Elaboration, caractérisation et études des propriétés catalytiques de matériaux carbonés poreux et fonctionnalisés par du molybdène

Abstract : Preparation and characterization of a new catalyst designed for hydrotreating petroleum feedstocks are described in the present work. Blocks maded of compressed expanded graphite are impregnated by polyfurfuryl alcohol, pyrolyzed and activated. These successive steps lead to monoliths whom structure corresponds to a thin active carbon layer deposited on a highly porous graphite backbone. Their elastical and conducting properties are described at each step of their preparation. Given their surface microporosity, these monoliths are quite good catalyst supports. Impregnation with MoCl5 (either in liquid or in vapor phase) followed by a subsequent carburization leads to a phase which is much better dispersed than in three other active carbons studied for comparison. The monoliths thus exhibit a high activity in HDN of indole and quite promising performances in HDS of dibenzothiophene.
