Abstract
Iron- and copper-containing heterogeneous catalyst, and a process for producing it, including the following steps: thermal decomposition of gaseous iron pentacarbonyl to give carbonyl iron powder having spherical primary particles; treatment of carbonyl iron powder with hydrogen, resulting in the metallic spherical primary particles at least partly agglomerating; surface oxidation of the iron particles to form iron oxide; contacting the particles with an aqueous solution of a copper compound; drying in the presence of oxygen and subsequent calcination in the absence of oxygen, resulting in oxygen-comprising copper compounds on the particles; and finally reaction of these with the iron oxide to form a mixed oxide of the formula CuFeO, where 0<x≦1. Process for preparing olefins by reacting carbon monoxide with hydrogen in the presence of a catalyst, wherein the abovementioned iron- and copper-comprising heterogeneous catalyst is used as catalyst.
