An energy efficient and safe conversion of methane to syngas is possible by carrying out the exothermic oxidation of methane and the endothermic reaction of methane with steam and CO 2 simultaneously with the same NiO/CaO catalyst. By coupling the two reactions and manipulating the relative concentrations of CH 4 , O 2 , CO 2 , and steam in the feed, the overall methane‐to‐syngas conversion can be made mildly exothermic, thermoneutral, or mildly endothermic. The H 2 /CO ratio of the product can be varied from roughly 1.5 to 2.5.
