HDS OF A MODEL FCC GASOLINE OVER TRANSITION MONOMETALLIC SULPHIDE (TMS)CATALYSTS

摘要

Transition monometallic sulphide (TMS)catalysts are known to be active in the various hydrotreating reactions [1].Recently,it has been established that volcano type relationships between the ab initio calculated metal-sulphur bond energies E(M-S)and the activity in the hydrodesulfurization of dibenzothiophene (HDS)on the one hand,and the hydrogenation of biphenyl and toluene (HYD)on the other,were obtained [2-8].Indeed it could be possible to rationalize and to predict the performances of sulphide catalysts from the principle of Sabatier.However,no data was reported in the literature concerning the hydrogenation of alkenes.
