Abstract
The invention relates to a molecular sieve catalyst composition, to a method of making or forming the molecular sieve catalyst composition, and to a conversion process using the catalyst composition. In particular, the invention is directed to a conversion process for producing olefin(s), preferably ethylene and/or propylene, from a feedstock, preferably an oxygenate containing feedstock in the presence of a molecular sieve having been synthesized in the presence of a flocculant.
Claims22
A process for producing one or more olefin(s), the process comprising the steps of:
- (a) introducing a feedstock to a reactor system in the presence of a molecular sieve catalyst composition comprising a synthesized molecular sieve having been recovered in the presence of a polymeric amine flocculant;
- (b) withdrawing from the reactor system an effluent stream;
- and
- (c) passing the effluent gas through a recovery system recovering at least the one or more olefin(s).
An integrated process for making one or more olefin(s), the integrated process comprising the steps of:
- (a) passing a hydrocarbon feedstock to a syngas production zone to producing a synthesis gas stream;
- (b) contacting the synthesis gas stream with a catalyst to form an oxygenated feedstock;
- and
- (c) converting the oxygenated feedstock into the one or more olefin(s) in the presence of a molecular sieve catalyst composition, the molecular sieve catalyst composition comprising a synthesized molecular sieve having been recovered in the presence of a polymeric amine flocculant.
