| Abstract: | 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. |
