摘要

摘要: 对分层装填的Ni₂P//MoS₂催化剂上的二苯并噻吩加氢脱硫反应进行了研究。结果表明,分层装填的Ni₂P/Al₂O₃和MoS₂/Al₂O₃催化剂在二苯并噻吩加氢脱硫反应中存在氢溢流效应,氢溢流有助于提高MoS₂催化剂的活性位密度和加氢脱硫反应速率。由于Ni₂P比NiS_x具有更强的氢分子解离能力,Ni₂P//MoS₂催化体系的氢溢流因子略高于NiS_x//MoS₂;相对于NiS_x,Ni₂P对MoS₂催化剂是更好的助剂。

Abstract: The hydrodesulfurization of dibenzothiophene over physically separated Ni₂P//MoS₂ catalyst beds was investigated.The results indicated that the hydrogen spillover effect appears between the Ni₂P/Al₂O₃ and MoS₂/Al₂O₃ catalysts in the hydrodesulfurization reaction, which can significantly enhance the concentration of active sites and the hydrodesulfurization rate over the MoS₂ catalyst. The spillover factor on Ni₂P//MoS₂is slightly higher than that on NiS_x//MoS₂, due to the higher hydrogen dissociation activity of Ni₂P; as a result, Ni₂P is a superior promoter to NiS_x for the MoS₂ catalyst.
