Oxidative Conversion of Methane into Syngas Using Porous Catalysts Prepared by Combustion Synthesis

Abstract:

Using the method of combustion synthesis, a series of porous cermet materials from nickel and oxides (such as NiO, MgO, Al₂O₃, ZrO₂, and rare-earth oxides) was synthesized. They investigated in terms of their application as catalysts of the reaction of oxidative coupling of methane into synthesis gas. It is found out that the composites containing about 50% (NiO + Ni) and a small amount (up to 5%) of Ce, La, Nd, and Pr-oxides at the temperature 830^оС ensure the conversion efficiency of methane within 92 ÷ 95% and the H₂/CO ratio 2.0 ÷ 2.1 in the reaction products. The data obtained suggest that the materials manufactured can be effectively used in the systems of syngas manufacturing (for the Fischer – Tropsch process) and in the production of hydrogen from natural gas.
