Abstract
Method of direct cooling synthesis gas in a catalytic reactor with one or more catalyst beds of a metal oxide catalyst being loaded on gas permeable partitions with distribution means, which method comprises admixing the synthesis gas during its passage through the reactor with a cooling gas being introduced into a mixing zone beneath each partition, wherein the mixing zones are obtained by passing a reducing gas through the catalyst bed, so that the catalyst volume shrinks during reduction of the catalyst particles, and, thereby, providing necessary cavities for the mixing zones beneath each partition.
