【摘要】 研究了贵金属钯基催化剂在重整生成油选择性加氢脱烯烃反应中的性能,考察了载体焙烧温度、活性金属含量、Pd与助剂配比对催化剂活性和选择性的影响,并对本研究的最佳催化剂(UDO-01)进行了600h的稳定性试验。实验结果表明,采用700℃的载体焙烧温度、活性金属总量0.2%(w)、Pd/M为2:1(摩尔比)的条件,制得的催化剂具有良好的加氢活性和选择性;在重整生成油全馏分加氢600h的试验运转过程中,产品油的溴值始终小于200mgBr/100g油,且芳烃损失小于0.5%(w)。更多还原

【Abstract】 The hydrogenation performance for reformate over noble Pd-based catalysts which supported on alumina was researched. The main factor influenced on catalyst reactivity and selectivity, such as calcination temperature, active metal component content and Pd/promoter molar ratio were studied. 600-hour running for stability was carried out. It was found that catalyst have best hydrogenation activity and selectivity under 700℃ calcination temperature of support with the total mass fraction of palladium and promoter was 0.2% and mol ratio was 2∶1 were suitable. The result of 600-hour running for stability to whole reformate shown that the bromine value of product was lower than 200 mgBr/100g oil and the loss of aromatics was less than 0.5% (mass fraction).更多还原
