Abstract

A process for the stabilization of particulate, activated catalyst masses after the activation of the starting catalyst masses in a gas stream, wherein the particulate, activated catalyst masses are removed from the activation reactor in an inert gas atmosphere into a liquid alcohol or a mixture of two or more alcohols which are straight-chain or branched-chain alcohols containing from 6 to 12 carbon atoms in the alkyl radical, stabilizing the catalyst masses by impregnation with the alcohol or the alcohol mixture, optionally storing and/or transporting the alcohol-impregnated catalyst masses, removing excess alcohol, sieving the alcohol-moist catalyst mass, and introducing the catalyst mass into a catalysis reactor to form a catalyst filling.
