Preparation of catalyst mixtures

摘要

Catalyst mixtures for the single stage conversion of syngas into an aromatic hydrocarbon mixture are prepared by spray drying an aqueous dispersion comprising a basic Zn/Cr containing precipitate and a crystalline metal silicate of specified structure. Intimate mixing of the catalyst components by spray drying gives a catalyst with a strongly improved C5<+>- selectivity and aromatics production. In view of their size, shape and strength the catalyst particles obtained are excellently suitable for application in fluid bed operation.
