cu-mn-zn/y直接合成二甲醚催化剂中锌和锰的协同调节作用
, PP. 350-353
Keywords: 一氧化碳加氢,二甲醚,cu-mn-zn/分子筛,催化剂
Abstract:
？通过对y型分子筛负载cu-mn、cu-zn和cu-mn-zn催化剂的结构、表面性质及其直接合成二甲醚反应活性的对比,发现mn和zn对催化剂还原性能的影响作用相反,对催化剂吸附h2和co的影响也不同。mn和zn的单独添加或共同添加引起催化剂结构和组分之间相互作用程度的改变,是造成催化剂活性和选择性变化的主要原因。两者的协同作用,能调整催化剂的还原性能和吸附性能达到适合的状态,从而使得催化剂具有高的二甲醚合成活性。
