Abstract: The invention relates to a process to manufacture advanced cellulosic gasolines. Dilute organic acids derived from pyrolized biomass are converted to their corresponding alcohols in a stand-alone hydrodeoxygenation unit followed by membrane pervaporation step to remove water. The alcohol product is blended directly into a neat hydrocarbon fuel basestock to make unadditized gasoline.
