A catalyst composition and process facilitates the oxidative reforming of low molecular weight hvdrocarbons, such as methane, to other hydrocarbon atoms having 2 or more carbon atoms (''C2 compounds.'') Compositions having a formula comprising a metal tungsten, manganese and oxygen effectively catalyze the oxidative reforming of methane with a high rale of conversion and selectivity. Controlling feed gas flow and catalyst bed temperature controls the exothermic OCM reaction, avoiding runaway reactions or coking. A single or multiple reactor svstem can be υtilized for the oxidative reforming reactions. Using two reactors in series, catalyst embodiments produced favorable yields of C2 compounds, in the presence or absence of a distributed oxygen feed, and with or without interstage effluent cooling. Removal of desirable end products from the reactor effluent, followed by recycling of the residual effluent, increases the conversion to, and ultimate yield of desirable end product. |
