Sugar cane bagasse prehydrolysis using hot water [PDF]

open access: yesBrazilian Journal of Chemical Engineering, 2012
Results are presented on the hot water prehydrolysis of sugar cane bagasse for obtaining ethanol by fermentation. The experimental study consisted of the determination of the effect of temperature and time of prehydrolysis on the extraction of hemicelluloses, with the objective of selecting the best operating conditions that lead to increased yield of ...

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 xylan content on the oxygen delignification performance of eucalypt kraft pulps as studied using prehydrolysis and xylanase treatments [PDF]

open access: yesBioResources, 2012
Common metrics for evaluating the efficiency of oxygen delignification include the kappa number and Klason lignin content. As a change in xylan content often leads to a change in HexA content, the kappa number must be corrected for the HexA contribution ...

Prehydrolysis and organosolv delignification process for the recovery of hemicellulose and lignin from beech wood

open access: yes, 2022
Art. 100506Beechwood was fractionated using a two-stage process approach followed by enzymatic hydrolysis of the obtained pulp. Where most of the xylan was recovered by the prehydrolysis in the first stage, while the most lignin was recovered in the ...

Kinetic Modeling of Hardwood Prehydrolysis. Part III. Water and Dilute Acetic Acid Prehydrolysis of Southern Red OAK [PDF]

open access: yes, 2007
The hemicelluloses in wood are more readily hydrolyzed than is cellulose. Because it is advantageous to process the hemicellulose sugars separately from the glucose obtained from the cellulose, most processes for utilizing wood as a source of chemicals ...

Kinetic Modeling of Hardwood Prehydrolysis. Part II. Xylan Removal by Dilute Hydrochloric Acid Prehydrolysis [PDF]

open access: yes, 2007
Knowledge of prehydrolysis kinetics has applicability to the design, development, and modeling of processes to separate wood into its basic chemical constituents (i.e., cellulose, hemicellulose, and lignin).

Effect of Liquid to Solid Ratio on Autohydrolysis of Eucalyptus globulus Wood Meal

open access: yesBioResources, 2014
Autohydrolysis of Eucalyptus globulus both with and without the addition of 5 g/L formic acid was explored for different liquid-to-solid (L/S) ratios at 150 ºC for 100 min.

The influence of pre-hydrolysis on the delignification of Hornbeam wood [PDF]

open access: yesتحقیقات علوم چوب و کاغذ ایران, 2018
In this research, the influence of two temperatures (60 and 90°C) and three dosages of sodium hydroxide (5, 7.5 and 10%, based on the dry weight) on hornbeam wood chips alkaline pre-hydrolysis and soda pulping was studied.
