Effects of Metal Chlorides on the Solubility of Lignin in the Black Liquor of Prehydrolysis Kraft Pulping

open access: yesBioResources, 2014
The effects of CaCl2, MgCl2, FeCl3, NaCl, and AlCl3 on the solubility of lignin in the prehydrolysis kraft black liquor of Masson pine were studied using a focused-beam reflectance measurement (FBRM) instrument and UV spectra.

Influence of Pre-Hydrolysis on the Chemical Composition of Prunus avium Cherry Seeds

open access: yesAgronomy, 2022
During the industrial processing of sweet cherry fruits, the seeds are considered agricultural waste and must be disposed of, typically through burning. In this context, it is intended to contribute to the scientific development of the ecovalorization of

Purification of cellulosic pulp by hot water extraction [PDF]

open access: yes, 2016
Hot water extraction (HWE) of pulp in a flow-through reactor was evaluated as a method to purify paper-grade pulps. About 50–80 % of the xylan and up to 50 % of the lignin in unbleached birch Kraft pulp was extracted by the HWE without losses in ...

Removal of fermentation inhibitors from pre-hydrolysis liquor using polystyrene divinylbenzene resin

open access: yesBiotechnology for Biofuels, 2020
Background The presence of soluble lignin, furfural and hydroxymethylfurfural (HMF) in industrial pre-hydrolysis liquor (PHL) from the pulping process can inhibit its bioconversion into bioethanol and other biochemicals.
