Abstract
This disclosure relates to the conversion of methane to higher molecular weight (C5+) hydrocarbon, including aromatic hydrocarbon, to materials and equipment useful in such conversion, and to the use of such conversion for, e.g., natural gas upgrading.
Claims11
A process for producing aromatic hydrocarbon, the process comprising:
- (a) providing a feed comprising at least one C2+ aliphatic hydrocarbon, at least one C1+ organic oxygenate and at least 9 mole % of methane, the mole percent being based on per mole of feed, wherein the molar ratio of methane to C1+ organic oxygenate in the feed is in the range of 0.6:1 to 20:1 and the molar ratio of methane to C2+ aliphatic hydrocarbon in the feed is in the range of from 0.1:1 to 20:1;
- (b) contacting the feed with a catalyst comprising at least one molecular sieve and at least one dehydrogenation component under conditions, including a temperature <700° C., effective to convert at least part of the methane, C2+ hydrocarbon and C1+ organic oxygenate in the feed to a product comprising at least 5 wt. % of C5+ hydrocarbon based on the weight of the product, wherein the molecular sieve comprises at least one of ZSM-12, ZSM-22, ZSM-23, ZSM-48, UZM-8, a molecular sieve of the MCM-22 family, or mixtures or intermediates thereof;
- and
- (c) separating at least part of the C5+ hydrocarbon from the product.
