New Composite Materials Prepared by Solution Combustion Synthesis for Catalytic Reforming of Methane

Abstract

Processing of natural gas into motor fuel has become one of the major problems of chemistry. Partial oxidation and CO₂ reforming of CH₄ attract a great attention in recent years. Resistant to temperature extremes and thermal shocks is one of the most important requirements for catalysts. Works on research of intermetallic compounds as a contact mass for conversion of methane were carried out. Method of self- propagating high temperature synthesis was used for synthesis of catalysts. Investigation of the activity of catalysts based on the initial mixture of metal oxides produced in the solution combustion synthesis process was carried out in the reaction of carbon dioxide conversion and partial oxidation of methane. 100 % methane conversion at 750 °C was carried out on the catalyst, whereas the conversion of CO₂ reached 81.7 % at 900 ^oC. H₂ yield reached 99.2 %, yield of CO - 99.1 % in the ratio of H₂/CO = 1.2. Effective catalysts for the production of synthesis gas from methane have been developed.
