Catalyst Preparation Process
Catalyst carrier
The carrier of the catalyst used in the autothermal reforming of methane needs to have appropriate crystal phase composition, specific surface area and pore structure.In order to facilitate the adsorption and activation of reactant molecules on the catalyst surface.
At the same time, it is also conducive to the desorption of product molecules to leave the catalyst surface, so as to prevent the occurrence of carbon deposition reaction. In addition, the carrier should also have good mechanical strength.
Carrier Type
The acid base of the carrier surface
The oxygen storage capacity of the carrier
2.The active component of the catalyst
The catalysts used in methane oxidation and reformed gas reactions are mainly supported metal catalysts, and their metal active components are divided into two categories: noble metals such as Pd, Ru, Rh, Pt, Ir, etc. and non-precious metals such as Ni, Co, Fe, etc. Ⅷ Group transition metals.
