摘    要:碳纳米管负载的Mo-Co-S加氢脱硫催化剂,其对噻吩的HDS在一定的反应条件下显示出比常规载体γ-Al2O3或SiO2负载催化剂更高的催化活性;从能谱(XPS)表征的角度研究探讨了该类催化剂反应活性高的原因,并结合H2-TPR,H2-TPD等谱学表征的结果,讨论了CNTs载体的促进作用本质.

关 键 词:HDS  Mo-Co-S  碳纳米管  XPS

Abstract:With a type of home-made multi-walled carbon nanotubes(CNTs) as support,CNT-supported Mo-Co-S catalysts,symbolized as x%(mass percentage)MoiCoj/CNT,were prepared by an incipient wetness technique.It was experimentally found that using the CNTs in place of γ-Al2O3 or SiO2 as support of the catalyst led to a significant increase in concentration of catalytically active Mo-species(Mo(4+)) at the surface of the functioning catalyst.This unique feature would be beneficial to generating microenvironments with higher Mo(4+) concentration of these kind of catalysts on the surface of the functioning catalyst,and thus be favorable to increasing the rate of the thiophene HDS reaction.
Keywords:XPS  multi-walled carbon nanotubes  CNT-supported Mo-Co-S catalyst  thiophene HDS
