A catalyst and process for formation of hydrocarbons having carbon numbers of two or greater, the result of both oxidative coupling of methane ("OCM"), and other reforming reactions of OCM end products. An OCM catalyst has a structure represented by formula ABTiO3, wherein A is samarium or tin, B is barium; the reforming catalysts a composition represented by formula XYZ, wherein X is a metal from Group IA, Group IIA or Group VIIIA, or not present, Y a metal from Group VA, Group VIA, Group VIIA or Group VIIIA, Z chosen from oxygen, silica, silicalite and alumina. The inventive catalyst comprises an OCM catalyst and a reforming catalyst blended together; when used in a reactor effects an increased yield of hydrocarbons having a carbon number greater than 2 (in excess of 27%-30%, first pass rate of methane conversion about 50%) than occurs under OCM conditions alone. |
