Fiber reinforced zeolite extrudates with enhanced physical properties
The invention relates to a method of making a reinforced catalytic microporous and/or mesoporous bound composition comprising the steps of: providing a pre-formed catalytic crystalline material; mixing the catalytic crystalline material with water, a metal oxide binder, and a reinforcing glass fiber to form an extrudable composition; extruding the extrudable slurry under conditions sufficient to form the reinforced catalytic bound extrudate; and calcining the reinforced catalytic bound extrudate at a temperature and for a time sufficient to form a calcined reinforced catalytic bound catalyst. Advantageously, the reinforcing glass fiber can have a diameter from 5-100 microns and a length-to-diameter ratio from 300:1-3000:1 and can be present in an amount from about 1-50 parts, based on about 1000 parts combined of catalytic crystalline material and metal oxide binder.
