本文研究了硫化态和还原态ＲｈＭｏＫ／Ａｌ２Ｏ３催化剂上ＣＯ加氢合成低碳醇的反应性能，考察了不同铑负载量、钾助剂、合成气组成和反应条件（温度、压力和空速）对合成醇性能的影响及催化剂的反应稳定性。发现硫化态样品较之还原态样品具有更好的合成醇选择性，催化剂中添加铑后，生成醇（特别是Ｃ２＋醇）活性和选择性大幅度提高。选择合适的反应温度、提高反应压力和空速、适当增加合成气Ｈ２／ＣＯ的比例可以获得较好的合成醇反应性能。
In this paper, the reactivity of CO by hydrogenation on the synthesis of lower alcohols over sulfided and reduced RhMoK / Al2O3 catalysts was investigated. The effects of rhodium loading, potassium promoter, syngas composition and reaction conditions (temperature, pressure and space velocity) The effect of the synthetic alcohol and the reaction stability of the catalyst. It was found that the sulfated samples had better synthetic alcohol selectivity than the reduced samples, and the activity and selectivity of alcohol (especially C2 + alcohol) increased greatly after rhodium was added to the catalyst. Choosing the appropriate reaction temperature, increasing the reaction pressure and space velocity, and properly increasing the ratio of H2 / CO in the syngas can obtain a better reaction performance of the synthetic alcohol.
