| 摘 要： | 通过P改性对USY分子筛酸量进行调节,考察酸量对四氢萘选择性开环反应的影响。结果表明,P改性后USY分子筛弱酸量增加,中强酸略增,强酸基本不变,P_(0.5)-USY分子筛弱酸量增加有利于四氢萘生成不饱和开环产物。负载贵金属Pt后,Pt_(0.4)/P_(0.5)-USY催化剂上四氢萘转化率99.37%,开环选择性40.79%,贵金属Pt的引入对结焦前驱体的生成有抑制作用。

| Abstract: | The acidity of USY zeolite was adjusted by modification of phosphorus to investigate activity for selective ring-opening reaction of tetralin.Results showed that weak acid content of USY zeolite increased after introduction of phosphorus,medium acid content slightly increased and strong acid basically unchanged.P0.5-USY catalyst with more weak acid content was more favorable for tetralin to form unsaturated ring opening products.Conversion of tetralin was 99.37%,selectivity of ring opening was 40.79% over Pt0.4/P0.5-USY catalyst.Additon of Pt could inhibit formation of coking precursor. |
