Abstract

The invention relates to a metal-phase carrier loaded catalyst as well as a preparation method and application of catalyst in preparation of methane and methane synthesized gas reaction by catalyzing carbon oxide or (and) carbon dioxide. The metal-phase carrier loaded catalyst comprises active component metal oxide which is loaded on a metal-phase carrier and auxiliary metal oxide, the general formula of the metal-phase carrier loaded catalyst is as follows: xM1O-yM2O / ZT, wherein M1O represents the active component metal oxide, M2O represents the auxiliary metal oxide, ZT represents the metal-phase carrier, x represents the mass percent of the active component metal oxide in the catalyst, and y represents the mass percent of the auxiliary metal oxide in the catalyst. The catalyst has the advantages of high activity, high stability, excellent heat conduction property, high permeability, convenience in use, long service life, simplicity in preparation and the like, the heat effect difficulty in strong heat discharging / suction reaction in the chemical industry field can be effectively solved, and the catalyst can be used in the methanation process and the methane-producing synthesized gas reaction.

Description

technical field [0001] The invention belongs to the technical field of catalysis, and relates to a catalyst and its preparation method and application, in particular to a catalyst supported by a metal phase and its preparation method and application. The catalyst can be used to catalyze the addition of carbon monoxide or (and) carbon dioxide Hydrogen reacts in the synthesis of methane and reforming of methane to synthesis gas. Background technique [0002] Natural gas is a safe, clean and high-quality energy, the main component of which is methane (CH 4 ), has the advantages of high calorific value and low pollution, and is widely used in power generation, chemical industry and civil use. Since Sabatier and Senderens first used carbon monoxide and hydrogen to synthesize methane on a nickel-based catalyst in 1902, the methanation reaction has developed rapidly and has been widely used in gas purification processes. [0003] The key to the methanation process is the developm...
