Patent CA-2539095-A1 (CA)
Inventor: TAN ZHENG
IPC: D21H11/16
Filed: 2004-09-22
Abstract: A method for alteration of the morphology of cellulose fibers, particularly softwood fibers, by (a) subjecting the fibers to a metal ion-activated peroxide treatment carried out at a pH of between about 1 and about 9, preferably between 3 and 7, and (b) subjecting the treated fibers to a refining treatment thereby converts SW fibers to HW-like fibers in many respects. The metal ion-activated peroxide treatment has been noted to act on pulp cellulose and hemi-cellulose, causing oxidation and oxidative degradation of cellulose fibers. The chemical treatment of the pulp, taken alone, is not sufficient to attain the desired modification of the morphology of the fibers, however, subsequent refining or like mechanical treatment of the chemically-treated fibers to achieve a given degree of refinement of the fibers requires dramatically less refining energy to achieve a desired end point of refinement and to impart other desirable properties to the pulp. A pulp of modified SW  fibers and a mixture of HW fibers and modified HW fibers are disclosed.

Abstract: The invention relates to a thermodynamic circuit (9) with a working medium comprising at least two substances with non-isothermal evaporation and condensation whereby the working medium can decompose above a given temperature. According to the invention, the heat from heat sources (AG) at temperatures above the decomposition temperature of the working medium may be made useful with little complexity and with high operational security, whereby the heat from the heat source (AG) is transferred in a first step to a hot liquid circuit (4) and, in a second step, from the hot liquid circuit (4) to the circuit (9) with the working medium comprising at least two substances with non-isothermal evaporation and condensation. The heat introduced to the circuit (9) with the working medium comprising at least two substances with non-isothermal evaporation and condensation can be reduced by means of the intermediate hot liquid circuit (4), such that a decomposition of the working medium can be avoided. Furthermore, the circuit (9) with the working medium comprising at least two substances with non-isothermal evaporation and condensation is embodied as a standardised solution for use with differing heat sources each at differing temperatures, whereby matching to the temperature of the heat source (AG) is achieved by means of the intermediate hot liquid circuit (4).
