        Review and digest of recent CIOS reports on gasification processes under 4 headings:  Processes (1) in which fine fuel is gasified in a fluidized bed (example, the Winkler process); (2) in which fine fuel is gasified in suspension (example, Koppers and Schmalfeldt processes); (3) in which fine fuel is gasified in a fixed bed (example, the Lurgi process; (4) in which lump fuel is gasified in a fixed bed (example, the Thyssen-Galocsy slagging generator and the Leuna slagging generator).  Typical operating data are given for each process, and diagrams of the plants are shown.  The economics of O₂ production by the Linde-Fränkl process is presented.  It is stated that power requirements in Germany for producing O₂ of 98% purity were about 12 kw.-hr. per 1,000 cu. ft. and that in plants of 75,000 cu. ft. per hr., capacity the cost of power was 50% of the total cost, amortization and interest 40%, and labor and materials 10%.  If the same relations between power costs and other costs should prevail in America, O₂ of 98% purity should be obtainable for $0.12 per 1,000 cu. ft. with power at $0.005 per kw.-hr.
