A catalyst composition and process facilitates the oxidative reforming of low molecular weight hydrocarbons, such as methane, to other hydrocarbons having 2 or more carbon atoms ('Ccompounds'). Compositions having a formula comprising a metal, 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 produced favorable yields of Ccompounds, 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.

Catalyst and method for converting natural gas to higher carbon compounds

The invention relates to ZrB.sub.2 /Cu composites, and more specifically to methods of making ZrB.sub.2 /Cu composite electrodes and methods of using ZrB.sub.2 /Cu composite electrodes. ZrB.sub.2 powder is contacted with a polymer and shaped to a desired form. The polymer is vaporized and the ZrB/.sub.2 powder is sintered. The sintered ZrB.sub.2 is contacted with Cu and heated above the melting point of Cu which causes the Cu to infiltrate the ZrB.sub.2, forming the ZrB.sub.2 /Cu composite electrode.
