Claim:
1. A method for removing a portion of sulfur contained in a hydrocarbon, comprising contacting said sulfur containing hydrocarbon in gaseous form to a catalytic composition comprising copper oxide in an amount ranging from 20 weight percent (wt %) to 45 wt %, zinc oxide in an amount ranging from 12 wt % to less than 20 wt %, CeO 2 in the form of particles ranging in diameter from 5 nm to 10 nm, in an amount ranging from 0.1 wt % to 10 wt % and aluminum oxide in an amount ranging from 20 wt % to 40 wt %, wherein said catalytic composition has an X-ray amorphous oxide phase, and a formula Cu x Zn 1-x Al 2 O 4 wherein x ranges from 0 to 1, highly dispersed crystalline ZnO and CuO, said contacting occurring in the presence of pure oxygen at a gas hourly space velocity (GHSV) of from 1,000 to 20,000 h −1 , said catalytic composition prepared by: (i) combining an aqueous solution containing each of copper nitrate, zinc nitrate, and aluminum nitrate with an alkaline solution containing NaOH and/or at least one of (NH (ii) aging said precipitate; (iii) filtering and washing said precipitate; (iv) drying said precipitate for at least 10 hours, at a temperature of at least 100° C.; and (v) combining the precipitate with a binder selected from the group consisting of poly-ethylene oxide, polyvinyl alcohol, a sol of aluminum pseudoboehmite, silica gel and mixtures thereof, said binder being added in amount ranging from 1 to 10 weight % of said precipitate, to from an extrudable mixture, extruding said mixture through a die to form an extrudate drying said extrudate for 24 hours at room temperature, followed by drying said extrudate at 100° C. for from 2-4 hours, and raising temperature to 500° C., at a rate of from 2-5° C./minute, to calcine said extrudate for from 2-4 hours.
