CHEM-E1115 - Biomass Fractionation I D, Lecture, 7.1.2025-14.2.2025

Please note! Course description is confirmed for two academic years, which means that in general, e.g. Learning outcomes, assessment methods and key content stays unchanged. However, via course syllabus, it is possible to specify or change the course execution in each realization of the course, such as how the contact sessions are organized, assessment methods weighted or materials used.

LEARNING OUTCOMES

After the course, the students are able to,

describe chemical pulping processes with emphasis on kraft pulping, 
describe in detail the most important pretreatment processes for the successful fractionation of lignocellulose biomass,
illustrate the transport phenomena underlying the pre-treatment processes,
explain the phenomena taking place during different biomass refining process steps based on the knowledge of the chemical reactions and the principles of reaction kinetics,
discuss the chemistry and technology of existing and novel fractionation processes and, based on this knowledge, formulate the principles of a forest biorefinery.

CONTENT, ASSESSMENT AND WORKLOAD

Content

  • valid for whole curriculum period:

    The course is focused on biomass fractionation via chemical processes. The most important technical pre-treatment methods will be presented and then the chemistry and technology of the most important fractionation methods is covered. The main emphasis is on kraft pulping, but also other fractionation methods are covered (e.g. acid sulfite and the most relevant organosolv fractionation methods). An integral part of this course are exercises, covering selected examples (e.g., heat transfer, reaction kinetics, diffusion in lignocellulose matrix).

Assessment Methods and Criteria

  • valid for whole curriculum period:

    Mastering the content of the course with respect to the learning objectives.

Workload

  • valid for whole curriculum period:

    Lectures, exercises and independent studying. In total 135 h.

    Exam.
