United States Patent 2,560,171, July 10, 1951; appl. filed Mar. 3, 1947, Serial No. 731,899; 3 claims (Cl. 260-449.6). Describes improved process for producing organic compounds by introducing a feed mixture containing H2 and CO in a mol ratio of H2 : CO between 0.7 : 1 and 10 : 1 into a reaction zone through which a gaseous mixture is passed upward at 0.5-40 ft. per sec. in presence of a fluidized catalyst and under conditions such that a major part of the CO is converted. The reaction zone is maintained at 350°-750° F. and 50-500 p. s. i. g. A gaseous effluent is withdrawn from the reaction zone, a part recycled in a volumetric ration of recycle gas to fresh feed of between 1 : 1 and 2 : 1. Hot regernerated catalyst is introduced into the mixture of recycle gas and fresh feed, the temperature differential between catalyst and feed is decreased and the catalyst returned to the reaction zone. The unrecycled effluent is subsequently cooled and condensed, and the organic products are recovered. Using a reduced Fe catalyst under the conditions described a conversion of 70-100% of CO has been observed. The oil and H2O yields have been as much as 100 and 120 cc. per m.3, respectively. Substantial amounts of oxygenated compounds have been recovered. ------. See abs. 488, 2196, 2202. HILLARD, G. O. See abs. 2585, 2586. |
