Cellulosic Fibers from Miscanthus
Journal Title: BULETINUL INSTITUTULUI POLITEHNIC DIN IASI, CHIMIE SI INGINERIE CHIMICA - Year 2017, Vol 63, Issue 3
Abstract
Miscanthus is an important biomass crop and has an important role in the sustainable production of renewable fuels and chemicals. It is currently used as a source of heat and electricity, or converted into biofuel products. There are many possibilities to valorize Miscanthus crops: combustion, gasification and pyrolysis for energy; liquefaction and hydrolysis for chemicals; delignification for cellulosic fibers. Chemical composition of Miscanthus is encouraging regarding its cellulose and lignin content, making them suitable for delignification. Miscanthus pulp can be obtained by usual delignification processes, among them soda cooking being very attractive. Pulps having different yields and lignin content were obtained by suitable choosing of the cooking parameters: NaOH addition, time and temperature. The strength properties of pulp mainly depended on its lignin content. Lignin-rich pulps show high compressive strength, being appropriate in paper manufacturing for corrugated board production.
