Study on modification of NoO_3 For Ni/sepiolite hydrogenation catalysts

摘要

A series of catalysts containing nickel are prepared by impregnation and the influence of NoO_3 on Ni/sepiolite catalysts is investigated by benzene hydrogenation reaction and CS_2 poisoning. The results reveal that the addition of molybdenum increases the activity of hydrogenation and the number of active sites and reduces the activation enthalpy △H≠ and activation entropy △S≠ of the intermediate formed by catalyst and reactant.
