摘要
用一步并流共沉淀法制备了Cu/Zn/Al,Cu/Zn/Mn及Cu/Zn/Al/Mn系甲醇合成催化剂,并对它们的结构和性能进行了对比研究。研究结果表明,Cu/Zn/Al/Mn系催化剂活性较高且活性温区较宽,说明铝、锰组份之间具有协同促进作用。
Cu/Zn/Al, Cu/Zn/Mn and Cu/Zn/Al/Mn catalysts for methanol synthesis have been prepared by onestep parallelflow coprecipitation, and their structures and properties also investigated. The results show that the Cu/Zn/Al/Mn catalyst has higher catalytic activity and wider range of working temperatures, indicating a synergetically promoting interaction between the aluminium and manganese components.
