ABSTRACT:
Catalyst for reducing carbon monoxide by means of hydrogen so as to obtain a mixture consisting substantially of C.sub.1 -C.sub.4 -hydrocarbons. The catalyst is made by precipitating a salt of a hydrocyanic acid of the general formula Me.sub.I Me.sub.II (CN).sub.x, separating and drying the salt so precipitated and forming it. In the formula, the cationic component Me I stands for at least one of the elements Ce, Cu, Co, Ni, Fe, Mn, Zn, Ag and K or a mixture of these elements, or for Ca or Mg in admixture with (NH).sub.4 ; the anionic component Me.sub.II stands for at least one of the elements Cu, Co, Ni, Fe, Mn, Zn and Ag or a mixture of these elements; and x stands for the sum of the metal valencies; Me.sub.I and Me.sub.II are not permitted to stand for iron alone, or for a mixture of iron with copper.
