Abstract: Selective and deep desulfurization of a high sulfur content mogas naphtha, with reduced product mercaptans and olefin loss, is achieved by a two stage, vapor phase hydrodesulfurization process with interstage separation of at least 80 vol. % of the H2S formed in the first stage from the first stage, partially desulfurized naphtha vapor effluent fed into the second stage. At least 70 wt. % of the sulfur is removed in the first stage and at least 80 wt. % of the remaining sulfur is removed in the second stage, to achieve a total at least 95 wt. % feed desulfurization, with no more than a 60 vol. % feed olefin loss. The second stage temperature and space velocity are preferably greater than in the first. The hydrodesulfurization catalyst preferably contains a low metal loading of Co and Mo metal catalytic components on an alumina support.

Abstract: Disclosed is a process wherein a two-stage hydroconversion process for converting a heavy hydrocarbonaceous feedstock to lower boiling products which process comprises: (a) reacting the feedstock in a first reaction stage at hydroconversion conditions which include temperature from about 650.degree. F. to 900.degree. F., and hydrogen partial pressure ranging from about 50 to 5000 psig in the presence of a metal compound which is convertible to a solid, non-colloidal, metal-containing catalyst, said metal selected from the group consisting of metals from Groups IVB, VB, VIB, VIIB, and VIII, of the Periodic Table of the Elements, wherein said metal compound is: (i) soluble in the hydrocarbonaceous feed; or (ii) soluble in an organic medium that can be dispersed in the hydrocarbonaceous oil, or (iii) soluble in water resulting in an aqueous solution which can then be dispersed in the hydrocarbonaceous feedstock; (b) passing the resulting product stream to a second reaction stage where it is reacted under slurry hydrotreating conditions which include: (i) temperature in the range of 650.degree. F. to 750.degree. F., with the promise that this slurry hydrotreating stage be operated at a temperature at least 25.degree.
