Abstract
Desulfurization process of a hydrocarbon oil, practically free of ethylenically or acetylenically unsaturated compounds, characterized in that it comprises three stages, of which the first one comprises treating the hydrocarbon oil with sulfuric acid, under the conditions indicated above, and/or the vaporize it and then pass the steam thus obtained on a contact material containing zinc oxide, manganese oxide or iron oxide, at a temperature comprised between 350º C, and 450º C, and at a pressure comprised between 1 and 50 atmospheres, by which medium is removed at least 70% of the sulfur contained in the hydrocarbon oil; the second stage comprises passing the vaporized hydrocarbon, together with hydrogen, at a temperature comprised between 350º C and 450º C and at a pressure comprised between 1 and 50 atmospheres, on a hydro-desulphurisation catalyst, and the third stage comprises contacting the product of the second stage, with an absorption material of hydrogen sulfide.
