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.

Method and systems for making distillate fuels from biomass

The present invention provides processes for catalytically converting biomass to oxygenated compounds suitable for use in bioreforming processes.

Catalytic biomass deconstruction

The present invention provides catalysts, methods, and reactor systems for converting oxygenated hydrocarbons to oxygenated compounds. The invention includes methods for producing cyclic ethers, monooxygenates, dioxygenates, ketones, aldehydes, carboxylic acids, and alcohols from oxygenated hydrocarbons, such as carbohydrates, sugars, sugar alcohols, sugar degradation products, and the like, using catalysts containing Group VIII metals. The oxygenated compounds produced are useful in the production of liquid fuels, chemicals, and other products.

Catalysts for hydrodeoxygenation of oxygenated hydrocarbons

Methods, catalysts, and reactor systems for producing in high yield aromatic chemicals and liquid fuels from a mixture of oxygenates comprising di- and polyoxygenates are disclosed. Also disclosed are methods, catalysts, and reactor systems for producing aromatic chemicals and liquid fuels from oxygenated hydrocarbons such as carbohydrates, sugars, sugar alcohols, sugar degradation products, and the like; and methods, catalysts, and reactor systems for producing the mixture of oxygenates from oxygenated hydrocarbons such as carbohydrates, sugars, sugar alcohols, sugar degradation products, and the like. The disclosed catalysts for preparing the mixture of oxygenates comprise a Group VIII metal and a crystalline alumina support.

Production of aromatics from di- and polyoxygenates

The present invention provides processes for catalytic deconstruction of biomass using a solvent produced in a bioreforming reaction.

Organo-catalytic biomass deconstruction

The present invention provides processes, methods, and systems for converting biomass-derived feedstocks to liquid fuels and chemicals. The method generally includes the reaction of a hydrolysate from a biomass deconstruction process with hydrogen and a catalyst to produce a reaction product comprising one of more oxygenated compounds. The process also includes reacting the reaction product with a condensation catalyst to produce Ccompounds useful as fuels and chemicals.
