| 摘 要： | 主要介绍了近年来以介孔分子筛和介孔Al2O3为载体的介孔催化剂在烯烃歧化中的研究进展,包括介孔载体的合成、介孔催化剂的制备及其在烯烃歧化中的应用,并展望了介孔催化剂的发展前景。以介孔分子筛为载体的钨基和钼基催化剂以及以介孔Al2O3为载体的铼基和钼基催化剂在烯烃歧化反应中,通常表现出比以普通SiO2和Al2O3为载体的相应催化剂更高的活性和选择性以及更长的使用寿命。

| Abstract: | The recent progress in the heterogeneous catalysts with siliceous mesoporous molecular sieves or mesoporous alumina as supports for metathesis of olefins were reviewed,which included synthesis of the mesoporous supports,preparation of the catalysts and their application to the olefin metathesis.The future applications of the mesoporous catalysts to the olefin metathesis were discussed.The obtained results indicated that the siliceous mesoporous molecular sieves MCM-41,MCM-48,HMS and SBA-15 and mesoporous alumina supported WO3,MoO3 or Re2O7 catalysts usually exhibited considerably higher activity,selectivity and working life-span in the olefin metathesis than those of the corresponding catalysts based on conventional silica or alumina support. |
