摘  要:介绍了器内预硫化和器外预硫化两种加氢催化剂预硫化技术,阐述了催化剂预硫化反应原理,并对硫化剂进行了比选,讨论了干法硫化和湿法硫化两种器内预硫化技术的特点。干法硫化技术主要适用于分子筛含量较高的加氢催化剂,而湿法硫化技术主要适用于加氢精制类催化剂。通过对比器内预硫化与器外预硫化技术的优缺点,并对国内外器外预硫化技术研究现状进行了综述,认为器外预硫化技术具有开工时间短、环境污染小等优点,必将逐渐替代现有的器内预硫化技术成为加氢催化剂预硫化的主要技术,将是加氢催化剂预硫化技术未来研究发展的方向。Two presulfurization technologies for hydrogenation catalyst are introduced.One is in-situ presulfurization technology,and the other is ex-situ presulfurization technology.The catalyst presulfurization reaction principle is expounded,and the vulcanizing agent is compared.The characteristics of dry sulfurization and wet sulfurization technologies are discussed,i.e.,dry sulfurization technology is mainly applied to high contain molecular sieve in hydrogenation catalyst,and wet sulfurization technology is mainly applied to hydrotreating catalyst.By comparing in-situ presulfurization and ex-situ presulfurization technology,research status on ex-situ presulfurization technology is summarized,i.e.,ex-situ presulfurization technology needs short starting period and leads less environment pollution,and it will replace existing presulfurization technology gradually and become a main presulfurization technology for hydrogenation catalyst.Ex-site presulfurization technology will be the focus of technical development for hydrogenation catalyst in the future.
