Mechanisms and Defiberation Point of Pinus Kesiya Diethanolamine Pulping

Abstract:

Mechanisms and defiberation point of pinus kesiya diethanolamine pulping were analyzed in this paper. The results show that the delignification of diethanolamine cooking is divided into three stages: the initial delignification stage, which is from the beginning of heating to 170°C, and its delignification rate is about 30%; the bulk delignification stage, which is from 170°C to 200°C for 60min with the total delignification rate about 90%; the supplementary delignification stage, which is from 200°C for 60min to the end of cooking, and its delignification rate is more than 97%. And the defiberation point is at 200°C for 30min nearby.
