    Using pure benzene as raw material for the evaluation of catalytic activity of MoS_2, the study of the poisoning effect of pyridine and the "nitrogen compounds" separated from diesel fraction of Shale oil on MoS_2 catalyst was carried out. The experiments show that when the MoS_2 catalyst is previously treated by pyridine or "nitrogen compounds" under high pressure at lower temperature(300℃), it loses its activity for the hydrogenation of benzene ring; while at higher temperature (420℃), in such case that the...

    Using pure benzene as raw material for the evaluation of catalytic activity of MoS_2, the study of the poisoning effect of pyridine and the "nitrogen compounds" separated from diesel fraction of Shale oil on MoS_2 catalyst was carried out. The experiments show that when the MoS_2 catalyst is previously treated by pyridine or "nitrogen compounds" under high pressure at lower temperature(300℃), it loses its activity for the hydrogenation of benzene ring; while at higher temperature (420℃), in such case that the nitrogen compounds can be completely hydrogenalyzed, therefore, the hydrogenating activity of MoS_2 catalyst remains unchanged after nitrogen compounds treatment, however, its isomerization and cracking activities are somewhat poisoned. Among these the isomerization activity is more sensitive towards: nitrogen compounds. The results also show that the pgisoning effect of pyridine is analogohs to that of the "nitrogen compounds" of diesel fraction of shale oil.

    Highly active catalysts for the conversion of quadricyclane to norbornadiene, poly-λ-mercaptopropylsiloxane-palladium(Ⅱ) complex and poly-tetraphenylporphyrincobalt (Ⅱ) complex supported on silica have been prepared.The rate constants km for the reaction were 2.7 and 2.9s-1 (g atom Pd/1)-1 at 20℃. respectively. These new catalysts, like previously reported polymer-supported catalysts for this reaction, lose some of their activities upon repeated recycling. It was elucidated by the measuremnt of the electron binding energy that catalysts inactivation is mostly due to the coordination of the product NBD with palladium to form irreversible complex. The procedure which reactivates the catalyst has been suggested.
