Title: Improvements in or relating to the production of hydrocarbons and oxygenated organiccompounds
IPC: C07C1/12
Filed: 1947-07-25
Abstract: A gaseous mixture comprising hydrogen and carbon monoxide or dioxide is passed continuously upwards in a reaction zone through a mass of finely-divided hydrogenating metal catalyst to suspend the same in said stream, the feed rate being equivalent to at least 1.1 standard cubic feet of carbon oxide per hour per pound of catalyst in the dense fluidized mass, the gaseous mixture then being withdrawn and hydrocarbons and oxygenated products recovered.  Iron, cobalt or nickel or their oxides with minor amounts of promoters may be used. Preferably the greater proportion of the catalyst is smaller than 100 microns including at least 25 weight per cent smaller than 37 microns.  Initial catalyst concentrations may be at least 30, e.g. 40-120 or more, pounds per cubic foot.  Temperatures may be 350-750 DEG  F., preferably 550-750 DEG  F., with iron; below 450 DEG  F. with cobalt. The ratio of hydrogen to carbon monoxide is preferably at least 2: 1, e.g. above 5: 1, and the superficial velocity 0.1-10 ft./sec. At high H2: CO ratio, catalyst regeneration is unnecessary. Unconverted gases may be recycled.  In examples: (1) the catalyst is prepared from an ammonia synthesis catalyst by reduction in hydrogen and grinding, and is used at varying reaction conditions with a feed gas having a H2: CO ratio of about 2: 1 and feed ratio between 1.8 and 6.7 standard c.ft. CO/hr./lb., the products being mainly gasoline, diesel oil, and oxygenated compounds, chiefly alcohols; (2) the H2: CO ratio of the fresh feed varies from 1.3-2.7: 1 and the ratio is increased by recycle of unconverted gas.  Feed rates range up to 24 c. ft. CO/hr./lb.; (3) and (4) results of operation under other reaction conditions are given.  Specification 591,989 is referred to.
