This invention provides a process for making an attrition resistant molecular sieve catalyst composition. The formation of highly attrition resistant catalyst particles is accomplished by initially mixing together catalyst components to form a slurry at a relatively low viscosity and high solids content. Preferably, a slurry having characteristics of high solids content and low viscosity is achieved using a rotor-stator mixer. Once the desired slurry characteristics are obtained, the slurry is dried, preferably by spray drying and calcining, to form a highly attrition resistant catalyst.
