Extraction of lignin from different sources of biomass using organosolv pretreatment and determination of its physical and chemical behaviour

Lignocellulosic biomass is the natural resources that are produced as the by-product from agricultural activities. It is composed of three main components which are cellulose, hemicellulose and lignin. Lignin is the second most abundant organic polymer after cellulose and its roles is providing mech...
