Hydrocarbon dehydrocyclization in the presence of carbon dioxide

A hydrocarbon conversion process, comprising:

• (a) providing a feed comprising ≧1 wt. % of C2+ non-aromatic hydrocarbon and ≧0.1 wt. % of CO2;
• (b) providing first and second catalysts, wherein
• the first catalyst includes (i) ≧0.005 wt. % of a dehydrogenation component which comprises one or more of Ga, Zn, Mo, W, La, Pt, and Pd, and (ii) ≧10 wt. % of a molecular sieve component, the molecular sieve component comprising at least one molecular sieve having a Constraint Index in the range of from 1 to 12, and
• the second catalyst includes ≧0.005 wt. % of a CO2 conversion component which comprises one or more of Ru, Rh, Ni, Co, and Fe;
• (c) exposing the feed to the first catalyst under conversion conditions effective for (i) converting ≧10 wt. % of the feed's C2+ non-aromatic hydrocarbon to aromatic hydrocarbon and molecular hydrogen and (ii) increasing aromatic hydrocarbon yield by reacting ≧1 wt. % of the feed's CO2 with at least a portion of the molecular hydrogen in the presence of the second catalyst to produce methane and water.
