Enzymatic Bleaching of Wood Pulp
The dark colour of kraft pulp after the wood chips have been heated at high temperature with NaOH solution is caused by lignin (a complex phenolic polymer) still attached to the cellulose fibres. Traditionally this pulp is treated with chlorine to bleach the pulp to make it suitable for paper making. Unfortunately this leads to the formation of some potentially toxic chlorophenolic compounds of...
متن کاملEffects of Some Wood Chip Properties on Pulp Quality
A series of TMP experiments were performed at CIPP’s TMP pilot plant, and some pulp properties were measured. By comparing chip and pulp properties, and using projections to latent structures (PLS) analysis, we were able to demonstrate that on-line CMS measurements can be used to predict some pulp properties. It should be pointed out that the focus of this paper is to show how CMS measurements ...
متن کاملSimulating the Dynamics of Flexible Wood Pulp Fibres in Suspension
We investigate the dynamics of a flexible, elastic fibre, suspended in a fluid and subjected to a 3D shear flow. Simulations are performed using the “Immersed Boundary Method,” and are distinguished by their ability to capture the hydrodynamic interaction between the fluid and fibre, as well as the detailed structure of the individual fibres. Suspensions of flexible fibres are encountered in ma...
متن کاملRaman Spectroscopic Characterization of Wood and Pulp Fibers, Chapter 2
This chapter reviews applications of Raman spectroscopy in the field of wood and pulp fibers. Most of the literature examined was published between 1998 and 2006. In addi tion to introduction, this chapter contains sections on wood and components, mechanical pulp, chemical pulp, modified/treated wood, cellulose I crystallinity of wood fibers, and the “self-absorption” phenomenon in near-infrar...
متن کاملSwitchable ionic liquids enable efficient nanofibrillation of wood pulp
Use of switchable ionic liquid (SIL) pulp offers an efficient and greener technology to produce nanofibers via ultrafine grinding. In this study, we demonstrate that SIL pulp opens up a mechanically efficient route to the nanofibrillation of wood pulp, thus providing both a low cost and chemically benign route to the production of cellulose nanofibers. The degree of fibrillation during the proc...
