基于甲烷化反应的催化剂颗粒设计与过程强化
Process intensification and catalysts particle design for CO methanation
摘要
Abstract
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 techniquesvia fluidized bed reactors.关键词
