在一般金属催化剂上,由CO和H_2选择合成高级醇是合成气化学的重要研究方向。IFP在1982年提出的Cu-Co催化剂至今还是重要的体系,对合成C_2醇有较好的选择性,但这类催化剂存在热稳定性差、活性低的缺点,为改善催化剂的性质需添加热稳定性高的载体和助剂。有关Cu-Co催化剂体系的研究已有不少报道,但加入第Ⅲ组分对其性质的影 In general metal catalysts, the synthesis of higher alcohols from CO and H 2 is an important research direction of syngas chemistry. The Cu-Co catalyst proposed by IFP in 1982 is still an important system so far and has a good selectivity for the synthesis of C2 alcohols. However, such catalysts have the disadvantages of poor thermal stability and low activity, and need to be added to improve the properties of the catalyst High carrier and additives. There have been many reports about the Cu-Co catalyst system, but the influence of adding the third component on its properties
