Abstract:
1. A method for making a molecular sieve catalyst composition, the method comprising the steps of: combining a molecular sieve, a binder, and a matrix material, wherein the weight ratio of binder to molecular sieve is greater than 0.1 to less than 0.5; spray drying the resulting combination and thereafter calcining the spray dried product in a rotary bed calciner, fluid bed calciner or batch oven at a temperature of from about 400° C. to 1000° C. in a calcination environment selected from air, nitrogen, helium, flue gas, and combinations thereof, wherein the resulting molecular sieve catalyst composition has micropore surface area (MSA) of at least 70% of the MSA of the molecular sieve.
