Production of C2+ Olefins

摘要

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.

主权项

1. 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 comprising at least one set of pores of substantially uniform size extending through the molecular sieve, wherein geometric mean of the cross-sectional dimensions of each of the pores is less than or equal to 5.3 Å; (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 C2+ olefin; and (d) separating at least part of the C2+ olefin from the product.
