摘要： 通过羰基钼和升华硫反应制备了晶片层数为3~5, 比表面积为 71 m2/g 的纳米 MoS2 催化剂, 并考察了其催化十二硫醇或二苯并噻吩的加氢脱硫活性. 结果表明, 在 3.0 MPa 初始氢气压力下, 该催化剂在 200 oC 和 280 oC 就可使十二硫醇和二苯并噻吩转化接近 100%.

Abstract: The MoS2 nanocatalyst of 3–5 layers and surface area as high as 71 m2/g was synthesized via a chemical reaction between molybdenum carbonyl and chalcogen. The hydrodesulfurization (HDS) of n-dodecanethiol and dibenzothiophene (DBT) was studied over the MoS2 nanocatalyst. Compared with the commercial MoS2 with lower surface area of 3 m2/g, the MoS2 nanocatalyst showed much higher activity. 100% conversion in HDS at temperatures of 200 °C for dodecanethiol and 280 °C for DBT was achieved under p(H2) = 3.0 MPa.
