THE Synthetic Liquid Fuels Act (30 U.S.C., 321-325, and amendments) became law April 5, 1944, and a period of intensive research and development in this field was begun by the Federal Bureau of Mines. As part of this program, bulletins were published on pressure hydrogenation,3 the Fischer-Tropsch synthesis,4 and nil stifle.5 The. Bureau also has published a short bibliography on coal gasification,6 mostly of a theoretical nature. Because anal gasification is prerequisite to either the Fischer-Tropsch or coal-hydrogenation processes, publishing this sizable collection of technical information in this form Will Ire valuable. The material will he presented in three parts. as follows I. United Stares Patents. II. United Kingdom, Australian, Canadian, and South African Patents. III. Other Foreign Patents. Part I appeared in early 1960. Part II follows.

THE Synthetic Liquid Fuels Act (30 U.S.C., 321-325, and amendments) become law April 5, 1644, and a period of intensive research and development in this field was begun by the Bureau of Mines. As part of this program bulletins were published on a pressure hydrogenation,3 the Fischer-Tropsch synthesis,4 and oil shale.5 The Bureau also has published a short bibliography on coal gasification,6 mostly of a theoretical nature. Because coal gasification is prerequisite to Hither the Fischer-Tropsch or coal-hydrogenation processes, publishing this sizable, collection of technical information in this form will be valuable. The material is presented in three parts, as follows: I. United States Patents. II. United Kingdom, Australian, Canadian, and South African Patents. III. Belgium, French, German, Italian, and Swedish Patents. The domestic patents for this bulletin were collected between 1963 and 1955.
