Title:
SYNTHESIS OF MOLECULAR SIEVE CATALYSTS
Document Type and Number:
WIPO Patent Application WO2002005950
Kind Code:
A3
Abstract:
Disclosed is a molecular sieve catalyst which contains molecular sieve-containing attrition particles and virgin molecular sieve, the attribution particles having been recycled from a catalyst manufacture process or from a reaction system. The catalyst can be used in a variety of catalytic reaction processes. A desired process is making olefins from an oxygenate feedstock. The recovery and use of the attrition particles in the catalyst is beneficial in minimizing waste, thereby reducing problems relating to both environmetal and economic constraints.
