Abstract
The present disclosure is directed to novel silicoaluminophosphate (SAPO)-based material with an SAT framework structure (topology type) (SAPO-SAT) that is substantially free of a non-SAPO-SAT phase, as well as the synthesis and use of that SAPO-SAT.
Claims21
A silicoaluminophosphate-based molecular sieve having an SAT framework structure (SAPO-SAT), wherein the SAPO-SAT is substantially free of a non-SAPO-SAT phase.
A process for the production of propylene from a methanol-containing feed, the process comprising:
- passing the methanol-containing feed to a reactor, wherein the reactor comprises a catalyst comprising a SAPO-SAT molecular sieve, wherein the SAPO-SAT molecular sieve is substantially free of a non-SAPO-SAT phase, and wherein the reactor is operated at reaction conditions sufficient to generate an effluent stream comprising propylene and having a propylene to ethylene ratio between about 1.6 and about 4.2.
A process for the production of propylene from a methanol-containing feed, the process comprising:
- passing the methanol-containing feed to a reactor, wherein the reactor comprises a catalyst comprising a MeAPO-SAT molecular sieve, wherein the MeAPO-SAT molecular sieve is substantially free of a non-MeAPO-SAT phase, wherein Me is cobalt or magnesium, and wherein the reactor is operated at reaction conditions sufficient to generate an effluent stream comprising propylene and having a propylene to ethylene ratio between about 1.6 and about 4.2.
