NOVELTY - Integrated biofuel production process comprises: (a) converting a biomass to yield at least one alcohol and residual biomass; (b) gasifying the residual biomass to produce carbon monoxide and/or hydrogen, thus producing thermal energy; (c) synthesizing a liquid hydrocarbon fuel from the alcohols through a dehydration and an oligomerization reaction using at least a portion of the thermal energy produced by gasifying the residual biomass; and (d) converting the residual biomass into energy and/or at least one commercially viable co-products e.g. acids and ketones.    USE - The processes are useful for producing integrated biofuel, hydrocarbon fuel and chemicals, where the chemicals are paraffins, olefins, aromatics, naphthas, ethylene, acetylene, benzene, cyclohexene, xylene, toluene or ethylbenzene (all claimed), and the fuels are useful for powering internal combustion engines (e.g. gasoline and jet engines), diesel fuel, and industrial boilers.    ADVANTAGE - The process: is simple, direct, and provides for the shortest or minimum path between biomass and transportation fuels with alcohols as intermediates, while avoiding hydrogen use during processing; and allows the manufacture of drop-in substitutable fuels to be used as it is, without modifications instead of conventional petroleum based fuels. In the process, the heat and mass generated increases the overall process efficiency and lowers financial costs for processing and capital equipment, manages environmental impact, and enables a relatively high degree of yield by an enhanced usage of fresh water and thermal energy in comparison to the amount of biomass processed.    DETAILED DESCRIPTION - Integrated biofuel production process comprises: (a) converting a biomass to yield at least one alcohol and residual biomass; (b) gasifying the residual biomass to produce carbon monoxide and/or hydrogen, thus producing thermal energy; (c) synthesizing a liquid hydrocarbon fuel from the alcohols through a dehydration and an oligomerization reaction using at least a portion of the thermal energy produced by gasifying the residual biomass; and (d) converting the residual biomass into energy and/or at least one commercially viable co-products, where the co-products are acids, ketones, alcohols, ethers, alkylbenzenes, fuel additives, biopolymers, proteins for animal and human consumption, or surfactants. INDEPENDENT CLAIMS are also included for:    (1) a hydrocarbon fuel produced by the process;    (2) a biofuel produced by the process;    (3) a chemical production process comprising: converting biomass to at least one alcohol and a residual biomass; gasifying the residual biomass to produce at least one hydrocarbon gasses, carbon monoxide, and/or hydrogen; and synthesizing at least one chemical from the alcohols, and the hydrocarbon gases, carbon monoxide and/or hydrogen;    (4) a process (I) for making at least one hydrocarbon fuel from at least one alcohol comprising: dehydrating the alcohols to yield at least one olefins; and oligomerizing the olefins in an oligomerization reactor to yield at least one commercially viable products comprising chemicals, transportation fuels, linear and branched higher olefins, feedstock, detergents, petrochemicals, oil additives or high-octane gasoline; and    (5) a hydrocarbon fuel produced by the process (I).
