Abstract:
The present invention provides methods, reactor systems, and catalysts for converting in a continuous process biomass to less complex oxygenated compounds for use in downstream processes to produce biofuels and chemicals. The invention includes methods of converting the components of biomass, such as hemicellulose, cellulose and lignin, to water-soluble materials, including lignocellulosic derivatives, cellulosic derivatives, hemicellulosic derivatives, carbohydrates, starches, polysaccharides, disaccharides, monosaccharides, sugars, sugar alcohols, alditols, polyols, diols, alcohols, ketones, cyclic ethers, esters, carboxylic acids, aldehydes, and mixtures thereof, using hydrogen and a heterogeneous liquefaction catalyst.
Abstract:
The present invention provides methods, reactor systems, and catalysts for increasing the yield of aromatic hydrocarbons produced while converting alkanols to hydrocarbons. The invention includes methods of using catalysts to increase the yield of benzene, toluene, and mixed xylenes in the hydrocarbon product.
Abstract:
The present invention provides methods, reactor systems and catalysts for converting biomass and biomass-derived feedstocks to C8+ hydrocarbons using heterogenous catalysts. The product stream may be separated and further processed for use in chemical applications, or as a neat fuel or a blending component in jet fuel and diesel fuel, or as heavy oils for lubricant and/or fuel oil applications.
Abstract:
The present invention provides processes for catalytically converting biomass to oxygenated compounds suitable for use in bioreforming processes.
Abstract:
Disclosed are methods for generating propylene glycol, ethylene glycol and other polyols, diols, ketones, aldehydes, carboxylic acids and alcohols from biomass using hydrogen produced from the biomass. The methods involve reacting a portion of an aqueous stream of a biomass feedstock solution over a catalyst under aqueous phase reforming conditions to produce hydrogen, and then reacting the hydrogen and the aqueous feedstock solution over a catalyst to produce propylene glycol, ethylene glycol and the other polyols, diols, ketones, aldehydes, carboxylic acids and alcohols. The disclosed methods can be run at lower temperatures and pressures, and allows for the production of oxygenated hydrocarbons without the need for hydrogen from an external source.
