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.

What is claimed: 1. 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
What is claimed: 1. 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. 2. The process of claim 1, further comprising the step of drying the partially calcined composite material before contacting the middle distillate petroleum hydrocarbon fuel with the composite material in the reactor. 3. The process of claim 1, wherein the carbon component is a non-activated carbon. 4. The process of claim 1, wherein the composite material is partially calcined at a temperature in the range from 250° C. to 600° C. 5. The process of claim 1, wherein the surface area of the partially calcined composite material is preferably from 100-250 m2/g. 6. The process of claim 1, wherein the step of partially calcining the composite material comprises the steps of heating the composite material to a temperature in the range of 200° C. to 800° C. in an oxygen containing atmosphere, maintaining the composite material at the designated temperature, and cooling the composite material to room temperature. 7. The process of claim 1, further comprising the step of regenerating the partially calcined composite material by washing the composite material with a hydrocarbon solvent and drying the composite material at a temperature less than 100° C. 8. The process of claim 1, wherein the carbon and sulfur components comprise between about 5 and 50% by weight of the composition. 9. The process of claim 1, wherein the carbon and sulfur components comprise greater than about 50% by weight of the composition. 10. The process of claim 1, wherein the sulfur component is selected from the group consisting of a metal sulfide and a sulfur oxide. 11. The process of claim 10, wherein the metal of the metal sulfide is selected from the group consisting of chromium, molybdenum, tungsten, uranium, selenium, tellurium, polonium, iron, cobalt, nickel, zinc, copper, ruthenium, phosphorus, rhodium, palladium, osmium, iridium and platinum. 12. The process of claim 10, wherein the metal of the metal sulfide is selected from the group consisting of molybdenum, and cobalt. 13. The process of claim 1, wherein the carbon and sulfur are present in an amount of at least 26.6% by weight.
