Description

The chemical composition of the main constituents of the wood and other biomass as well as its main structural features and properties. Main principles of isolation and analysis of different components of biomass. The different stages of the sulfate 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 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 sulfate process and other delignification processes.


Working life skills

After completing the course, the student will master the structure and chemistry of lignocelluloses and be able to discuss the chemical differences between wood and other lignocelluloses, as well as sulfate pulping process.

Additional information

The course is lectured in 2025-2026 and 2027-2028. The course can be taken by book exam in 2024-2025 ja 2026-2027. Lectures are in Finnish.
