Processes and reactor systems are provided for the conversion of oxygenated hydrocarbons to hydrocarbons, ketones and alcohols useful as liquid fuels, such as gasoline, jet fuel or diesel fuel, and industrial chemicals. The process involves the conversion of mono-oxygenated hydrocarbons, such as alcohols, ketones, aldehydes, furans, carboxylic acids, diols, triols, and/or other polyols, to C₄₊ hydrocarbons, alcohols and/or ketones, by condensation. The oxygenated hydrocarbons may originate from any source, but are preferably derived from biomass.

Processes and reactor systems are provided for the conversion of oxygenated hydrocarbons to paraffins useful as liquid fuels. The process involves the conversion of water soluble oxygenated hydrocarbons to oxygenates, such as alcohols, furans, ketones, aldehydes, carboxylic acids, diols, triols, and/or other polyols, followed by the subsequent conversion of the oxygenates to paraffins by dehydration and alkylation.

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.

Two classes of solvents, organic esters and diols and triols, help to reduce bleed between black (pigment-containing) inks and color (water-soluble dye-based) inks when used in formulating inks that contain self-dispersed pigments. The solvents help self-dispersed pigments to agglomerate by producing successful mutual collisions when the electrostatic potential is reduced with positively charged color inks. It appears that these solvents may be changing the dielectric constant of the ink, thereby reducing the repulsion potential of the pigment particles themselves.
