Abstract

A process for the manufacture of catalyst moldings from granular catalyst material, preferably iron ore, chromium ore or a similar ore, with the use of a binder is disclosed. The granular catalyst material is thermally pre-treated in a temperature range of approximately 250.degree. to 1000.degree. C., before it is mixed with dilute and/or concentrated sulfuric acid functioning as the binder.
