Progress in Ni-Based Catalysts for CO Methanation
Author(s): 
Pages: 340-345
Year: Issue:  3
Journal: Petrochemical Technology

Keyword:  镍基催化剂一氧化碳甲烷化载体催化机理;
Abstract: 综述了国内外CO甲烷化催化剂的研究现状,重点介绍了CO甲烷化Ni基催化剂的载体、助剂和催化机理等方面的研究进展.关于载体的研究由Al2O3转向ZrO2,助剂从碱土金属和稀土金属向过渡金属元素转变,并在催化机理的研究中引入密度泛函理论,考察反应过程中生成的活性中间物种对催化活性的影响,以期改进这类催化剂,促进其工业应用.以新型载体负载Fe等多金属催化剂将是未来CO甲烷化催化剂发展的新方向.
