NOVELTY - A system consists of cellulosic feedstream, ionic separator (ISEP) generating sugar/polyol stream and water/carboxylate stream, and mixer for product stream(s) containing alcohol and gasoline range hydrocarbon products. The polyol stream system has a hydrotreating (HT) reactor, and an isomerization (ISOM) reactor. The carboxylate stream system has a hydrodeoxygenation (HDO) reactor, hydrogen, and portion of hydrocarbon stream, a cold separator to separate alcohols, water, and hydrogen, and membrane separator to remove water from alcohol.    USE - System for producing renewable gasoline (claimed), hydrocarbon fuels, products used as hydrocarbon building blocks, and bio-oil used in transportation fuel applications.    ADVANTAGE - The system has reduced baseline greenhouse gas emissions, and makes additive non-added gasoline by directly blending the alcohol product into a neat hydrocarbon fuel basestock.    DETAILED DESCRIPTION - A system consists of cellulosic feedstream, ionic separator (ISEP) generating sugar/polyol stream and water/carboxylate stream, and mixer for product stream(s) containing alcohol and gasoline range hydrocarbon products. The polyol stream system has a hydrotreating (HT) reactor to generate hydrocarbons from sugars and polyols, and an isomerization (ISOM) reactor to generate isomerized gasoline range hydrocarbons. The carboxylate stream system has a hydrodeoxygenation (HDO) reactor generating gasoline from carboxylate stream, hydrogen, and portion of hydrocarbon stream, a cold separator to separate alcohols, water, and hydrogen, and membrane separator to remove water from alcohol. INDEPENDENT CLAIMS are included for the following:    (1) renewable gasoline which is premium fuel with up to 10% alcohol (E10), 20% alcohol (E20), 85% alcohol (E85), or other blended gasoline product; and    (2) production of renewable gasoline from cellulosic biomass, which involves feeding a cellulosic feedstream, generating a sugar/polyol stream and a water/carboxylate stream using an ISEP, generating hydrocarbons from sugars and polyols using a HT reactor and converting the hydrocarbons to isomerized gasoline range hydrocarbons using an ISOM reactor, generating alcohol from the carboxylate stream, hydrocarbons and recycled hydrogen in HDO reactor, separating alcohol, water, and hydrogen using a cold separator, and removing water using a membrane separator, and producing product stream(s) comprising alcohol and gasoline range hydrocarbons.    DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a pervaporation membrane including 500 ml reservoir with thermostat, feed stream, return regulation valve, concentrate, permeate and a vacuum pump.
