Regenerable catalysts for the conversion and oligomerization of hydrocarbons, e.g. methane, to produce products containing ethylene and/or benzene, comprise (1) a Group VIII noble metal having an atomic number of 45 or greater, nickel, or Group I-B noble metal having an atomic number of 47 or greater; (2) a Group VI-B metal oxide which is capable of being reduced to a lower oxide, or admixture of metal oxides which includes one or more of such metal oxides; and, (3) magnesium, strontium or barium, composited with a spinel-coated refractory support, notably an inorganic oxide support, or calcium composited with a non-zinc containing spinel-coated refractory support; preferably alumina. |
