Abstract:
The present disclosure provides an organosolv biorefining process. The present process comprises treating a lignocellulosic biomass in the presence of a solvent and under certain conditions to separate at least a part of the lignin from the biomass.
Abstract:
The present disclosure provides the use of a biomass-derived aromatic material as a sorbent for naphthenic acid. For example, the biomass-derived aromatic material may be a lignin derivative such as an Organsolv lignin derivative. The present disclosure further provides a method for reducing the amount of naphthenic acid in a substance, said method comprising applying a suitable amount of biomass-derived aromatic sorbent to the substance containing naphthenic acid; and allowing the sorbent to interact with the substance to remove at least a portion of the naphthenic acid from the substance.
Abstract:
The present disclosure provides an organosolv process. The present process comprises treating a lignocellulosic biomass in the presence of a solvent and under certain conditions to separate at least a part of the lignin from the biomass.
Abstract:
A wax composition comprising a lignin derivative wherein the derivative has a total hydroxyl content of from about 0.1 mmol/g to about 7 mmol/g.
Abstract:
The present invention provides hardwood derivatives of native lignin having an aliphatic hydroxyl content of from about 5.2 mmol/g to about 7 mmol/g. Surprisingly, it has been found that consistent and predictable antioxidant activity may be provided by selecting for derivatives of native lignin having a certain aliphatic hydroxyl content.
Abstract:
This present invention relates to an organosolv process for the extraction of materials from lignocellulosic biomass. This invention further relates to the chemicals and their derivatives extracted from biomass, uses, apparatus, methods, and the like. In an embodiment of the invention the material extracted from the lignocellulosic biomass is levulinic acid.
Abstract:
The present disclosure provides the use of lignin derivatives for remediation of oil discharge such as, for example, crude or refined oil spills. The present disclosure provides methods of remediating oil discharges such as, for example, accidental discharge into a marine environment.
Abstract:
The present disclosure provides a binder composition comprising a diisocyanate and a derivative of native lignin. The derivative of native lignin is treated such that it is characterized by the aliphatic hydroxy content. The binder may be used in an adhesive system comprising: a. a resin comprising at least about 30% by weight of phenol-formaldehyde resin and at least about 30% by weight of derivative of native lignin; and b. an isocyanate based binder.
Abstract:
The present disclosure provides derivatives of native lignin having a certain carbon content and/or a certain alkoxy content and their use in carbon fibres.
Abstract:
The present invention provides derivatives of native lignin having an ethoxy content of 0.45 mmol/g or greater. Surprisingly, it has been found that phenolic resins comprising derivatives of native lignin having ethoxy contents have acceptable performance characteristics such as bond strength.
