ABSTRACT:
A sulfur-containing naphtha is separated into at least three fractions. Each fraction is desulfurized separately by a different desulfurization method. Subsequently, the desulfurized fractions are recombined. The intermediate boiling point naphtha fraction is desulfurized by an alkali metal desulfurization process, preferably in the presence of added hydrogen.
