Adsorption of lignocelluloses of model pre-hydrolysis liquor on activated carbon
Bioresource Technology, 2013The main objective of this work was to study the adsorption behavior of various components dissolved in the pre-hydrolysis of kraft process on activated carbon. In this work, model prehydrolysis liquor (PHL) solutions (MPHL)s were prepared via mixing various commercially available monosugars, xylan, lignin and furfural; and their adsorption performance

Pre-hydrolysis liquor (PHL) from the kraft-based dissolving pulp process contains large amounts of hemicelluloses, which is usually treated as an effluent and further efforts have to be involved to eliminate the pollution disposal. However, the hemicelluloses-rich PHL is a promising candidate for the production of carbon microspheres via hydrothermal ...

Production of furfural from an industrial pre-hydrolysis liquor
Separation and Purification Technology, 2015Abstract Pre-Hydrolysis Liquor (PHL) produced from the prehydrolysis kraft-based (PHK) dissolving pulp production process can be considered as a potential source for the production of biomaterials and biochemicals. Several dissolved organics such as hemicelluloses, lignin and acetic acid can be recovered and converted to valuable products.

Hemicelluloses in industrially produced pre-hydrolysis liquor (PHL) were precipitated with ethanol. These PHL-derived hemicelluloses (PHL-EH) and a commercial, pure birch wood xylan sample (powder form) (BWX) were bleached using chlorine dioxide (D(0) and D(1)) and hydrogen peroxide (Ep) in the D(0)EpD(1) sequence, and the chemical compositions ...

Simulation analysis of producing xylitol from hemicelluloses of pre-hydrolysis liquor
Chemical Engineering Research and Design, 2014Abstract The pre-hydrolysis liquor (PHL) of the kraft-based dissolving pulp production process is currently sent to the recovery boiler and incinerated. However, PHL contains about 5–8% lignocelluloses that can be utilized in the production of value-added chemicals.

Chitosan as a flocculant for pre-hydrolysis liquor of kraft-based dissolving pulp production process
Carbohydrate Polymers, 2011Abstract In this work, the flocculation concept was employed to recover the dissolved lignocellulosic materials of industrially produced pre-hydrolysis liquor (PHL) using two different molecular weights of chitosan. The analysis revealed the maximum turbidity of 1000 NTU or 1900 NTU via adding 2.2 mg/g low molecular weight (LMW) or 1.7 mg/g high ...
