Use of alkaline earth metal containing small pore non-zeolitic molecular sieve catalysts in oxygenate conversion

摘要

The present invention is directed to a catalyst composition comprising a non-zeolitic molecular sieve and one or more alkaline earth metals selected from the group consisting of strontium, calcium, barium, and mixtures thereof, wherein said non-zeolitic molecular sieve has a pore diameter size of less than about 5 Angstroms.
