            In producing liquid hydrocarbons with > 1 C atom in the molecule by the reduction of CO with H₂ in the presence of catalysts like those described in German Patent Appl. I 68,608 (abs. 3261). which contain Fe, Cu, alkali beside large amounts of MgO and Kieselguhr.  1 or more of the components is wholly or partly replaced by fluorine compounds or these are additionally incorporated therein.  Example: A catalyst of Fe, Cu, K, and MgO on kieselguhr has the MgO replaced by CaF₂.  With the same throughput, synthesis gas, and temperature, the CO conversion and the yield per m.3 of gas were both increased and the product contained a greater proportion of high-boiling constituents.
