        New catalysts of extraordinary efficiency are described, which differ from the previous Co catalysts by a very high CoCO₃ content, little kieselguhr, and a corresponding addition of Mn as activator.  They bring about complete transformation of the CO-H₂ mixture at the lowest temperatures known, below 170°.  This results in a high yield of paraffin.
