摘要
介绍了预硫化反应机理,综述了器内和器外预硫化技术的发展现状。结果表明:器外预硫化技术具有开工时间短,环境污染少的优点,已成为加氢催化剂预硫化的主要技术;未来,器外加硫完全活化技术将成为加氢催化剂预硫化发展的重要方向。
The presulfurization reaction mecha- nism was introduced and the present development situation of in - situ and ex - situ presulfurization technology were reviewed with 33 references. The re- sults showed that the ex - situ presulfurization tech- nology became the main technology of hydrogenation catalyst presulfurization,because of its advantages of short starting time and less environmental pollution. In the future,the ex- situ resulfurized and fully ac- tivated technology would become the important de- velopment direction of hydrogenation catalyst presul~ furization.
