Abstract:
1. A process for the removal of sulfur from a hydrocarbon fuel, the process comprising the steps of: supplying the hydrocarbon fuel to a hydrotreating unit, the hydrotreating unit comprising a catalyst bed and a hydrogen gas source, said catalyst bed comprising a desulfurization catalyst, wherein contacting the hydrocarbon fuel with the desulfurization catalyst produces a partially desulfurized hydrocarbon fuel stream; removing gaseous products from the partially desulfurized hydrocarbon fuel stream to produce a gas-free partially desulfurized hydrocarbon fuel stream; then supplying the gas-free partially desulfurized hydrocarbon fuel stream after removing the gaseous products to an adsorption unit, said adsorption unit comprising an adsorbent composition for the removal of sulfur, the adsorbent composition comprising a composite alumina material comprising between about 5 and 50% by weight of carbon and sulfur, wherein the composite alumina material is prepared by heating the composite material to a temperature of between about 200° C. to 800° C. in an oxygen containing atmosphere, wherein the composite alumina material is partially calcined such that a portion of the carbon component is not burned out; and contacting the adsorbent composition and the gas-free partially desulfurized hydrocarbon fuel stream to substantially remove sulfur therefrom to produce a desulfurized hydrocarbon fuel stream.
