Koppers-Totzek A coal gasification process using an entrained bed. The coal is finely ground and injected in a jet of steam and oxygen into a circular vessel maintained at 1,500°C. Reaction is complete within one second. The ash is removed as a molten slag. The process was invented by F. Totzek at Heinrich Koppers, Essen, and further developed by Koppers Company in Louisiana, MO, under contract with the U.S. Bureau of Mines. The first commercial operation was at Oulu, Finland, in 1952 by 1979, 53 units had been built. Most of the plants are operated to produce a hydrogen-rich gas for use in ammonia synthesis. Developed by Lurgi. See also PRENFLO. 

Degussa developed the BMA (Blausaure-Methan-Ammoniak, or HCN-methane-ammonia) process around 1949 in cooperation with Heinrich Koppers GmbH. In the process, ammonia reacts with methane in the absence of oxygen in a gas-fired tubular reactor. US patent 5,785, 942 describes the BMA process and improvements that were made during the mid 1990 s. The reaction is46 ...
