Abstract
This disclosure relates to the production of C2+ olefins from feeds containing methane and at least one co-reactant, to equipment and materials useful in such processes, and to the use of such olefins in, for example, the production of polymers.
Claims19
A process for producing one or more of C2+ olefin, the process comprising:
- (a) providing a feed comprising at least 9 vol. % of methane and at least 4 vol. % of at least one co-reactant selected from the group consisting of C2+ alkane, syngas, and alcohol;
- (b) providing a catalyst comprising at least one molecular sieve, the molecular sieve having a framework of AFX, ERI, CHI, LOV, NAB, NAT, RSN, STT, VSV, or mixtures thereof;
- (c) contacting the feed with the catalyst under conditions, including a temperature of no more than 700° C., effective to convert at least part of the methane and co-reactant in the feed to a product comprising at least one C2+ olefin, wherein from 5 wt. % to 50 wt. % of the methane in the feed is converted;
- and
- (d) separating at least part of the at least one C2+ olefin from the product.
