To provide a catalyst composition and process that facilitate the oxidative reforming of low molecular weight hydrocarbons, such as methane, to other hydrocarbons having 2 or more carbon atoms ("C2 compounds").
Compositions having a formula comprising a tungsten, manganese and oxygen effectively catalyze the oxidative reforming of methane with a high rate 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 system can be utilized for the oxidative reforming reactions. Using two reactors in series, catalyst embodiments produce 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 reactor effluent, followed by recycling of the residual effluent, increases the conversion to, and ultimate yield of desirable end product.
