advanced global cultural development. Pulping is a key step in the conversion of fiber raw …

The chemical industry is being forced to evaluate new strategies for more effective utilization
of renewable feedstocks to diminish the use of fossil resources. In this literature review, the …

The feasibility of thermochemical biomass conversion technologies can be improved if value-
added applications for all fractions can be developed. One of such approaches is the use of …

Napier grass is a promising energy source on account of its strong adaptability and high
productivity. Herein, an O 2-aided alkaline pretreatment with mild operating conditions was …

The aim of this study was to isolate lignin from spruce wood with an accelerated solvent
extractor (Dionex ASE 350) using low concentration alkali solutions. Two concentrations of …

The purpose of the impregnation stage is to ensure that cooking chemicals reach all parts of
the chips. However, as alkali comes into contact with wood, reactions take place, which alter …

A pulp yield increase up to 2% can be achieved by impregnation with a liquor containing 2
M effective alkali (EA) concentration instead of 1 M. The yield increase is due to higher …

Wheat straw and okra stalk were studied to evaluate their potential use for integrated
lignocellulosic biorefining. Besides chemical pulp, a wide spectrum of value-added by …

In the present work, okra stalk (Abelmoschus esculentus) was chemically characterized to
evaluate its appropriate exploitation as a biorefinery feedstock. The chemical composition of …
