钾和钴对微波法制备钼基催化剂的改性作用
, PP. 1115-1120
Keywords: 微波,mo基催化剂,助剂k,助剂co,低碳醇
Abstract:
？在微波辐射下制备了cox-mos3-ky/γ-al2o3催化剂,考察了催化剂中k和co的含量对其催化co加氢合成低碳醇性能的影响。结果表明,添加适量的k和co可以形成k-mo-s相和co-mo-s相,改善催化剂性能的同时还可以避免活性组分的集聚及载体孔道的堵塞;k/mo物质的量比为1.0,co/mo物质的量比为0.2时,有利于生成低碳混合醇,尤其是c2+醇。co转化率为38.4%,总醇的收率为5.65%,c2+oh的选择性为80.5%。
