Patent No. 8,900,447

Description:
This patent implements a reaction to remove sulfur from gasoline at low temperature, at atmospheric pressure, and without the use of any oxidizing agents. These features allow for much cheaper removal of sulfur compounds from gasoline.

Abstract:
A method and a product made by treating a sulfur-containing hydrocarbon heavy feed, e.g., heavy crude asphaltene reduction is disclosed herein. The method comprises the steps of: mixing the sulfur-containing hydrocarbon heavy feed with a hydrogen donor solvent and an acidified silica to form a mixture and oxidizing the sulfur in the mixture at a temperature between 50° C. and 210° C., wherein the oxidation lowers the amount sulfur in the sulfur-containing hydrocarbon heavy feed by at least 90%.
