PREPARATION METHOD AND APPLICATION METHOD OF NI-CO BIMETALLIC CATALYST FOR DRY REFORMING OF METHANE
A preparation method and an application method of a NiCo bimetallic catalyst for dry reforming of methane are provided, which relate to the field of catalytic material preparation technologies. The preparation method uses Ni and Co as active components of a catalyst for dry reforming of methane, alkaline earth metal salt as CO.sub.2 adsorbent, and uses an immersion method to prepare a NiCo bimetallic catalyst with high performance. The prepared catalyst not only effectively overcomes a problem of poor stability of Ni-based catalysts, but also promotes the adsorption of CO.sub.2 and improves the efficiency of dry reforming of methane. The preparation method of the NiCo bimetallic catalyst is simple and cost-effective, and exhibits excellent catalytic performance and stability in dry reforming reaction of methane.
DRY REFORMING CATALYST USING METAL OXIDE SUPPORT, AND METHOD FOR PREPARING SYNTHETIC GAS BY USING SAME
The present invention relates to a dry reforming catalyst in which an active material is impregnated on the surface of a metal oxide support and the active material is surrounded by a surfactant, a method of preparing the same, and a method of producing a synthetic gas using the catalyst. Since the surfactant on the surface of the active material prevents the active material from being sintered and the active material surface from being covered with carbon, the dry reforming catalyst exhibits high activity at high temperature for a long period of time without having to use a precious metal, and thus is useful for the production of a synthetic gas.
NANOCATALYSTS, PREPARATION METHODS AND APPLICATIONS FOR REFORMING CARBON DIOXIDE AND METHANE TO SYNGAS
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.
