Integrated biofuel processing system

A chemical production process comprising the steps of:

• (a) converting a biomass to one or more alcohols and a residual biomass;
• (b) gasifying the residual biomass to produce one or more hydrocarbon gasses, carbon monoxide, hydrogen or mixtures thereof;
• (c) synthesizing one or more chemicals from the alcohols and the hydrocarbon gases, carbon monoxide, hydrogen, or mixtures thereof;
• and
• (d) combusting the hydrocarbon gasses, the carbon monoxide, the hydrogen, or mixtures thereof to produce heat and electricity, wherein the heat and electricity are recycled back into the process to perform step (c).

A process for making one or more hydrocarbon fuels from one or more alcohols comprising the steps of:

• (a) dehydrating the one or more alcohols to yield one or more olefins;
• and
• (b) oligomerizing the one or more olefins in an oligomerization reactor to yield one or more commercially viable products selected from the group consisting of chemicals, transportation fuels, linear and branched higher olefins, feedstock, detergents, petrochemicals, oil additives, and high-octane gasoline;
• and
• (c) combusting a carbon monoxide, a hydrogen, or mixtures thereof from a biomass to produce heat and electricity, wherein the heat and electricity are recycled back into the process to perform step (c).

An integrated biofuel production process comprising the steps of:

• (a) pretreating a biomass;
• (b) hydrolyzing the converted biomass, wherein the pretreatment and hydrolysis processes are done by using a hot wastewater;
• (c) converting a biomass to yield one or more alcohols and a residual biomass;
• (d) gasifying the residual biomass to produce carbon monoxide, hydrogen or mixtures thereof, thereby producing thermal energy, wherein at least a portion of the thermal energy produced by the gasification of the residual biomass is recycled back into the process to perform step (c);
• (e) synthesizing a liquid hydrocarbon fuel from the alcohols using at least a portion of the thermal energy produced by gasifying the residual biomass;
• (f) converting the residual biomass into one or more commercially viable co-products, wherein the co-products are selected from the group consisting of acids, ketones, alcohols, ethers, alkylbenzenes, fuel additives, biopolymers, proteins for animal and human consumption, and surfactants;
• and
• (g) further comprising the step of combusting the carbon monoxide, the hydrogen, or mixtures thereof to produce heat and electricity, wherein the heat and electricity are recycled back into the process to perform step (c).
