Patent Abstracts

Hydrocarbons and oxygenated organic compounds are produced by treating an oxidized Fe-type catalyst free from carbonaceous material with a gaseous mixture of CO and H₂ at 343º-399º and 0-450 p. s. i. g. for 30 min. to 12 hr., and then reducing the temperature 10º-93º to form a substantial amount of the products. In an example, Fe oxide catalyst, to which has been added 2% by weight K₂CO₃, based on the catalyst weight, was divided into 2 portions. One part was pretreated by passing a mixture consisting of equal parts of H₂ and CO into contact with it at 343º-399º and 0 lb. pressure for 1 hr. The other part was treated in a conventional manner with H₂ at 482º for 4 hr. Each portion was then used to synthesize hydrocarbons by contact with a gaseous mixture of equal parts of CO and H₂ at the rate of 200 vol. feed gas per vol. Catalyst per hr., 288º and 150 p. s. i. g. In the case of the 1^st portion, 172 cc. C₄ and heavier hydrocarbons per m.³ H₂ and CO consumed were produced. With the 2d portion only 120 cc. Of the hydrocarbons were formed.
