AbstractHydrogenating catalysts were prepared by inserting Ru into the pores of mesoporous Al-MCM-41 materials by selective adsorption of [Ru(NH3)(6)](3+). Ru/support catalysts were obtained after reduction with H-2. The activities of these catalysts in hydrogenation reactions were compared to those of Ru/HY and Ru/SiO2. The catalytic properties in the absence of sulfur were tested in benzene hydrogenation, and the intrinsic activities of all the catalysts (either supported on mesoporous materials or on zeolites) were identical. It was concluded from this result that the dispersion of the Ru metallic phase was similar for all these catalysts. These samples were tested in the tetralin hydrogenation in pure H-2 and in the presence of H2S (330 ppm of H2S in H-2). They were found to be much less active than the zeolite-supported catalysts in the presence of H2S. It is proposed that the lower activity of the catalysts supported on mesoporous materials is either due to their milder acidity, as evidenced by NH3-TPD, cumene cracking and pyridine desorption experiments, or to the localization of the Ru nanoparticles on alumina islands.
