以ZSM - 5分子筛为载体用浸渍法混合负载Cu、Ce ,研制出一种复氧化物分子筛催化剂MxOy/ZSM - 5(Cu、Ce) .考察了它对液相合成乙酸丁酯反应的催化活性 ,并探讨了催化剂的制备条件对催化活性的影响 ,用IR、DTA、TG、ICP、比表面仪等技术对催化剂进行表征 .结果表明 :在Cu∶Ce =3∶1,T =12 0℃ ,酸∶醇 =1∶2 ,催化剂用量为 3g ,t =6h时 ,乙酸丁酯的产率高达 96 % ,且催化剂制备成本低 ,催化剂热稳定性好 .
A zeolite complex catalyst MxOy / ZSM - 5 (Cu, Ce) was prepared by impregnation with Cu and Ce supported on ZSM - 5 zeolite by impregnation method. The catalytic activity of the catalyst for liquid phase synthesis of butyl acetate , And the effects of preparation conditions on the catalytic activity were discussed. The catalysts were characterized by means of IR, DTA, TG, ICP and specific surface area analyzer. The results showed that when the Cu: Ce = 3: 1, T = 120 ℃ , Acid: alcohol = 1: 2, the amount of catalyst 3g, t = 6h, the yield of butyl acetate up to 96%, and the preparation of low cost catalyst, catalyst thermal stability.
