摘要: 考察了不同柱高、柱密度及柱含量的铝镓交联层柱对β-甲基萘的催化行为.结果表明,β-甲基萘主要以异构化为主,活性与酸量、异构化选择性与弱酸量、歧化选择性与L酸量均有很好的对应关系.柱高度降低及柱密度的增加均有利于2,6-二甲基萘的生成.

关键词: 层柱材料, &beta, -甲基萘, 择形性

Abstract: The catalytic reactions of β-methylnaphthalene(β-MN) were carried out over the prepared pillared materials with different pillar height, pillar density and content in the layer and pillar.The results show that β-MNis mainly converted to a-MNby isomerization over the samples.The activity and selectivity of isomerization and disproportionation have good relation to acid amount, weak acid amount and Lacid amount, respectively.Low pillar height and high pillar density are in favour of the formation of 2,6-DMN.

Key words: Pillared material, β-methylnaphthalene, Shape selectivtiy
