    摘要： Alcohols useful as fuel compositions are produced from biomass by pretreating the biomass prior to hydrolysis and fermentation. In the pretreatment, the biomass is contacted with an aqueous solution containing a dilute acid with concentration of up to 10 wt % producing a predigested stream containing an aqueous liquor that contains at least a portion of hemicelluloses and a residual biomass that contains celluloses and lignin; separating at least a portion of the aqueous liquor from the residual biomass providing an aqueous liquor stream and a pre-digested biomass stream; then contacting the pre-digested biomass stream with a cooking liquor containing at least one alkali selected from the group consisting of sodium hydroxide, sodium carbonate, sodium sulfide, potassium hydroxide, potassium carbonate, ammonium hydroxide, and mixtures thereof and water. A process that allows for higher recovery of carbohydrates and thereby increased yields is provided.

    摘要： A process converts a gas input stream comprising CO, CO2, and H2 by contact with fermentation liquid into a liquid product that controls the concentration of CO and CO2 in the fermentation vessel. The process charges the feed gas stream and a recycle gas stream to the fermentation vessel and an off-gas stream collects above the fermentation liquid. The off-gas stream flows to a gas injector that uses a recycle liquid as the motive fluid to mix the off-gas with the recycle liquid into a gas-liquid dispersion. Contact of the recycle liquid with the off-gas absorbs CO2 to provide the recycle stream. A gas separation vessel separates the remainder of the off-gas into the recycle gas. Mixing the recycle gas with the gas input stream dilutes the concentration of CO to lower the CO concentration in the fermentation vessel. Separated recycle liquid flows to a CO2 stripper for removal of CO2.

    摘要： The efficient production of ethanol from low-cost biomass (e.g., corn, sugar beets, sugar cane, switchgrass and/or paper) has become increasingly important in making ethanol competitive with gasoline and decreasing the United States' dependence on foreign oil. For example, to reduce the cost of transporting biomass to ethanol production facilities, mobile systems for producing ethanol from biomass are provided. Also provided are small-scale ethanol production facilities. For example, instead of transporting biomass to the production facility, the facility is transported to the biomass or is located nearby the source of the biomass. The ethanol production facilities or components thereof may be transported via land, water, or air. Production of other products, such as hydrocarbons, natural gas, hydrogen gas, plastics, polymers, and proteins, can also be made by the methods and facilities. Any product described herein can be made in finished form or un-finished form and moved, e.g., to a fixed facility, e.g., fixed production facility.
