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%.
