    Abstract: Methods for producing low oxygen biomass-derived pyrolysis oil are provided. Starting biomass-derived pyrolysis oil is deoxygenated by exposing the biomass-derived oil to a first catalyst in the presence of hydrogen-containing gas at first hydroprocessing conditions to produce a partially deoxygenated biomass-derived pyrolysis oil. The first catalyst has a neutral catalyst support. The partially deoxygenated biomass-derived pyrolysis oil is exposed to a second catalyst in the presence of additional hydrogen-containing gas at second hydroprocessing conditions to produce a hydrocarbon product. The biomass-derived pyrolysis oil may be esterified prior to deoxygenation. A portion of the low oxygen biomass-derived pyrolysis oil is recycled.

    Abstract: Some variations provide a process for producing cellulosic fructose from biomass, comprising: fractionating a biomass feedstock in the presence of an acid catalyst, a solvent for lignin, and water, to produce a liquor containing cellulose-rich solids, lignin, and dissolved hemicellulose; removing the cellulose-rich solids from the liquor; hydrolyzing the dissolved hemicellulose contained in the liquor, to produce a hydrolyzed liquor comprising hemicellulosic monomers; hydrolyzing the cellulose-rich solids to produce glucose, using cellulase enzymes or an acid or base hydrolysis catalyst; enzymatically isomerizing the glucose to fructose, using glucose isomerase enzymes; and recovering the fructose in purified form or in a fructose-glucose solution. The cellulosic fructose produced by the disclosed processes has many uses.

    Abstract: Disclosed is a process for converting bio-oil, wherein the process includes the steps, where a feedstock including bio-oil selected from bio-oils, any fractions of bio-oils and any combinations thereof is subjected to azeotropic distillation with at least one alcohol to yield a liquid component, and subjecting the liquid component to alcoholysis whereby converted bio-oil is obtained. The invention also relates to the use of converted bio-oil, obtainable by the process, as heating oil, as starting material in processes for producing fuels, fuel components, fine chemicals, chemical building-blocks, and solvents.

    Abstract: A bio-oil production process involving torrefaction pretreatment, catalytic esterification, pyrolysis, and secondary catalytic processing significantly reduces yields of reactor char, catalyst coke, and catalyst tar relative to the best-case conditions using non-torrefied feedstock. The reduction in coke as a result of torrefaction was 28.5% relative to the respective control for slow pyrolysis bio-oil upgrading. In fast pyrolysis bio-oil processing, the greatest reduction in coke was 34.9%. Torrefaction at 275° C. reduced levels of acid products including acetic acid and formic acid in the bio-oil, which reduced catalyst coking and increased catalyst effectiveness and aromatic hydrocarbon yields in the upgraded oils. The process of bio-oil generation further comprises a catalytic esterification of acids and aldehydes to generate such as ethyl levulinate from lignified biomass feedstock.

    Abstract: Digesting cellulosic biomass in the presence of a slurry catalyst may reduce degradation product formation, but catalyst distribution and retention can be problematic. Digestion methods can comprise: providing cellulosic biomass solids and a slurry catalyst capable of activating molecular hydrogen in a digestion unit; providing a digestible filter aid in the digestion unit; distributing the slurry catalyst within the cellulosic biomass solids using fluid flow; retaining at least a portion of the slurry catalyst in a fixed location using the digestible filter aid; heating the cellulosic biomass solids in the presence of the slurry catalyst, a digestion solvent, and molecular hydrogen, thereby forming a liquor phase comprising soluble carbohydrates; and performing a catalytic reduction reaction on the soluble carbohydrates within the digestion unit, thereby at least partially forming a reaction product comprising a triol, a diol, a monohydric alcohol, or any combination thereof in the digestion unit.
