the remainder being higher hydrocarbons, N2 and CO2. It had a normal heating value of 470-490 B.t.u. per cu. ft.
