摘要：
A method for producing C
2+ hydrocarbons and H
2 comprising (a) introducing to a reactor a reactant mixture comprising methane, (b) heating the reactant mixture to a preheating temperature to yield a heated mixture, (c) generating free radicals in the heated mixture to form a primary effluent mixture comprising free radicals, C
2+ hydrocarbons, H
2 , and unreacted methane, (d) reacting the primary effluent mixture in a secondary reaction zone to form a secondary effluent mixture comprising C
2+ hydrocarbons, H
2 , free radicals, and unreacted methane, at a secondary reaction zone temperature that is greater than the preheating temperature, wherein a free radicals amount in the primary effluent mixture is greater than a free radicals amount in the secondary effluent mixture, (e) cooling the secondary effluent mixture to a quench temperature lower than the secondary reaction zone temperature to yield a product mixture comprising C
2+ hydrocarbons and H
2 , and (f) recovering the product mixture.
