摘要
阐述了加氢催化剂预硫化原理,介绍了苯加氢催化剂预硫化技术的应用进展,预硫化技术主要包括器内预硫化和器外预硫化,重点说明了国内外器外预硫化技术的研究进展,器外预硫化具有开工时间短、投资少、环境污染小、硫化效果好、易于运输等优点,随着器外预硫化技术逐步走向成熟,器内预硫化将会被器外预硫化所取代。
The theory on presulfurization technology for hydrotreating catalyst was discussed.The application process in presulfurization technology for hydrogenation catalyst with adding benzene was introduced. The presulfurization technology was mainly composed of in-situ presulfurization and ex-situ presulfurization. The latest developments on ex-situ presulfuriztion technologies at home and abroad were particularly illustrated. The ex-situ presulfurization technology had the advantages such as short time in operation, low investment, low environmental pollution, good effect in carrying out sulfuration and transport facilitation. As the ex-situ presulfurization technology was increasingly ripe, the in-situ presulfurization operation would be replaced by ex-situ presulfurization.
