Patent ID: 7151199

Claim:
A conversion process selected from the group consisting of oxygenate conversion to olefins, oxygenate and ammonia conversion to alkylamines, and hydrocarbon conversion comprising cracking, hydrocracking, isomerization, polymerisation, reforming, hydrogenation, dehydrogenation, dewaxing, hydrodewaxing, alkylation, transalkylation, dealkylation, hydrodecyclization, disproportionation, oligomerization, dehydrocyclization or combinations thereof, the process comprising the steps of: (a) introducing a feedstock to a reactor system in the presence of a catalyst comprising a non zeolitic molecular sieve, inorganic oxide matrix, and matrix material, wherein the catalyst contains from 10 ppm to 600 ppm by weight halogen; to thereby carry out a reaction process which converts said feedstock into a gaseous effluent stream containing one or more conversion products; (b) withdrawing from the reactor system said gaseous effluent stream; and (c) passing the effluent gas through a recovery system recovering at least the one or more conversion products.
