Abstract: The present invention is related to a catalytic process, which includes catalytic compositions for depolymerisation and deoxygenation of lignin contained in the biomass for obtaining aromatic hydrocarbons. The catalytic composition consists of at least one non-noble element from group VIIIB of the periodic table supported on a mesoporous matrix composed of an inorganic oxide, which can be alumina surface-modified with a second inorganic oxide with the object of inhibiting the interaction between the active component and the support. The process of lignin depolymerisation consists of dissolving lignin in a mixture of protic liquids, reacting it I a reaction system by batch or in continuous flow at inert and/or reducing atmosphere, at a temperature of between 60 to 320° C. and a pressure of from 5 to 90 kg/cm2.

Abstract: The present invention relates to a catalytic formulation used in the hydroprocessing of light and middle oil fractions, preferably in hydrodesulfurization and hydrodenitrogenation reactions to obtain diesel with ultra low sulfur content less than or equal to 15 ppm in weight. The catalytic formulation, object of the present invention, consists of at least one metal of Group VI B and at least one metal of Group VIII B and one element of Group V A of the periodic table deposited on a support based on surface modified alumina with an inorganic oxide of a metal of Group II A, IV A and/or IV B. And containing an impregnated organic compound containing at least one hydroxyl group and at least one carboxyl group and that can contain or not at least one sulfide group in its structure. The catalytic formulation, object of the present invention, allows processing of the oil fractions with initial and final boiling temperatures between 150 and 450° C.

Abstract: The invention relates to a method of preparing a catalytic composition comprising at least one non-noble metal from group VIII and at least one metal from group VIB of the periodic table. The invention also relates to the catalytic composition thus produced, which has a high specific activity in reactions involving the hydroprocessing of light and intermediate fractions, preferably in reactions involving the hydrotreatment of hydrocarbon streams, including hydrodesulphurisation (HDS), hydrodenitrogenation (HDN) and hydro-dearomatisation (HDA).
