一步法催化乙醇合成正丁醇

摘要

Taking MgO as the carrier and using the one-step method to steep the metals such as Ni , Ge , Pd etc. to prepare the catalyst, by which, it observes the reaction performance of catalyst by the ethanol homologous method to prepare butyl alcohol under different temperatur e and pressure. The results show that the selectivity of butyl alcohol can reach to 77 %, besides, the suitable reaction temperature is 280-320℃and the suitable reaction pressure is 2.8-3.5 MPa,The appropriate gas carrier lfow rate is 3.0-4.0 L/h.%以MgO为载体，通过一步法浸渍Ni、Ge、Pd等金属制备催化剂，考察了催化剂在不同温度、不同压力下乙醇同系化法制备丁醇的反应性能。结果表明，丁醇的选择性可以达到77%，适宜的反应温度为280-320℃，适宜的反应压力为2.8-3.5MPa，适宜的载气流速为3.0-4.0L/h。
