Common aspects of acid prehydrolysis and steam explosion for pretreating wood

Bioresource Technology, 1991
Abstract The initial rate of hydrolysis using cellulase from Trichoderma reesei for various wood samples is directly proportional to the surface area available to the enzyme. Both dilute acid hydrolysis in a continuous flow reactor or autohydrolysis in a steam exploder are similar pretreatment methods in that they increase the pore volume of the ...

SO2 prehydrolysis for high yield ethanol production from biomass

Applied Biochemistry and Biotechnology, 1988
The advantages of the use of SO2 in steam pretreatment are described. Two different large scale continuous reactors, the Stake and the Wenger, have been used for this purpose. Pine, aspen and corn stover were prehydrolysed by SO2 in these reactors and hydrolysed by enzymes.

Saccharification of douglas‐fir wood by a combination of prehydrolysis and pyrolysis

Journal of Applied Polymer Science, 1982
AbstractA process has been investigated for the saccharification of wood, involving prehydrolysis, lignocellulose pyrolysis, and tar hydrolysis. In this process, ground wood was first prehydrolyzed to remove the more readily hydrolyzable hemicelluloses.

Prehydrolysis of xylan in culm of Sasa kurilensis with dilute sulphuric acid

European Journal of Wood and Wood Products, 2009
To prepare a substrate for microbial conversion of xylose into xylitol, the culm of Sasa kurilensis was hydrolysed with dilute sulphuric acid. A fermentable substrate with a relatively high xylose concentration (21.9 g L−1) was obtained by hydrolysis with 2% sulphuric acid with a liquid to solid ratio of 10 : 1 at 121°C for 1 h.

Lignin Changes during Prehydrolysis of Lignocellulosic Biomass for Cellulose Bioconversion: A Review

Biomacromolecules
The bioconversion of a lignocellulosic biomass presents significant challenges due to its complex structure. Various pretreatments have been explored to enhance biomass accessibility for efficient fractionation. Prehydrolysis, known for its environmental friendliness and promising benefits, emerges as an effective strategy.
