  • Patent number: 5204308
    Abstract: An anionically stabilized lithium catalyst wherein the anion is sulfate, phosphate, aluminate, silicate and mixtures thereof. The anionically stabilized lithium catalyst may be supported on a metal oxide support of magnesium oxide, titanium oxide, zinc oxide, calcium oxide, barium oxide, strontium oxide, zirconium oxide, hafnium oxide, yttrium oxide, lanthanum oxide, samarium oxide, and mixtures thereof or when aluminate or silicate is used as the anion the aluminate or silicate may act as the support. The catalyst may be used to promote reactions at temperatures higher than prior lithium catalysts, particularly higher than about 600.degree. C., such as oxidative coupling of aliphatic and alicyclic hydrocarbons to produce higher molecular weight compounds and oxydehydrogenation of aliphatic and alicyclic hydrocarbons to produce unsaturated hydrocarbons or to change the functional group of the hydrocarbon.

  • Patent number: 4956327
    Abstract: A mixed basic metal oxide/sulfide catalyst having the formulaxA.yB.zC.qDwherein A is an alkali metal selected from lithium, sodium, potassium, rubidium, cesium and mixtures thereof; B is a cation which has an ionization state 2 and 3 greater than the ionization state of C; B is selected from titanium, zirconium, hafnium, tantalum, niobium, vanadium and mixtures thereof; C is selected from magnesium, calcium, strontium, barium and mixtures thereof; D is selected from oxygen, sulfur and mixtures thereof; x and y are in mole fractions of z such that when z=1 then x=0.001 to 0.25, and y=0.001 to 0.25; and q is a number necessary to maintain charge balance with D. The sulfide form provides tolerance for sulfur containing feedstocks. The catalyst is useful for oxidative coupling of methane and aliphatic and alicyclic hydrocarbon compounds with an aromatic compound to produce higher molecular weight hydrocarbons and for dehydrogenating hydrocarbon compounds to produce unsaturated aliphatic and alicyclic chains.
