PREPARING CRYSTALLINE SILICATE CATALYST AND USE IN PREPARING AROMATIC HYDROCARBON 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.
