Operation is carried out in the presence of Fe or Co catalysts suspended in a liquid medium. The synthesis gas is a CO-rich water gas, which is recycled through the converter, ratio of fresh gas to recycle gas 1 : 2 or 1 : 3. Following are the reaction conditions: Catalyst, 100 parts Fe, 5 Cu, 10 CaO, 100 kieselguhr; temperature, 240°-250°; pressure, 10 atm.; throughput, 1,000 1. fresh gas and 2,500 recycle gas per hr.; 10 1. 50% catalyst suspension; fresh gas, 38% CO and 48 % H₂; 100-120 gm. hydrocarbons per m.³ fresh gas are obtained. The hydrocarbons consist of 20% benzine, 50-65% soluble in H₂SO₄, 50% middle oil, b. 200°-320°, and 20% b. above 320°, of which 40-50% is olefins.
