In this paper, carbon nano- particles as hard template , in an atmosphere of water vapor synthesis of mesoporous ZSM-5 zeolite , the use of the synthesized mesoporous ZSM-5 zeolite and alumina composites prepared by mechanical mixing carrier, supported metal component prepared NiMo / composite supported catalyst and its HDS and HDN activity were evaluated. Paper systematically investigated the synthesis process of zeolite particles and nano- carbon ratio of ethanol added , crystallization time , calcination temperature on mesoporous ZSM-5 zeolite structure and properties of , and draw the appropriate synthesis conditions . Using XRD, BET, Py-IR, SEM, TEM, EDAX, AAS by means of the synthesized mesoporous characterization. The results show that , by choosing different size soot particles and soot particles added to the proportion of change , can regulate mesoporous ZSM-5 zeolite pore size distribution , pore volume, pore size and wall thickness ; pore volume mesoporous molecular sieve having a smaller high crystallinity , strong acidity and good thermal stability and hydrothermal stability . Papers using XRD, BET, Py-IR, NH 3 -TPD, HRTEM and other means of support and catalyst characterization. Characterization results showed that the alumina as the carrier of catalyst, the introduction of mesoporous ZSM-5 zeolite catalyst of the mesopore volume and pore diameter has increased , B increase in acid sites on the catalyst surface layer MoS 2 < / sub> reduced the number of chips , MoS 2 , the average chip stack layers increases . Respectively, DBT and quinoline as a model compound , using high pressure microreactor hydrodesulfurization catalyst and HDN activity evaluation carried out . Alumina as the carrier catalyst, mesoporous molecular sieves - aluminum oxide compound in the supported catalyst having a strong acidity , and promote the CS, CN bond rupture , hydrogenolysis catalyst is improved desulfurization and denitrification capacity . Meanwhile , mesoporous molecular sieves join, weakened carrier and the interaction between the active component , the MoS 2 chip stacking layers increases , the number of active sites increased hydrogenation catalyst hydrogenation activity enhanced . With microporous zeolite - alumina composite carrier catalyst, mesoporous molecular sieves - alumina composite carrier catalyst pores advantage, large pore volume and pore diffusion resistance reduces the macromolecules to avoid side reactions .
