Additionally, methane synthesis gas is one of important channel realizing methane chemical utilization, steam reformation, portion are developed at present
Divide the process for preparing synthetic gas such as oxidation, CO 2 reformation and self-heating recapitalization, but above-mentioned technique all exists stronger heat effect (by force
Heat absorption or strongly exothermic) problem, the thermodynamic study for them shows, it occurs side reaction carbon distribution the most at low temperatures.Thing
In reality, owing in traditional fixed bed reaction pipe, effective heat transfer coefficient is the most relatively low, even if tube wall temperature is up to 800 DEG C, bed
Still suffering from cold spot in Ceng, carbon distribution is difficult to avoid that.
Metal phase carrier structure catalyst is owing to its specific surface area is big, the transmission advantages such as performance is good, bed pressure drop is low, at environment
Catalysis and Environmental capacity field have been applied.Utilize this excellent transmission performance, metal phase carrier structure catalyst is applied
In putting by force in chemical field/endothermic reaction, energy utilization efficiency can be increased substantially, it is achieved Process integration, reach
Purpose to process intensification.And all there is strong heat effect in methanation reaction, methane synthesis gas reaction, the most existing skill
Art has existed metal phase carrier structure methanation catalyst and the trial of methane synthetic gas catalyst.But, these are existing
The catalyst of technology exists that fusing point is low, chemism is high, catalysis activity is not enough, preparation is complicated, preparation process is polluted more serious
Etc. defect.
