NOVELTY - Producing hydrocarbon products from a feedstock comprising at least one bio oil, comprises introducing feedstock in hydroreforming in presence of hydrogen in at least one three-phase reactor containing first supported hydroreforming catalyst comprising e.g. transition metal of groups 3-12 and support e.g. active carbon and second catalyst, operated in ebullated bed to produce at least one liquid effluent of at least one aqueous phase and at least one organic phase; and recycling at least a portion of organic phase from effluent in mixture with the feedstock comprising at least one bio oil.    USE - The process is useful for producing hydrocarbon products comprising chemicals and/or hydrocarbon products to be incorporated into pool of liquid fuels comprising biofuels, from feedstock comprising at least one bio oil from biomass comprising plants, herbs, trees, wood chips, seeds, fibers, seed husks, aquatic plants, hay and other sources of lignocellulosic materials, comprising from municipal waste, food processing waste, forest waste, logging residues, agricultural and industrial wastes (e.g. sugar cane bagasse, the waste from oil palm cultivation, sawdust or straw) or from pulp by-products and optionally recycled paper, or by products from paper mills.    ADVANTAGE - The process: utilizes the catalyst, which is uniformly dispersed in the reactor, provides increased catalytic effect and avoids the polymerization reactions; provides greater flexibility to the feedstock comprising at least one bio oil, recovered from pyrolysis of biomass, which has wide viscosity ranges of water content and degree of polymerization depending on the origin of the biomass and the pyrolysis process implementation; avoids thermal reactions outside the reaction zone containing the supported catalyst, thus allows for better operation of the unit, preferably in separation zone; and facilitates the conversion reactions and deoxygenation of bio oil on catalyst to improve the dissolution of hydrogen gas in recycled organic phase obtained from first stage of hydroreforming and reduces the recycling of all or part of organic phase from the hydroreforming, thus reduces the investment and operating costs.    DETAILED DESCRIPTION - Producing hydrocarbon products from a feedstock comprising at least one bio oil, comprises introducing the feedstock in a first stage of hydroreforming in the presence of hydrogen to produce at least one liquid effluent comprising at least one aqueous phase and at least one organic phase; and recycling at least a portion of organic phase from the effluent in mixture with the feedstock comprising at least one bio oil. The first step of hydroreforming is carried out at 200-380 degrees C at a pressure of 3-30 MPa, at an hourly space velocity of 0.1-5 hour-1, in at least one three-phase reactor operated in an ebullated bed, upflow of liquid and gas, or the reactors each containing at least a first supported hydroreforming catalyst and at least one second catalyst dispersed in reactor, the second catalyst is circulating from bottom to top with the load in reactors and is regenerated with the liquid effluent product from the reactors. The ratio of recycling is equal to the ratio of the mass flow of the organic phase to the mass flow rate of the non-pretreated bio-oil of 0.05-5. The first supported hydroreforming catalyst has a size of 0.1-5 mm and comprising at least one transition metal comprising elements of groups 3 to 12 and at least one support comprising active carbon, silicon carbide, silicas, transition aluminas, silica-aluminas, zirconium oxide, cerium oxide, titanium oxide and/or transition metal aluminates. The second catalyst has size of 0.001-100 mu m, which is optionally supported.
