Catalyst for preparing synthesis gases through methane carbon dioxide reforming (DMR) and preparation method thereof

The catalyst preparation method and carbon dioxide reforming of methane to syngas, belonging to the technical field Carbon Dioxide Reforming of Methane to Synthesis Gas. The catalyst of the present invention is composed of nickel, iron, cerium oxide, spinel Alcoa; method of the present invention is a hole MgAl2O4 spinel carrier medium is first prepared and then the preparation of nickel-based catalyst suspension was finally filtered, washed, dried, calcined simple process to obtain the finished product. The present invention employs a nickel, iron and other non-noble metal material, widely available, low cost; method of the present invention has simple process, simple equipment and low production cost; high catalytic activity of the prepared product, high conversion of methane and carbon dioxide; Coking Resistant and good stability. The present invention can be widely used as methane, carbon dioxide reforming catalyst of the synthesis gas.
