NANOCATALYSTS, PREPARATION METHODS AND APPLICATIONS FOR REFORMING CARBON DIOXIDE AND METHANE TO SYNGAS

摘要

The catalyst in this present application includes a support and an active component dispersed on/in the support; wherein the support is at least one selected from inorganic oxides and the support contains macropores and mesopores; and the active component includes an active element, and the active element contains an iron group element. As a high temperature stable catalyst for methane reforming with carbon dioxide, the catalyst can be used to produce syngas, realizing the emission reduction and recycling utilization of carbon dioxide. Under atmospheric pressure and at 800° C., the supported metal catalyst with hierarchical pores shows excellent catalytic performance. In addition to high activity and good selectivity, the catalyst has high stability, high resistance to sintering and carbon deposition.
