摘要
综述了加氢脱硫催化剂载体的研究现状及其发展趋势,分别从单组分载体、复合氧化物载体、分子筛和改性载体4个方面论述了加氢脱硫催化剂载体各自的优缺点。单组分载体重点介绍了A12O3、TiO2、炭载体;复合氧化物载体主要对铝基、钛基二元复合氧化物以及三元复合氧化物载体进行了综述;并且对以MCM-41、SBA-15和KIT为代表的介孔分子筛做了介绍;还描述了近年来以改性MCM-41、SBA-15、活性炭为主要研究对象的改性的分子筛。最后指出改性载体尤其是改性分子筛将是未来研究的焦点。
The research status and development tendency of hydrogenation desulfurization （HDS） catalyst support was outlined regarding the issue of high sulfur content in oil products. The development of HDS catalysts was reviewed in four aspects：single-component support,mixed oxide support,molecular sieve and modified support. Single component support,which laid emphasis on Al2O3,TiO2 and carbon support,was introduced in HDS reaction. Besides,mixed oxide support, which mainly includes aluminum-based,titanium-based binary mixed oxide support and ternary mixed oxide support,was summarized. Furthermore,molecular sieve was discussed,including MCM-41, SBA-15 and KIT. Ultimately,modified support,which contains modified MCM-41,modified SBA-15, modified carbon and other modified molecular sieve,was reported emphatically. In the future,modified supports,especially modified molecular sieves,will be paid increasing attention in the field of catalyst supports for HDS.
