1684. ------. [INTERNATIONAL HYDROCARBON SYNTHESIS CO.] [Hydrocarbons From Carbon Monoxide by Hydrogenation With a Catalyst.] Netherlands Patent 55,360, Oct. 15, 1943. Chem. Abs., vol. 41, 1947, p. 3280.

Catalyst is prepared by precipitating a solution of Fe and Ca salts with alkali hydroxide; the Ca content, calculated as CaO or Ca (OH)₂, is at least 5% of the Fe content; for example, Fe 259 gm. in form of Fe(NO₃)₃·H₂O and CaO 10 gm. as Ca (NO₃)₂ were dissolved in 600 gm. H₂O and heated to boiling. To this solution is added 425 cc. 40% NaOH, specific gravity 1.438, at least at 50° . After stirring and filtering, the residue was washed 2 times with 350 cc. H₂O at 80° -90° until the nitrate content was under 1.5%. The hydroxides were dried and reduced with the synthesis gas or with H. They can be impregnated with alkali solution and 2-5% Cu or Ni may be added.
