研究了碱金属离子(Li~+、Na~+、K~+、Cs~+)和碱土金属离子(Ca~(2+)、Sr~(2+)、Ba~(2+))为助剂的硫化MoO_3/ZrO_2催化剂上CO加氢合成低碳混合醇的反应性能。碱金属离子(Li~+,K~+)、特别是钾离子为助剂的催化剂比之碱土金属离子助剂具有更好的合成低碳醇的活性和选择性。从一系列的实验和分析发现,硫化K-MoO_3/ZrO_2的合成低碳醇的活性和选择性强烈依赖于钾助剂的含量和反应条件。合理选择最佳K/Mo比(～0.5原子比)、反应压力、温度和空速可以获得较好的合成醇活性和选择性。
Alkali metal ions (Li ~ +, Na ~ +, K ~ +, Cs ~ +) and alkaline earth metal ions (Ca ~ (2+), Sr ~ (2+), Ba ~ Reactivity of CO Hydrogenation to Synthesis of Low Carbon Mixed Alcohols over Sulfided MoO_3 / ZrO_2 Catalyst. Alkali metal ions (Li ~ +, K ~ +), especially potassium ions as a promoter, have better activity and selectivity for synthesis of lower alcohols than alkaline earth metal ion additives. From a series of experiments and analysis, it was found that the activity and selectivity of sulfurated K-MoO 3 / ZrO 2 for synthesis of lower alcohols are strongly dependent on the content of potassium aids and the reaction conditions. Reasonable choice of the best K / Mo ratio (~ 0.5 atomic ratio), reaction pressure, temperature and space velocity can obtain better synthetic alcohol activity and selectivity.
