Cellulose and technology of a paper
The aim of the course:
To get knowledge about wood as a natural material and about isolation of cellulose froma different wood types. The processing of a cellulose to obtain a paper. The production of a paper packaging products and other products based on cellulose.
The program of the course:
1. Wood and wood fibers
2. Chemistry of wood: cellulose, hemicellulose and lignin
3. Technology of cellulose
4. Technology of cellulose from wood
5. Technology of hemicellulose: neutral sulphite process, cold alkaline process
6. Technology of sulphite cellulose: acid process
7. Technology of sulphate cellulose: alkaline process
8. Regeneration of chemicals during cellulose processing
9. Technology of paper
10. Preparation of paper mass
11. Paper machine
12. Analysis of paper
13. The types and preparation of cardboards
Seminar: presentation or written seminar on a defined topic.

Organic chemistry I and II, Physical chemistry I and II, Transfer of matter and energy, Unit operation systems, Reaction engineering and catalysis
Prerequisites for attending the course: -
Development of general and specific student competencies:
Students get knowledge about natural polymer cellulose, its isolation from wood ant its application for production of paper, cardboard etc. Recycling of paper and the application of a recycled products.
Student obligations in teaching and their performance:
1. Attending the 75% of the lectures
2. Seminar work
Teaching methods:
1. Power point presentations
2. Students get teaching materials on the web page of the course
Type of examination of knowledge and examination:
Written and oral exam. Two partial exams.
Method of monitoring the quality and performance of courses: students survey
Course learning outcomes:
1. to distinguish the components of wood
2. to recommend the technology for wood processing
3. to recommend the conditions for the preparation of a paper mass
4. to estimate which additives are needed in a process of production of different paper types
5. to justify the selection of a method for the analysis of different paper and cardboard types
Program level learning outcomes:
1. solve problems scientifically, even if the problem definitions are incomplete or are formulated in an unusual way, thereby providing the spectrum of possible solutions
2. apply innovative methods in solving problems based on fundamental principles
3. solve real chemical engineering problems by scientific approach
4. independently plan their theoretical and experimental research
