Content and learning outcomes

Course contents

The course consists of lectures, a literature seminar and eventually laboratory work. The examination is done in combination with a written examination and a written and an oral presentations of the seminar task.

Lectures:
Chemical reactions during, mechanical fiber release, chemical reactions during chemical fiber release, chemical reactions during biomass pretreatments, chemical reaction during acid hydrolysis, , generation and storage of process chemicals, the biorefinery and the environment, and its chemical cycle, Platform chemicals and Material concepts.

Intended learning outcomes

After completing the course, the student should be able to:

  • Demonstrate understanding of mechanisms involved in pulping and biorefining techniques 
  • Understand and predict how the hierarchic structure of plant fibers are affected during biorefinery processes 
  • Understand the principles of characterization techniques and how they apply to generated substrates in biorefining
  • Demonstrate understanding of chemical and physical aspects of processes for production of cellulose- and lignin- derivatives, platform chemicals and other chemicals produced from plant biomass with consideration taken to a sustainable society
  • Demonstrate literature search capabilities, report writing and oral presentation capabilities

Literature and preparations

Specific prerequisites

  • At least 150 credits from grades 1, 2 and 3 of which at least 110 credits from years 1 and 2, and bachelor's work must be completed, within a programme that includes: 50 university credits (hp) in chemistry or chemical engineering, 20 university credits (hp) in mathematics and in computer science or corresponding.
  • Completion of Biofiber Chemistry Course (KF2460) or similar Fiber Chemistry related courses.

Recommended prerequisites

KF2460 Biofibre Chemistry, or BB2420 Glycobiology and Carbohydrate Technology, or corresponding knowledge. The older course wood chemistry and wood biotechnology is also a good background.
