一步法催化乙醇合成正丁醇

Catalyzing of Ethyl Alcohol into N-butyl Alcohol by One-step Method

以Mg O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。

Taking Mg O 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 flow rate is 3.0-4.0 L/h.
