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

· Future for cellulose ethers
· Visit to a viscose manufacturer
Course goals
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.
Prerequisites
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.
Examination
Assignments and a written examination
Admission rules
Each syllabus states target group and eligibility, which should be based on the prerequisites necessary to understand and process the content of the course. Syllabi and scheduled course meetings are posted on the course portal web page for the doctoral level, which is also open to the public.
Doctoral students who wish to take a course should sign up according to instructions on the course portal.
Admitted students must meet the requirements stated in the syllabus. If there are more prospective students than the teaching capacity allows, priority is given to students as follows:
- If the course is not included in the obligation stated in item 2 below, admission is primarily granted to eligible students at the department offering the course. If the course is offered jointly by several departments at Karlstad university, priority is given, as agreed, by the departments concerned. If the course is commissioned by the Faculty, all students at the Faculty belong to the prioritised group. In the case of cross-faculty courses, all students at Karlstad University belong to the prioritised group. If order of admission must be made in the prioritised group, the student who first signed up according to the requirement above, is given priority.
- If the course is part of a commitment to a national or international graduate school, network or equivalent, priority is given to their participants.
- If there is an agreement on exchange with a subject, department or faculty at another HEI, eligible students from such institutions have second priority
- Other eligible students at Karlstad University have third priority.
- Other eligible students at other HEIs have fourth priority.
The appointed course convener decides on admission of students to a doctor level course in accordance with the order of priority stated above.
Upon completion of the course, the course convener issues a course certificate with a proposed grade to the students.
Tillträdesregler
I kursplan anges målgrupp och behörighet. Behörighet ska utgå från de förkunskaper som behövs för att tillgodogöra sig kursens innehåll.
Kursplaner och planerade kurstillfällen görs tillgängliga på en webbsida: kurstorg för forskarnivå, som även görs tillgänglig externt.
Forskarstuderande som önskar följa en kurs ska anmäla detta enligt anvisning på kurstorget.
Studerande som ges tillträde ska uppfylla de behörighetskrav som anges i kursplanen. Om fler önskar följa kursen än vad undervisningskapaciteten tillåter görs prioritering enligt nedan.
- Om inte kursen ingår i ett åtagande enligt punkt 2 nedan ges tillträde i första hand till behöriga studerande vid den institution som anordnar kursen. I det fall kursen anordnas gemensamt av flera institutioner vid Karlstads universitet ges tillträde i första hand på det sätt som berörda institutioner kommit överens om. I det fall kursen är beställd av fakultet ingår alla studerande vid fakulteten i den grupp som ges tillträde i första hand. För kurser som anordnas gemensamt av fakulteterna gäller det alla studerande vid Karlstads universitet. Om prioritering behöver göras inom den grupp som ges tillträde i första hand ges den som först anmält sig enligt ovan företräde.
- Om anordnade av en kurs ingår i ett åtagande gentemot nationell eller internationell forskarskola, nätverk eller motsvarande ges dock deltagare därifrån tillträde i första hand.
- I det fall det finns överenskommelse om utbyte med ämne, institution eller fakultet vid annat lärosäte ges behöriga studerande därifrån tillträde i andra hand.
- I tredje hand ges tillträde till övriga behöriga studerande vid Karlstads universitet.
- I fjärde hand ges tillträde till övriga behöriga studerande vid andra lärosäten.
Den som institutionen utsett som kursansvarig beslutar om vilka som får delta i en kurs på forskarnivå, i enlighet med prioritetsordningen ovan.
Efter genomförd kurs och prov lämnar kursansvarig ett intyg med förslag på betyg till kursdeltagarna.
