Abstract: Processes for the conversion of gases into useable products as exemplified by the reaction of carbon monoxide and hydrogen to form paraffinic hydrocarbons, hydrogen and nitrogen to form ammonia, and water and carbon monoxide to form carbon dioxide and hydrogen may be effected at reaction conditions which include temperatures in the range of from about 200.degree. to about 700.degree. C. and pressures ranging from atmospheric to about 1000 atmospheres. The catalyst system which is to be employed to effect these reactions will comprise an iron-containing compound admixed with elemental copper, and potassium-, aluminum- and vanadium-containing compounds.

Abstract: Catalyst systems for the conversion of gases into useable products will comprise an iron-containing compound consisting essentially of elemental iron and a minimal amount of iron oxide. The system will also include the presence of from about 0.5% to about 4% by weight of elemental copper, from about 0.5% to about 4% by weight of aluminum oxide, from about 0.2% to about 5.0% by weight of vanadium oxide and from about 0.5% to about 5.0% by weight of a potassium-containing compound such as potassium oxide. This system will exhibit greater activity in the conversion of nitrogen and hydrogen to form ammonia, hydrogen and carbon monoxide to produce hydrocarbons, or water and carbon monoxide to form carbon dioxide and hydrogen.

Abstract: Aqueous alcoholic solutions such as hydrous alkanols may be converted to the corresponding aldehyde in a process which involves high conversion levels and high selectivity levels by treating the solution with an oxygen-containing gas in the presence of a catalyst comprising at least two oxides of metals selected from the group consisting of molybdenum, tungsten, cobalt, nickel, manganese, iron and chromium, one of said oxides being molybdenum oxide or tungsten oxide composited on a high surface area support. Reaction conditions which are employed in the process will include temperatures in the range of from about 200.degree. to about 400.degree. C. and a pressure in the range of from about atmospheric to about 50 atmospheres.
