NOVELTY - Producing a renewable gasoline from cellulosic biomass involving: a) feeding a cellulosic feedstream; b) using an ionic separator (ISEP) to generate a sugar/polyol stream (i) and a water/carboxylate stream (ii): i) generating hydrocarbons from sugars and polyols using using an isomerization (ISOM) reactor; ii) generating alcohol from the carboxylate stream using hydrodeoxygenation (HDO) reactor, separating alcohol, water, and hydrogen using a cold separator, and removing water using a membrane separator; and c) producing product stream comprising alcohol and gasoline range hydrocarbons.    USE - As system for producing a renewable gasoline from cellulosic biomass (claimed).    ADVANTAGE - The method enables to manufacture advanced cellulosic gasoline; decreases acidity by removing the organic acids and upgrades pyrolysis oil into useful products in a cost effective manner.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following:    (1) system for producing a renewable gasoline from cellulosic biomass comprising: a) a cellulosic feedstream; b) an ionic separator (ISEP) generating a sugar/polyol stream (i) and a water/carboxylate stream (ii): i) a polyol stream system comprising: (1) a hydrotreating (HT) reactor to generate hydrocarbons from sugars and polyols, (2) an isomerization (ISOM) reactor to generate isomerized gasoline range hydrocarbons; ii) a carboxylate stream system comprising: (1) a hydrodeoxygenation (HDO) reactor generating gasoline from the carboxylate stream, hydrogen, and a portion of the hydrocarbon stream (i), (2) a cold separator to separate alcohols, water, and hydrogen, and (3) a membrane separator to remove water from alcohol; and c) a mixer for at least one product stream comprising alcohol and gasoline range hydrocarbon products;    (2) renewable gasoline produced from cellulosic biomass by method involving: a) feeding a cellulosic feedstream; b) using a separator (ISEP) to generate a polyol stream (i) and a water/carboxylate stream(ii): i) generating hydrocarbons from polyols using a hydrodesulfurization (HDS) reactor and converting the hydrocarbons to isomerized gasoline range hydrocarbons using an isomerization (ISOM) reactor. ii) generating alcohol from the carboxylate stream (b), hydrocarbons (i) and recycled hydrogen in a hydrodeoxygenation (HDO) reactor, separating alcohol, water, and hydrogen using a cold separator, and removing water using a membrane separator; and c) producing a renewable gasoline by blending alcohol and gasoline range hydrocarbons.
