Fe catalysts that give synthesis products unusually rich in oxygenated compounds, such as alcohols and ketones, may be prepared by keeping the finely divided metal particles constantly agitated in the oxidizing gas. The reduction also takes place with the Fe in dense Suspension. The oxidation and reduction temperature range is 600°900° F. A promoter may be added to the Fe before or after the oxidation step. 1 literature ref. and 14 United States patents cited.
