Реферат: The main kinetic features of thiophene hydrogenolysis on mono- and bimetallic sulphide catalysts were analyzed. Sulphide molybdenum and tungsten catalysts were shown to differ from nickel catalysts in that they exhibited higher hydrogenation activity. According to the data from the temperature-programmed reduction (TPR) the amount of sulphur removed at TPR was not functionally dependent on the activity of bimetallic sulphide catalysts in thiophene hydrogenolysis. A new reaction mechanism of thiophene hydrogenolysis is proposed with consideration given to the structure of the active component of bimetallic catalysts. The adsorption and activation of a thiophene molecule is supposed to occur on nickel atoms stabilized on the side planes of MoS2 (WS2) single slabs, while hydrogen activation is achieved on the Mo(W) atoms. A high rate of chemical reaction seems to be achieved by synchronous interaction of thiophene and hydrogen molecules in the coordination sphere of a bimetallic sulphide species in the rate-determining reaction step.
