    Volume 6 Chemical Pulping Part 2, Recovery of Chemicals and Energy. Book editor: Panu Tikka, Professor, SciTech Service Oy Ltd, Espoo, Finland. The book covers kraft pulp mill technology from fibre line spent liquor — black liquor — to the recovered active cooking chemical — white liquor — and energy in the form of steam and electricity. AbstractKraft pulps from acacia hybrid, Acacia mangium of 8 years old and Acacia auriculiformis of 6, 8 and 10 years old were pre-treated with oxygen, peroxyformic acid and acid treatment prior to bleaching. The kappa number reduction was 52–63 % by oxygen delignification, 31–35 % by peroxyformic acid (PFA) pre-treatment and 11–13 % by acid pre-treatment.

    Abstract. The reactions between chlorine dioxide and the residual lignin in oxygen-bleached softwood kraft pulps have been studied. In a first series, isolated lignin samples have been subjected to chlorine dioxide oxidation at different pH values and subsequently analysed by oxidative degradation and elemental analysis.   In: Proceedings of the 5th international conference on biotechnology in the pulp and paper industry, Kyoto, Japan, 27–30 May , p Google Scholar Suurnakki A, Tenkanen M, Buchert J, Viikari L () Hemicellulases in the bleaching of chemical pulps.

Welcome to the edition of the International Pulp Bleaching Conference. This conference is dedicated to all chemical and engineering aspects of pulp bleaching.

Held every three years, it is the most important meeting on this subject and allows hundreds of individuals involved in pulp bleaching to meet, learn and exchange with one another. International Pulp Bleaching Conference: June, Hyatt Regency Hotel, Vancouver, British Columbia by International Pulp Bleaching Conference (Book).

Bleaching of wood pulp is the chemical processing of wood pulp to lighten its color and whiten the pulp.

The primary product of wood pulp is paper, for which whiteness (similar to, but distinct from brightness) is an important characteristic. These processes and chemistry are also applicable to the bleaching of non-wood pulps, such as those made from bamboo or kenaf.

Authors: Alan W. Rudie, Ph.D., and Peter W. Hart, Ph.D. Previous editions of The Bleaching of Pulp have provided comprehensive information on the technology used to bleach wood pulps.

The 5th edition will continue this tradition as the premiere industry text on bleaching technologies but will be more focused on the modern industrial processes with less emphasis on fundamental science.

Montreal. Cited by: 1. The benefits obtained by enzymes are dependent on the chemical bleaching sequence used as well as on the residual lignin content of pulp.

The main goals in the enzyme-aided bleaching of kraft pulps have been the reduction of consumption of chlorine chemicals in the bleaching process and consequently lowering the AOX of the effluents. Material “TAPPI Proceedings.

Abstract. During sequential bleaching operations, pulp fiber properties are gradually changed due to mechanical and chemical treatments. In this study, the correlations between pulp or fiber properties such as kappa number, viscosity, total charge, fiber length, and zero-span tensile strength as well as Scott bond of elemental chlorine free (ECF) bleached softwood kraft pulps was investigated.
