This report aims at examining and supplying information on: the basic idea and its development of Lurgi Coal Gasification Process under Pressure started in 1934, and conditions and circumstances of development after the World War II; the further development of this process which started to proceed again in the limelight under the recent energy situations in spite of the fact that the coal gasification process seemed once forgotten by people until only recently since 1950 due to the abundant lowpriced oil supply of the past years; various problems concerning the coal as gasification raw material, i. e. grain size, ash, reactivity, caking property, etc., and how Lurgi process tries to solve those problems; description of this process itself; how Lurgi Coal Gasification Process is adopted and is or to be utilized in various countries of the world under the present energy situations; re-examination of the Combined Cycle Process for power generation in West Germany, SNG production based on coal in U. S. A., F-T Synthesis in South Africa and West Germany ; as well as coal gasification problems for synthesis gas for fertilizer production plants in the developing countries.
