Carbon deposition and sintering of metal particles are the two dominating reasons for deactivation of the methanation catalyst. Based on the strong exothermic reaction accompanied by a large decrease in mole number and methanation mechanism

from the perspective of the matching of catalyst and reactor

this paper summarizes the development of main CO methanation techniques

CO methanation catalysts

reaction mechanism of CO methanation and its process intensifications. Fluidized bed reactors have the advantages in preventing the carbon deposition and sintering of Ni catalysts. Thus

the design of wear-resistant

easy fluidized and low density catalyst structure particles that applicable to fluidized bed reactors should be a feasible way and the new direction for the development of methanation techniques via fluidized bed reactors.
