Abstract: An improved process for the production of synthesis gas (or carbon monoxide and hydrogen) by oxidative conversion of natural gas or methane, which comprises passing continuously a gaseous reactant mixture comprising methane (or natural gas) and oxygen (or air) with or without water vapors over reduced or unreduced composite catalyst, containing non-transition and/or transition metal oxides, represented by the formula T.sub.m.N.sub.n.R.O.sub.p, wherein T is selected from Ni, CO, Ir or the like or a mixture thereof, m is T/R mole ratio, N is a transition or non-transition element selected from Ti, Zr, Hf, Zn, Mg, Ca or the like or a mixture thereof, n represents the N/R mole ratio, R is a rare earth element selected from La, Ce, Pr, Ho, Yb or the like, or a mixture thereof, O is oxygen and p is the number of oxygen atoms required to fulfill the valence requirement of the elements in the composite catalyst.
