Abstract
A composition and process for removing sulfur from middle distillate petroleum hydrocarbon fuels. The composition includes an alumina component and a carbon component. The composition is present in an amount effective to adsorb sulfur compounds from the fuel. The alumina component and the carbon component preferably collectively comprise a composite material. The composition can further include a sulfur component, preferably a metal sulfide or sulfur oxide. The composition can also further include at least one compound having a Group VI or Group VIII metal from the periodic table.
Claims13
A process for removing sulfur from a middle distillate petroleum hydrocarbon fuel, the process comprising the steps of:
- partially calcining a composite material comprising an alumina component, a sulfur component, and a carbon component to produce a partially calcined composite material, such that a portion of the carbon component is not burned out;
- and
- contacting the middle distillate petroleum hydrocarbon fuel with the partially calcined composite material in an adsorptive reactor, the partially calcined composite material being present in the reactor in an amount operable to adsorb sulfur compounds from the middle distillate petroleum hydrocarbon fuel.
