Conversion of renewable hydrocarbons to transportation fuels is required to reduce carbon emission, limit the use of fossil fuels, and develop renewable energy sources. Sorbitol, xylitol and trehelose are polyalcohols generated from the liquefaction of various sugars and carbohydrates in biomass from algae, corn, sugarcane, switchgrasses, and biological wastes. Mixtures of aqueous polyols and fuel feedstocks are catalyzed over metal catalysts to produce hexanes, pentanes, and lighter hydrocarbons. By managing the catalyst, reaction conditions and sulfur content, the octane value of the product fuel is dramatically increased.
