Claim:
1. A process for producing xylenes, the process comprising: (a) providing a feed comprising methane, hydrogen, and carbon monoxide, in which the molar ratio of hydrogen to carbon monoxide is from 0.5 to 6 and in which the molar ration of methane to carbon monoxide is from 25 to 1; (b) contacting the feed with (i) a first catalyst comprising at least one metal or compound containing a metal selected from the group consisting of Ce, Zn, Zr, and Th, and (ii) a second catalyst comprising at least one medium pore size molecular sieve, wherein the contacting in (b)(i) and (b)(ii) is carried out under conditions including a temperature of at least 350° C. and a pressure of at least 1500 kPa (absolute) effective to produce a reaction effluent containing benzene, toluene, and xylenes; and (c) subjecting at least part of the reaction effluent to at least one of (i) contacting with a xylene isomerization catalyst, (ii) transalkylation with at least one C
