NOVELTY - Treating pyrolysis oil derived from a material comprising lignocellulose comprises: (a) subjecting a feed comprising pyrolysis oil to hydrodeoxygenation in presence of catalyst; (b) separating partially deoxygenated pyrolysis oil from product stream obtained in step (a); (c) providing at least a portion of separated partially deoxygenated pyrolysis oil having an oxygen content of 10-30 wt.%; (d) hydrogenating separated partially deoxygenated pyrolysis oil obtained from step (c); and (e) separating at least one product fraction from hydrogenated product stream obtained in step (d).    USE - The method is useful for: treating pyrolysis oil derived from a material comprising lignocellulose; and producing hydrocarbon products from biomass (claimed), where the hydrocarbon products include aromatic compounds, paraffins and cyclic hydrocarbon compounds.    ADVANTAGE - The process: reduces the coke formation in the reactor as the hydrogenation step is carried out in the presence of a hydrocarbon feed derived from a mineral crude oil; enables the use of decentralized pyrolysis plants which may be located near the source of biomass feedstock, thus reducing the transportation costs by transporting pyrolysis oil instead of the biomass; the pyrolysis oil comprises only a small amount of minerals, thus reducing the inorganic content that could poison the catalysts including the hydrodeoxygenation and hydrotreating catalysts; reduces the amount of hydrogen consumed during the hydrodeoxygenation and hydrotreatment steps as the pyrolysis comprises less amount of oxygen; and is economically favorable as the hydrodeoxygenation step takes place in a close proximity of the refinery.    DETAILED DESCRIPTION - Treating pyrolysis oil derived from a material comprising lignocellulose comprises: (a) subjecting a feed comprising the pyrolysis oil to hydrodeoxygenation in the presence of a catalyst comprising an active component on a catalyst carrier that is inert during the reaction conditions, to obtain a product stream comprising a partially deoxygenated pyrolysis oil; (b) separating the partially deoxygenated pyrolysis oil from the product stream to produce a separated partially deoxygenated pyrolysis oil; (c) providing at least a portion of the separated partially deoxygenated pyrolysis oil having an oxygen content of 10-30 wt.%; (d) hydrogenating the separated partially deoxygenated pyrolysis oil obtained from step (c) in the presence of a catalyst and a hydrocarbon feed derived from a mineral crude oil, to obtain a hydrogenated product stream; and (e) separating at least one product fraction from the hydrogenated product stream. An INDEPENDENT CLAIM is also included for producing hydrocarbon products from biomass comprising: (f) pyrolyzing a biomass comprising lignocellulose to obtain pyrolysis oil; (g) subjecting the pyrolysis oil to hydrodeoxygenation in the presence of a catalyst comprising an active component on a catalyst carrier that is inert during the reaction conditions, to obtain a product stream comprising a partially deoxygenated pyrolysis oil; steps (b)-(e) as above per se; and (h) blending at least one product fraction obtained with at least another fuel compound and/or an additive to produce a biofuel.
