2971. ---------------. [RUHRCHEMIE, A.-G.] [Olefin Synthesis by Water-Gas Circulation on Cobalt-Mixture Catalyst.] FIAT Reel L-5, Apr. 29, 1941, frames 118-135; PB 70,159; TOM Reel 299.
Synthesis operation was carried out in a double-tube furnace to obtain products with a high % of olefins. According to calculations, 1 m.3 of water gas was needed to circulate for each 10 m.3 of Co catalyst mixture; however, the quantity had to be increased to 1.2 m.3 during the operation. The results of the synthesis, as obtained under normal conditions in a range of temperature 190°-225°, a gas pressure of 7 atm., and a catalyst life of 6 mo., are as follows: CO+H2 conversion 63%; yield of liquid products 88-90 gm. per m.3 of water gas; 52 wt. % benzine; 25, oil; 17, soft paraffin; 6, hard paraffin; olefins in benzine, 58-60 vol. % and in oil 42 vol. %.
