This plant is owned jointly by the Ruhrchemie A.-G., the I. G. Farbenindustrie A.-G., and Henkel & Co. it is damaged very little and could produce 10,000 tons per year of products within 3 mo. Olefins of the C₁₁-C₁₇ fraction, obtained by cracking in a Dubbs-type furnace of a C₂₀-C₄₀ Fischer-Tropsch fraction, are treated with water gas in the liquid phase at approximately 150 atm. to produce a mixture of straight-chain aliphatic aldehydes and ketones, the former of which are reduced to the corresponding alcohols. Yields of olefins of approximately 50% are obtained in the cracking unit at 400°-450°. The converter is charged with a 50% suspension of the catalyst (90% Co, 7% ThO₂, 3% MgO, deposited as carbonates on kieselguhr) in the liquid olefins, and water gas is admitted at the bottom at 150 atm. pressure. Temperatures range 150°-180°, the higher temperature favoring aldehyde production but reducing the yield owing to polymerization. The yield of alcohols is approximately 1 lb. per lb. of olefins. The process may be carried out with C₂H₄ for production of lower aldehydes, particularly propionaldehyde, at temperatures of 85° and 70% yield. The catalyst can be used 50-100 times without regeneration. The oxygenated compounds are separated from the unreacted olefins by fractional distillation.
