Description

The chemical composition of the main constituents of the wood and other biomass as well as its main structural features and properties. Isolation and analysis of different components of biomass. The different stages of the sulphate cooking process and recovery of cooking chemicals. In addition, the main features of other pulping processes such as organosolv and sulfite processes are considered.

Learning outcomes

After completing this course the student will understand in detail the structures of Softwood and Hardwood materials and their Special Features as well as the main chemical compositions of other lignocellulosic biomasses. The student outlines a variety of possibilities for the separation and analysis (characterization) of the major components of lignocelluloses. The student will master the chemistry of the different stages of the sulphate process and other delignification processes.


Working life skills

After completing the course, the student will master the structure and chemistry of trees and be able to discuss the chemical differences between wood and other lignocelluloses.

Additional information

The course is lectured in 2021-2022. The course can be taken by book exam in 2020-2021 and 2022-2023.
