Abstract

A process for preparing olefins by reaction of carbon monoxide with hydrogen in the presence of a an iron-comprising heterogeneous catalyst produced by 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 partially forming agglomerates; contacting the agglomerates with iron pentacarbonyl; and thermal decomposition of the iron pentacarbonyl to give at least predominantly pore-free and void-free secondary particles.
