High yield of solid paraffin is obtained (100-123 gm. per m.³ of gas) by passing a mixture of CO and H₂ (1:2) at a temperature < 250° and a pressure 4-20 atm., over a fixed Co catalyst previously impregnated with paraffin and arranged in such a manner that the paraffin formed can be continuously evacuated.
