Organosolv pulping — methods and pulp properties

Biomass, 1987
Abstract Potential benefits of using organic solvents for the delignification of lignocellulosic materials are discussed. Main characteristics of organosolv pulping methods published in the literature are presented and softwood pulp yields and strengths are compared with corresponding values of Kraft and sulphite pulps. Yields of organosolv softwood

Lignin precipitation on the pulp fibers in the ethanol-based organosolv pulping

Colloids and Surfaces A: Physicochemical and Engineering Aspects, 2007
Ethanol pulping of eucalyptus wood chips and wheat straw was conducted to investigate the precipitation of dissolved lignin back onto the fibers in pulping and washing. Results show that a large amount of lignin particles are present on the fibers after pulping and each stage of washing in a four-stage washing sequence, which was identified by both ...

Base-catalyzed organosolv pulping of jute

Journal of Chemical Technology and Biotechnology, 2003
AbstractJute fibers were pulped using a novel caustic soda and ethanol–alkali (EtOH–NaOH) pulping process with the aim of minimizing problems associated with conventional chemical pulping. The effects of reaction conditions on the pulp yield, degree of delignification and selected physical properties were evaluated.

Effect of organosolv and soda pulping processes on the metals content of non-woody pulps

Bioresource Technology, 2008
In this work the effect of different pulping processes (ethyleneglycol, diethyleneglycol, ethanolamine and soda) of tow abounded raw materials (empty fruit bunches - EFB and rice straw) on the ash, silicates and metals (Fe, Zn, Cu, Pb, Mn, Ni and Cd) content of the obtained pulps have been studied. Results showed that pulps obtained by diethyleneglycol

Graft Pulping in Organosolv Systems

Journal of Wood Chemistry and Technology, 1992
ABSTRACT It has been previously demonstrated that free radicals are produced in the delignification of wood. These free radicals can be utilized to initiate grafting of vinyl polymers to the wood pulp. This simultaneous delignification and graft copolymerization has been referred to as graft pulping. The grafting of a variety of vinyl monomers to aspen
