Catalysts comprising lead doped zirconium compounds are particularly effective in an oxidative process for upgrading low molecular weight alkanes to higher molecular weight hydrocarbons, and especially for upgrading methane to form ethane and ethylene. The catalysts can be employed in a process performed at elevated temperatures and in the presence or absence of gaseous oxygen. The catalysts are substantially free of PbO and uncombined Pb and remain stable for long periods of time.

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.
