用Ｃｕ（ＮＯ３）２对载体（γ－Ａｌ２Ｏ３）表面修饰后制成的负载型双金属铜促进催化剂进行了ＣＯ加氢反应研究。与未促进催化剂对比，铜助剂对生成低碳烃和提高ＣＯ转化率均有较强的促进作用。在２８０℃时，铜促进催化剂对生成低碳烃的选择性可达５９．４％，突破了Ｓｃｈｕｌｚ－Ｆｌｏｒｙ产物分布规律的限制。同时，还研究了铜促进催化剂的活性和选择性随反应温度、时间的变化规律。等离子发射光谱（ＩＣＰ）对铜促进催化剂的表征结果显示，铜促进催化剂有较高的金属（Ｆｅ＋Ｃｏ）负载量。
The CO hydrogenation of supported bimetallic Cu-promoted catalysts prepared by surface modification of Cu (NO3) 2 on γ-Al2O3 substrates was studied. Compared with uncatalyzed catalysts, copper promoters have a strong role in promoting the formation of low-carbon hydrocarbons and increasing the CO conversion. At 280 ℃, the selectivity of copper promoted catalyst to produce lower hydrocarbons reached 59.4%, which broke the restriction of Schulz-Flory product distribution. At the same time, the activity and selectivity of copper promoted catalysts with the reaction temperature and time were also studied. Characterization of the copper promoted catalyst by plasma emission spectroscopy (ICP) showed that the copper promoted catalyst had a higher metal (Fe + Co) loading.
