Abstract: A system and method for generating a water-soluble mixture of oligosaccharides for facile conversion to fermentable sugars is provided. The method describes crushing, grinding, or both, a mixture of a cellulose feedstock and a solid acid catalyst, under pressure to induce a solid-solid interaction between the cellulosic feedstock and the solid acid catalyst to induce a chemical reaction to produce a grinded mixture, wherein the crusher assembly comprises rollers, introducing water to separate the grinded mixture into solids and a solution, wherein the solution comprises the oligosaccharides and enzymatically converting the solution to fermentable sugars.

Abstract: Alternative gasoline, diesel fuel, marine diesel fuel, jet fuel, and flexible fuel compositions are disclosed. The compositions include an alcohol and/or a glycerol ether or mixture of glycerol ethers, which can be derived from renewable resources. When combined with gasoline/ethanol blends, glycerol ethers can reduce the vapor pressure of ethanol and increase fuel economy. Added to diesel fuel/alcohol blends, glycerol ethers improve the cetane value of the blends. In jet fuel, glycerol ethers can replace all or part of conventional deicing additives, lowering skin toxicity, and glycerol ethers ability to reduce particulate emissions can lower the appearance of contrails. Used in marine diesel, the reduction in particulate emissions can be environmentally significant. In another embodiment, the alternative compositions comprise gasoline, ethanol, and n-butanol, and in one aspect, the ethanol and/or n-butanol can be derived from renewable resources.

Abstract: A combined anaerobic digester system and gas-to-liquid system is disclosed. The anaerobic digester requires heat, and produces methane. The gas-to-liquid system produces heat, and converts methane to higher-value products, including methanol and formaldehyde. As such, the combination of the two systems results in significant savings in terms of capital and operating expenses. A process for producing bio-formaldehyde and bio-formalin from biogas is also disclosed.

Abstract: A reactor system includes plural batch-cyclic reduction/oxidation (redox) reactors. One reactor is operated in fuel mode while another is operated in air mode, and vice-versa. For each reactor in air mode, air is introduced via air-only tuyeres and via fuel-air tuyeres to oxidize oxidation particles. For each reactor in fuel mode, fuel is introduced via the reactor's fuel-air tuyeres and not via its air-only tuyeres. As a result, air is introduced at a higher rate than fuel is introduced so that the oxidation rate can match the reduction rate. Thus, for example, as few as two reactors can be used for continuous power generation without having to shuttle oxidation particles between reactors.
