Production of a cellulosic substrate susceptible to enzymatic hydrolysis from prehydrolyzed barley husks

open access: yesAgricultural and Food Science, 2008
An effective process for the chemical-biotechnological utilization of barley husks is reported. A first treatment with sulfuric acid (prehydrolysis) allowed the solubilization of hemicelluloses to give xylose-containing liquors (suitable to make ...

Acetosolv delignification of marabou (Dichrostachys cinerea) wood with and without acid prehydrolysis

open access: yes, 2011
The chemical composition of marabou (Dichrostachys cinerea) wood and its treatment with acetic acid were investigated. Two different treatment approaches, direct acetosolv and combined acid prehydrolysis/acetosolv, were evaluated.

PREPARATION OF BAMBOO DISSOLVING PULP FOR TEXTILE PRODUCTION; PART 1. STUDY ON PREHYDROLYSIS OF GREEN BAMBOO FOR PRODUCING DISSOLVING PULP

open access: yesBioResources, 2011
Prehydrolysis was used as the first treatment of bamboo materials for producing high dissolving pulp for textile applications. In this paper, green bamboo (Dendrocalamopsis oldhami) was hydrolyzed in water, and the hydrolysis process was optimized.

Continuous Prehydrolysis in Sulfate Process for Preparation of Dissolving Pulp

open access: yesJAPAN TAPPI JOURNAL, 1959
In the preparation of dissolving sulfate pulp by the conventional batch system, the digestion is about three cycles per day, and the acid treatment (prehydrolysis) and alkaline cooking (sulfate cooking) are both carried out in a single digester. This process could be improved markedly by separating the prehydrolysis process from the alkaline cooking ...
