Hydrodesulfurization process for the production of low-sulfur hydrocarbon mixture
Low-sulfur content hydrocarbon mixtures and fuel oil blends below 0.2 or below 0.1 wt.% sulfur are obtained by hydrodesulfurizing vacuum gas oil under a hydrogen partial pressure of 300 to 800 psig with a select high activity desulfurization catalyst. Further embodiments include the hydrodesulfurization of sulfur-containing vacuum residuum and (1) mixing portions of the desulfurized hydrocarbon residuum with the vacuum gas oil feed or (2) blending fuel oil from portions of the desulfurized vacuum gas oil and desulfurized vacuum residuum product. Further process steps include (3) deasphalting of vacuum residuum or (4) hydrodesulfurizing vacuum residuum with delayed coking of at least a portion of the product. (auth)
