苯选择加氢制环己烯Ru系催化剂的研究

A Study on Ru Catalysts for Selective Hydrogenation of Benzene to Cyclohexene

用化学还原法制备了苯选择加氢制环己烯Ru系催化剂 ,其中Ru为活性组分 ,Cu或其他金属作为助剂 ,ZrO2 为分散剂。研究了助剂Cu及其含量对反应活性及选择性的影响。结果表明 ,当Cu/Ru =1 5 %时 ,Ru -Fe -Cu -B/ZrO2 催化剂在苯转化率较高的情况下 ,环己烯的选择性也较高 ,该催化剂具有很好的工业应用前景。

Ru catalysts were prepared by chemical reduction method for selective hydrogenation of benzene to cyclohexene,in which Ru was an active component,Cu and other elements were promoters and ZrO 2 was used as a dispersant.The effect of Cu promoter on reactive activity and selectivity was studied.It showed that when Cu/Ru ratio was 1 5%,the benzene conversion and cyclohexene selectivity were both higher with Ru-Fe-Cu-B/ZrO 2 catalyst.The catalyst is of great prospect of industrial appliance.
