Abstract: Technical lignin compositions and pyrolysis methods for forming such technical lignin compositions from pyrolyzed biomass are provided. The technical lignin compositions can include at least about 50 wt % phenolic polymers and/or at least about 75 wt % combined phenolic monomers and phenolic polymers. In some aspects, less than about 50 wt % of the linkages between benzylic units in the phenolic polymers and/or in the composition can correspond to β-O-4 linkages. At least about 50 wt% of the hydroxyl groups in the composition can correspond to phenolic hydroxyl groups. At least about 60 wt % of the phenolic hydroxyl groups and/or phenolic ether groups can correspond to phenolic hydroxyl groups and/or phenolic ether groups in an ortho position relative to at least one substituent.

Abstract: Systems and methods are provided for processing a feed derived from a renewable source to form oligomerized compounds corresponding to waxes, ketone waxes, and/or lubricant boiling range compounds. The oligomerized compounds derived from the renewable source can have various novel properties relative to waxes and/or lubricant boiling range compounds derived from mineral sources or derived from renewable sources in a conventional manner. The oligomerized compounds can be derived from a renewable source including fatty acids and/or fatty acid derivatives, such as glycerides (including triglycerides) and fatty amides. Optionally but preferably, at least a portion of the fatty acids and/or fatty acid derivatives can include olefinic bonds.

Abstract: Methods are provided for biological conversion of anhydrosugars, such as anhydrosugars found in a pyrolysis oil, to fatty acid alkyl esters. The methods can include use of a genetically modified Escherichia coli (E. coli) bacteria that can convert levoglucosan and/or other anhydrosugars into fatty acid alkyl esters without requiring formation and conversion of an intermediate compound external to the bacteria. Optionally, the methods can be used in combination with methods for production and/or separation of increased amounts of levoglucosan from pyrolysis of biomass.

Abstract: Systems and methods are provided for pretreatment and upgrading of crude bio oils for further processing and/or use as fuel products. Crude bio oils can be treated by one or more of flash fractionation and thermal cracking to generate fractions suitable for further processing, such as further hydroprocessing. Blending of crude bio oil fractions with mineral feeds can also be used to reduce metals contents to levels suitable for refinery processing.
