Methods, reactor systems, and catalysts are provided for converting in a continuous process biomass to fuels and chemicals, including methods of converting the water insoluble components of biomass, such as hemicellulose, cellulose and lignin, to volatile COoxygenates, such as alcohols, ketones, cyclic ethers, esters, carboxylic acids, aldehydes, and mixtures thereof. In certain applications, the volatile COoxygenates can be collected and used as a final chemical product, or used in downstream processes to produce liquid fuels, chemicals and other products.

Production of chemicals and fuels from biomass

The present invention provides methods, reactor systems and catalysts for converting biomass and biomass-derived feedstocks to Chydrocarbons 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.

Production of distillate fuels from biomass-derived polyoxygenates

The present invention includes improved systems and methods for producing biomass-derived feedstocks for biofuel and biochemical manufacturing processes. The systems and methods use components that are capable of transferring relatively high concentrations of solid biomass utilizing pressure variations between vessels, and allows for the recovery and recycling of heterogeneous catalyst materials.

Apparatus and method for converting biomass to feedstock for biofuel and biochemical manufacturing processes

Described are methods, reactor systems, and catalysts for converting biomass to fuels and chemicals in a batch and/or continuous process. The process generally involves the conversion of water insoluble components of biomass, such as hemicellulose, cellulose and lignin, to volatile COoxygenates, such as alcohols, ketones, cyclic ethers, esters, carboxylic acids, aldehydes, and mixtures thereof. In certain applications, the volatile COoxygenates can be collected and used as a final chemical product, or used in downstream processes to produce liquid fuels, chemicals and other products.

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.
