ABSTRACT:
Highly stable and active catalysts are provided for the alkylation of aromatic hydrocarbons with C.sub.2 -C.sub.4 olefins. The catalysts are extruded composites of an acidic, crystalline aluminosilicate zeolite, e.g. Y zeolite, and a porous mineral oxide binder. The basic novel feature of the invention resides in the shape and size of the catalyst extrudates. By shaping the extrudates so as to give a high ratio of external surface area to volume, resistance to deactivation is found to be much improved, as well as activity and selectivity.
