Abstract:
1. In a process for treating a pyrolysis oil derived from a material comprising lignocellulose in which a) a feed comprising the pyrolysis oil is subjected to a hydrodeoxygenation step in the presence of a catalyst comprising an active component on a catalyst carrier that is inert at 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 obtained in a) thereby producing a separated partially deoxygenated pyrolysis oil; the improvement comprising the further steps of c) providing to a hydrogenation step at least a portion of the separated partially deoxygenated pyrolysis oil having an oxygen content of from 10 to 30 wt %; d) hydrogenating, in the hydrogenation step, the separated partially deoxygenated pyrolysis oil from 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 obtained in d).
