Literature Abstracts

Processing of coal as related to the 4-Year Plan is discussed. Low-, medium- and high-temperature carbonization, coal gasification, high-pressure hydrogenation, Fischer-Tropsch synthesis, coal dust engines, and colloidal fuel are reviewed. The manufacture of gasoline by coal hydrogenation will provide employment for 8,000 miners per million ton of gasoline produced, each ton needing 3.5 tons of coal. About 650,000 tons of gasoline by the I. G. Farbenindustrie A.-G. process and 150,000 tons by the Fischer-Tropsch process are already being produced in German plants. The capital cost of the Fischer-Tropsch plant is about one-half that of the I. G. Farbenindustrie A.-G. plant and has the advantage of using coke, 6-7 tons being required per ton of kogasin. The Pott-Broche extraction process is in use at the Mathias Stinnes mine. More than 85% of the coal substance is brought into solution. The Uhde process is under development in the Ruhr district. By these various means Germany will soon be independent of imported gasoline and light oils.
