Processes for catalytic conversion of lignin to liquid bio-fuels and novel bio-fuels

InactiveUS20080050792A1Increase productionAcceptable processing conditionBiofuelsSolid fuelsLiquid productLignin degradation
Processes for conversion of lignin to liquid products such as bio-fuels and fuel additives are disclosed and described. A process for conversion of a lignin material to bio-fuels can include subjecting the lignin material to a base catalyzed depolymerization reaction to produce a partially depolymerized lignin. The partially depolymerized lignin can then be subjected to a stabilization / partial hydrodeoxygenation reaction to form a partially hydrodeoxygenated product. Following partial hydrodeoxygenation, the partially hydrodeoxygenated product can be reacted in a hydroprocessing step to form a bio-fuel. Each of these reaction steps can be performed in single or multiple steps, depending on the design of the process. The production of an intermediate partially hydrodeoxygenation product and subsequent reaction thereof can significantly reduce or eliminate reactor plugging and catalyst coking. A variety of useful bio-fuels such as fuels, fuel additives, and the like, including gasoline and jet or rocket fuels are describe which can be readily produced from renewable lignin materials in an improved conversion process.

Production of liquid alkanes in the jet fuel range (c8-c15) from biomass-derived carbohydrates

Described is a method for making a composition comprising alkanes. The composition is suitable for use as a liquid transportation fuel in general, and jet fuel in particular. The method includes dehydrating a feedstock solution comprising a carbohydrate, in the presence of an acid catalyst, to yield at least one furan derivative compound, in a reaction vessel containing a biphasic reaction medium: an aqueous reaction solution and a substantially immiscible organic extraction solution. The furan derivative compound is then subjected to a self-aldol condensation reaction or a crossed-aldol condensation reaction with another carbonyl compound to yield a beta-hydroxy carbonyl compound and / or an alpha-beta unsaturated carbonyl compound. The beta-hydroxy carbonyl and / or alpha-beta unsaturated compounds are then hydrogenated to yield a saturated or partially saturated compound, followed by hydrodeoxygenation (e.g., dehydrating and hydrogenating) of the saturated or partially saturated compound to yield a composition of matter comprising alkanes.
