Abstract
A process for the desulfurization of a sulfur-containing composition is described. The process comprises providing a sulfur-containing composition, adding an aqueous medium and a sulfur absorbent to the composition, and subjecting the resultant mixture to hydrothermal reaction under specific conditions to obtain a desulfurized product. When the sulfur-containing composition is made of vulcanized rubbers, the rubber can be converted into oily substances by treating the rubber product under supercritical conditions using an aqueous medium. The conversion reaction is facilitated by addition of metal oxides or salts.
