摘要

采用两步溶剂热法成功制备出Ni/Al2O3/C催化剂,并将其应用于催化CO甲烷化反应。与其他方法制备的催化剂相比,采用溶剂热法制备的催化剂六方片更薄,尺寸较为规整,镍的加入量对产物的组成和形貌有较大影响。在连续流动固定床装置上考察了镍加入量不同的催化剂对CO甲烷化反应的影响,并通过CO的转化率和甲烷的收率来评价其性能。

Abstract

Ultrathin Ni/Al2O3/C catalyst were successfully prepared through a simple two-step strategy,and its catalytic performance for methanation of carbon monoxide were discussed.Compared with other methods,the product synthesized with solvothermal method was ultra-thin and relatively uniform.The phase composition and morphology of as-obtained products were influenced by various amount of nickelous nitrate.Finally,different contents of nickel catalyst for methanation of carbon monoxide were investigated in a continuous flow fixed bed device,and its catalytic performance was evaluated through CO conversion rate and yield of methanation.
