摘　　要：过渡金属硫化物催化剂广泛应用于石油炼制催化加氢过程。催化剂活性相的结构与加氢脱硫性能的关系一直是催化研究的热点。放射性^(35)S同位素示踪技术由于能够在线分析硫化态催化剂上硫的性能而备受关注。综述了放射性^(35)S示踪技术在辅助研究加氢脱硫催化剂预硫化过程、加氢脱硫反应机理及催化剂上硫的性能中的应用。Transition metal sulfide catalysts are relationships between catalyst structure and the applied in petroleum refining processes widely. The hydrodesulfurization （HDS） properties has been the hotspots of the catalysis research. Much attention has been focused on ^35S radioisotope tracer techniques because they can directly estimate the behavior of sulfur in working catalysts on-line. The application of auxiliary research on presulfurization process, HDS reaction mechanism and the behavior of sulfur in sulfided catalysts using ^35S radioisotope tracer techniques were reviewed.
