Abstract
The invention relates to a method for producing a petrochemical product from biomass, involving the following steps: dewatering and drying biomass; producing crude oil by the direct liquefaction of the dried biomass; hydrogenating the crude oil into hydrocarbons; and refining the hydrocarbons into a petrochemical product. Said method is characterized in that the hydrogen used for hydrogenating the crude oil is obtained from the wastewater accumulated during the dewatering and drying of the biomass and/or during the direct liquefaction and from the residue accumulated during the direct liquefaction.
