A method and integrated reactor system are provided for producing one or more organic acids, organic acid degradation compounds, and combinations thereof, from various types of biomass, including sludge from a pulp and paper mill.

Method for producing organic acids and organic acid degradation compounds from biomass

Methods and systems are provided for improved liquefaction of a lignocellulosic biomass. The methods include reacting a lignocellulosic biomass slurry at mild conditions for a short period to produce a first reaction mixture having a reduced viscosity as compared to the lignocellulosic biomass slurry and that is substantially free of levulinic acid and hydroxymethylfurfural. The methods further include separating the first reaction mixture into a solid fraction and a liquid fraction, the solid fraction having a majority of lignin from the lignocellulosic biomass slurry and the liquid fraction having a majority of hemicellulose and greater than about 30% by weight of cellulose from the lignocellulosic biomass slurry. The method advantageously prevents or eliminates the formation of tar and/or char.

Process for liquefaction of lignocellulosic biomass

A method for producing levulinic acid from lignocellulosic biomass comprising hemicellulose including one or more six carbon chain compound precursors comprises the steps of hydrolyzing the lignocellulosic biomass to form a first phase comprising partially hydrolyzed lignocellulosic biomass including cellulose and lignin and a second phase comprising one or more five carbon chain sugars and one or more six carbon chain sugars from degradation of the hemicellulose, separating the first phase from the second phase, and converting at least a portion of the one or more six carbon chain sugars to levulinic acid.

Method for producing levulinic acid from lignocellulosic biomass

A method and integrated system for producing levulinic acid from the sludge of a pulp and paper mill and other lignocellulosic biomass is provided.

Method for producing levulinic acid from sludge and lignocellulosic biomass

An embodiment configured according to principles of the invention includes a plate defining a hexagon having a base parallel with joint between concrete slabs. Another embodiment includes a hexagon-shaped plate having a first portion and a second portion, and a form having a slot configured to closely receive the second portion.
