Abstract:
1. A process of hydrodesulfurizing a hydrocarbon mixture, which comprises: reacting said hydrocarbon mixture containing olefins and boiling within the range of C a) an acidic carrier consisting of a silica and alumina gel, amorphous to X-rays, with a molar ratio SiO b) a mixture of molybdenum and cobalt deposited on the carrier in an overall quantity ranging from 2 to 67% by weight with respect to the total amount of components (a)+(b), thereby effecting said hydrodesulfurization with concomitant skeletal isomerization of the olefins of said mixture under the hydrogenation conditions of the process which results in a ratio HYD/ISO ranging from 0.7 to 2.5, wherein HYD is the ratio of non-isomerized olefins, that have been hydrogenated, to olefins in the hydrocarbon mixture and ISO is the ratio of isomerized, hydrogenated and non-hydrogenated olefins to the sum of isomerized, hydrogenated and non-hydrogenated, olefins and non-isomerized, hydrogenated and non-hydrogenated, olefins.
