Abstract:
1. A process for producing hydrocarbon products from whole pyrolysis oil feedstock comprising: (a) partially deoxygenating the whole pyrolysis oil feedstock in a partial deoxygenation zone by contacting the pyrolysis oil with a partial deoxygenation and hydrogenation catalyst in the presence of hydrogen at deoxygenation conditions to produce a partially deoxygenated pyrolysis oil stream comprising water, gasses, light ends, and hydrocarbons; (b) passing the partially deoxygenated pyrolysis oil stream to a separation zone to separate a water, gasses, and light ends stream from a remainder stream wherein the light ends of the water, gasses, and light ends stream are processed other than blending with the product stream of step (c); and (c) passing the remainder stream to a full deoxygenation zone and deoxygenating the remainder stream by contacting with a deoxygenation catalyst under deoxygenation conditions, to generate a product stream comprising hydrocarbon compounds useful as a fuel or a fuel blending component in the boiling point ranges of gasoline, aviation, diesel, and any combination thereof wherein the product stream comprises from about 1 to about 14 wt % hydrocarbon compounds having a boiling point of about 400° C. to about 600° C.
