High-temperature, attrition resistant, oxidation catalysts are disclosed. These catalysts are represented by the formula

Oxidation catalyst and processes using same

A process for converting a gaseous reactant comprising methane or natural gas to higher molecular weight hydrocarbon products is disclosed which comprises: (1) contacting said gaseous reactant with an oxidative coupling catalyst at a reaction temperature in the range of about 500.degree. C. to about 1100.degree. C. for an effective period of time to form an intermediate product comprising ethane, ethylene or a mixture thereof; and (2) pyrolyzing said intermediate product at a temperature in the range of about 900.degree. C. to about 1500.degree. C. for an effective period of time to form said higher molecular weight hydrocarbon products.

Process for upgrading light hydrocarbons using oxidative coupling and

Oxidation catalyst amended by examiner

A process is disclosed for converting a gaseous or vaporized hydrocarbon feedstock to a product comprising ethylene, acetylene or a mixture thereof. The process comprises the steps of advancing a gaseous or vaporized stream comprising a gaseous or vaporized fuel and an oxygen source into contact with particulate solids in one section of an annular gas-solids contacting zone, said stream being deflected at the entrance to said one section of said contacting zone sufficiently to move said solids in a generally circumferential and horizontal direction, said particulate solids being at a sufficiently high temperature to effect combustion of said gaseous fuel, said particulate solids comprising an effective amount of at least one oxidation catalyst to enhance the combustion of said fuel, combusting said gaseous fuel, the heat from said combustion heating said solids, and removing a gaseous or vaporous material comprising exhaust gases or vapors from said combustion from said one section of said contacting zone; moving said particulate solids to another section of said contacting zone, the movement of said solids being effected by the flow of said gaseous stream, advancing said feedstock into said another section of said annular contacting zone into contact with said particulate solids, said feedstock being deflected at the entrance to said another section of said contacting zone sufficiently to move said solids in a generally circumferential and horizontal direction, converting at least some of said feedstock to said product, and removing said product from said another section of said contacting zone; and returning said particulate solids to said one section of said contacting zone. The resulting product can then be converted to higher order hydrocarbons, especially substantially liquid hydrocarbons.

High-temperature, attrition resistant, oxidation catalysts are disclosed. These catalysts are represented by the formula AMO.sub.w [(DO.sub.x)(EO.sub.y)a]z wherein A is an alkali or alkaline earth metal; M is V, Cr, Mo, Mn, Fe, Co, Ni, Cu or a mixture of two or more thereof; D is Zr, Ti, Hf, Ce, Th, Pr, Nb, Ta, W, Re or a mixture of two or more thereof; E is Ca, Mg, Sr, Ba, Y, La, Yb, Sm, Gd, Nd, Sc, V, Bi, Ce, Pr, Eu, Tb, Dy, Ho, Er, Tm, Lu or a mixture of two or more thereof; a is a number in the range of zero up to about 0.2; w is the number of oxygens needed to fulfill the valence requirement of AM; x is the number of oxygens needed to fulfill the valence requirements of D; y is the number of oxygens needed to fulfill the valence requirements of E; and z is a number in the range of about 10 to about 100. The invention further provides for the use of such catalysts in processes involving the combustion of organic materials (e.g., carbonaceous fuels, organic waste materials, etc.) and the autothermal pyrolysis of methane and/or natural gas.
