ABSTRACT:
High concentrations of small (<4 microns) crystalline catalyst ingredients such as ZSM-5, low-soda exchanged Y-zeolite, ultra-stable Y-zeolite etc., can be incorporated into a durable matrix by use of binder formulations prepared from amorphous silica, alumina and zirconia, particularly those of colloidal dimensions. The binder formulations are slurried and associated with at least one active catalyst ingredient, which preferably is up to 60% ZSM-5. The resulting material is then spray-dryed and calcined to form binder matrices which are particularly resistant to attrition and particle density change.
