Claim:
1. A process for the production of hydrocarbon products from a feed comprising at least one non-pre-treated bio-oil, wherein the process comprises: a first step for hydroreforming the feed in the presence of hydrogen and a hydroreforming catalyst comprising at least one transition metal selected from elements from groups 3 to 12 of the periodic classification of the elements and at least one support selected from activated carbon, silicon carbides, silicas, transition aluminas, silica-aluminas, zirconium oxide, cerium oxide, titanium oxide and transition metal aluminates, used alone or as a mixture, in order to obtain at least one liquid effluent comprising at least one aqueous phase and at least one organic phase; and a second step for hydrotreatment and/or hydrocracking of at least a portion of the organic phase obtained from the first step for hydroreforming in order to obtain a hydrocarbon effluent, in which at least a portion of the organic phase obtained from the first step for hydroreforming is recycled to said first step for hydroreforming as a mixture with said feed, with a recycle ratio equal to the ratio of the mass flow rate of said organic phase to the mass flow rate of the non-pre-treated bio-oil in the range 0.05 to 2 and in which the hydrocarbon effluent obtained from the second step for hydrotreatment and/or hydrocracking is not recycled to said first step for hydroreforming.
