以MoO - 3和Co-Mo氧化物与n2 - h2反应制备了高比表面积的氮化钼（γ-Mo -N）和共促进氮化钼（Co-Mo-N）催化剂，并用XRD和BET对其进行了表征。二苯并噻吩（DBT）加氢脱硫-(HDS)的测定结果支持以下结论：(1)γ-Mo -N和Co-Mo-N对二苯并噻吩中C-S键断裂具有较高的HDS活性和选择性；(2)不同预处理条件对HDS活性和选择性的影响；(3) Co的加入显著提高了γ-Mo 2 N的HDS活性。
Molybdenum nitride (γ-Mo 2 N) and Co-promoted molybdenum nitrides (Co-Mo-N) catalysts with high surface area have been prepared from the reaction of MoO 3 and Co-Mo oxides with N 2 -H 2 and characterized by XRD and BET. The results of measurement of hydrodesulfurization-(HDS) of dibenzothiophene(DBT) supported the following conclusions: (1) γ-Mo 2 N and Co-Mo-N have higher HDS activity and selectivity for C-S bond breakage in dibenzothiophene; (2) different pretreatment conditions affect the HDS activity and selectivity; (3) the HDS activity of the γ-Mo 2 N is significantly improved with the addition of a Co promoter.
