30. --------------. [ALLNER, W.] [Production of City Gas and Gas for Synthesis From Brown Coal by the Continuous-Current Gas Process.] Ztscher. Ver. deut. Ing., vol. 79, 1935, pp. 1487-1492; Coal Carbonisation, vol. 2, 1936, p. 18; Chem. Abs., vol. 30, 1936, p. 1542.
Kassel plant of the Braunkohlen and Brikett Industrie A.-G., Bubiag, for degasifying brown coal by parallel-flow process is described. The raw-gas yield for purposes of synthesis amounts to 1,100-1,800 m.3 per ton at normal temperature and pressure. The CO:H2 ratio can be adjusted exactly to 1:2 to suit the Fischer benzine-synthesis process without special preparation. An installation of 12 parallel-flow retorts 32 ft. 10 in. in height has been in continuous service in Hungary since 1932, making about 70,000 m.3 of synthesis gas per day. Plants of any desired capacity can be supplied under guarantee for the manufacture of town gas or synthesis gas.
