Method for preparing a low acidity refractory oxide-bound zeolite catalyst.

摘要

A method for preparing a catalyst comprising a zeolite and a low acidity refractory oxide binder which is essentially free of alumina which method comprises:(a) preparing an extrudable mass comprising a substantially homogenous mixture of zeolite, water, a source of the low acidity refractory oxide binder present which comprises an acid sol, and an amine compound,(b) extruding the extrudable mass resulting from step (a),(c) drying the extrudate resulting from step (b); and,(d) calcining the dried extrudate resulting from step (c).
