Abstract
Processes for the conversion of hydrocarbons, and most preferably methane, to higher hydrocarbons and olefins are disclosed, including contacting the hydrocarbons with a mixed metal oxide catalyst having the pyrochlore structure. Preferably, these catalysts have the general formula A.sub.n B.sub.2 O.sub.7-x, where A can be various mono-, di-, and trivalent metal cations, B can be various tri-, tetra-, penta-, and hexavalent metal cations, 0.ltoreq.n.ltoreq.2.0, and 0.ltoreq.x.ltoreq.1.0. Novel, high surface area, mixed metal oxide catalysts having the pyrochlore structure are also disclosed, including those having the formula A.sub.2 B.sub.2 O.sub.7, where A is divalent and B is niobium and/or tantalum, and those having the formula A.sub.2 (Sn.sub.2-y A.sub.y)O.sub.7-z, where A is bismuth and/or lead, 0.0.ltoreq.y.ltoreq.1.0, and 0.0.ltoreq.z.ltoreq.1.0.
