Abstract: A reactor (12, 128, 198) and method for the conversion of hydrocarbon gases utilizes a reactor (12, 128, 198) having a unique feed assembly (58, 136, 200) with an original vortex disk-like inlet flow spaces (72, 74, 76, 80, 146, 148, 150, 152, 208, 216, 218), a converging-diverging vortex mixing chamber (116), and a cylindrical reactor chamber (40). This design creates a small combustion zone and an inwardly swirling fluid flow pattern of the feed gases that passes through a converging conduit (48) with a constricted neck portion (54). This provides conditions suitable for efficient cracking of hydrocarbons, such as ethane, to form olefins.

Abstract: A method of selecting a stable mixed metal oxide catalyst for an oxidative coupling of methane (OCM) reaction is disclosed. The method may include, obtaining a mixed metal oxide material having catalytically active metal oxides for the OCM reaction and identifying the Tammann temperature (TTam) of at least one of the catalytically active metals oxides of the mixed metal oxide material. The method further includes selecting the mixed metal oxide material for use as a catalyst in the OCM reaction if the at least one catalytically active metal oxides present in the mixed metal oxide material has a TTam greater than a predetermined temperature.

Abstract: A method for producing C2+ hydrocarbons and H2 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, C2+ hydrocarbons, H2, and unreacted methane, (d) reacting the primary effluent mixture in a secondary reaction zone to form a secondary effluent mixture comprising C2+ hydrocarbons, H2, 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 C2+ hydrocarbons and H2, and (f) recovering the product mixture.
