Hydrodesulfurization of Atmospheric Gas Oil over NiMo/Aluminum Borate Catalysts in a Trickle Bed Reactor

摘要

A precipitation technique at constant pH value was used to prepare a series of aluminum borates (ABs) with various Al/B atomic ratios. These samples have been characterized with respect to surface areas, pore volumes, and pore size distributions. These materials were used as the supports of Ni-Mo catalysts. Hydrotreating reactions of atmospheric gas oil (AGO) were carried out over these sulfided catalysts in a bench-scale trickle bed reactor.
