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。
The recent progress of mesoporous catalysts supported on mesoporous molecular sieves and mesoporous Al2O3 in olefin disproportionation is reviewed, including the synthesis of mesoporous supports, the preparation of mesoporous catalysts and their applications in olefin disproportionation Mesoporous catalyst development prospects. The tungsten-based and molybdenum-based catalysts supported on mesoporous molecular sieves and the rhenium-based and molybdenum-based catalysts supported on mesoporous Al2O3 usually exhibit higher disproportionation of olefins than the corresponding catalysts supported on common SiO2 and Al2O3 Activity and selectivity as well as longer service life.
