Abstract
A process for hydrodesulfurization of a sulfur-containing petroleum hydrocarbon diesel gas oil comprising; hydrodesulfurizing a sulfur-containing petroleum hydrocarbon diesel gas oil feedstock, separating the hydrodesulfurized diesel gas oil feedstock into light and heavy fractions by distillation, hydrodesulfurizing further the separated heavy fraction, and mixing the further hydrodesulfurized heavy fraction and the separated light fraction into the hydrocarbon diesel gas oil.
