Latest Patents

Subrata Sen holds a patent for a process titled "Process for liquefaction of lignocellulosic biomass." This patent describes methods and systems that improve the liquefaction of lignocellulosic biomass. The methods involve reacting a lignocellulosic biomass slurry under mild conditions for a short duration, resulting in a first reaction mixture with reduced viscosity. This mixture is substantially free of levulinic acid and hydroxymethylfurfural. The process further separates the mixture into solid and liquid fractions, with the solid fraction primarily containing lignin and the liquid fraction rich in hemicellulose and cellulose. Notably, this method prevents or eliminates the formation of tar and char, making it a valuable advancement in biomass processing.
