FPIRC Course No. 24: Regenerated Cellulose and Cellulose Derivatives

5 sep 2012

In co-operation with: Karlstad University (KaU), Karlstad

 

Course description/Content:

The course will give the students a broad overview of the global dissolving pulp capacities and how that has been changing with time. The students will get a deep insight into the characteristics of such pulps. The cellulose structure will be discussed in detail and the students will have a good knowledge of this after the course. Process techniques for producing cellulose derivatives with focus on CMC will then follow. Process technology for viscose processes and how an enzymatic pre-treatment can improve the environmental impact will be presented. Technology for production of microcrystalline cellulose and nanocellulose will be discussed and described. The course includes lectures, a mill visit and a written examination.

 

  • Fundamentals of cellulose structures
  • Fundamental for cellulose ethers
  • Pulping processes for dissolving pulps
  • Requirements for raw material
  • CMC-chemistry, process and market
  • Viscose-chemistry, process and market
  • Other cellulose derivatives like EHEC etc
  • Future for cellulose ethers
  • Visit to a viscose manufacturer

Learning objectives: After the course, the participants should be able to ...

... discuss important cellulose ether and viscose technology aspects in an correct terminology,

... relate the results of measured parameters to different product quality aspects,

... describe the most important processes for manufacturing of regenerated cellulose and cellulose derivatives, and

.... demonstrate a deep understanding of the pros and cons of regenerated cellulose and cellulose ethers compared with other materials.

Pre-requisites: It is desirable that the participant has a good knowledge in cellulose technology, cellulose chemistry and basic chemistry equivalent to a Master level for engineering programs
