摘要
制备了不同镓含量的镓皂石层柱材料,用XRD、NH3-TPD表征了样品的晶相、酸性,考察了样品对β-甲基萘歧化反应的催化性能.结果表明:β-甲基萘在含镓层柱材料上以异构反应为主,活性与酸量、选择性与酸性有很好的对应关系.氧化铝交联皂石与氧化镓交联皂石相比较,活性与歧化选择性高,但异构选择性低.
Pillared materials with gallium are synthesized and characterized. The catalytic properties of disproportionation reaction of β- methylnaphthalene are observed, the results show that isomerization of β- methylnaphthalene is the main reaction. The activity and selectivity have good relation to acid amount and acid properties. The activity of cross - linked Ga - substitued saponite isbigger, and the selectivity of disproportionation is also bigger. However, the selectivity of isomerization is smaller.
