Integrated preparation of functional lignin nanoparticles and levulinic acid directly from the pre-hydrolysis liquor of poplar wood

International Journal of Biological Macromolecules
The pre-hydrolysis liquor (PHL) produced during pulp dissolution and biomass refining is mainly composed of hemicellulose and lignin, and it is a potential source for production of value-added materials and platform chemicals; however, their utilization has been a serious challenge.

Removal of inhibitors from pre-hydrolysis liquor of kraft-based dissolving pulp production process using adsorption and flocculation processes

Bioresource Technology, 2012
A process for removing inhibitors from pre-hydrolysis liquor (PHL) of a kraft-based dissolving pulp production process by adsorption and flocculation, and the characteristics of this process were studied. In this process, industrially produced PHL was treated with unmodified and oxidized activated carbon as an absorbent and polydiallyldimethylammonium ...

Kinetics of furfural production from pre-hydrolysis liquor (PHL) of a kraft-based hardwood dissolving pulp production process

Biomass and Bioenergy, 2014
Abstract The kinetics of C-5 sugars (xylose/xylan) conversion to furfural in an industrial pre-hydrolysis liquor (PHL) in both acetic acid (HAc)-catalyzed system and sulfuric acid (H 2 SO 4 )-catalyzed system, were determined in a temperature range of 150–190 °C.
