Abstract

Alumina-silica (Al2O3-SiO2) composite supports were examined to find the optimum state of support (i.e., composition and morphology). SiO2 content in the Al2O3-SiO2 support induced a shift of the main peak to higher frequency ascribed to an increased amount of Mo8O264-. A 75 wt% Al2O3-25 wt% SiO2 support had homogeneously dispersed alumina particles of smaller size with high crystallinity. Hydrodesulfurization (HDS) of straight-run gas oil and its conventionally hydrotreated straight-run gas oil was performed over NiMo sulfides supported on Al2O3-SiO2 composites. The high crystallinity of NMASA2-27 may be related to the high HDS and hydrogenation activity of NiMo sulfides due to its moderate interaction with the alumina surface.
