Patent ID: 7578927

Claim:
A process for producing hydrocarbon products comprising: adding water to a mixture of pyrolysis oil and lignin; separating pyrolysis oil and lignin from the mixture comprising pyrolysis oil and lignin thereby generating a water rich phase stream and a pyrolytic lignin stream; passing the pyrolytic lignin stream to a hydrotreating unit thereby generating a deoxygenated light oil stream, wherein the hydrotreating unit is operated at a pressure in the range from about 5.5 MPa (800 psia) to about 8.3 MPa (1200 psia); passing the deoxygenated light oil stream to a separation unit thereby generating an aqueous stream and an organic stream; passing the organic stream to a hydrocracking unit and reacting the organic stream under mild hydrocracking conditions, thereby generating a product stream comprising hydrocarbon compounds useful for gasoline production or diesel fuel; and passing the water rich phase stream to a reforming unit, thereby generating a hydrogen stream.
