Abstract:
A process for desulfurization of a hydrocarbon liquid comprisinga) contacting sulfur-laden hydrocarbon liquid with a packed bed catalyst composition composed of sponge nickel metal alloy to produce a hydrocarbon liquid having a reduced sulfur content; b) separating from the packed bed catalyst composition and recovering the hydrocarbon liquid having a reduced sulfur content; c) regenerating the packed bed catalyst composition by treating it with an aqueous solution of at least one oxidant selected from the group consisting of hydrogen peroxide, an alkali metal hypochorite, an alkali metal nitrate, an organic peroxy acid or mixtures thereof, to remove sulfur contained therein; d) contacting the regenerated packed bed catalyst composition of step c), alone or with additional packed bed catalyst composition, with additional sulfur-laden hydrocarbon liquid to remove sulfur therefrom; and e) cyclically repeating steps b), c) and d).
