Thermochemical Processes and Pretreatment of Biomass and Waste

BIO2006
Sustainable energy systems are central to the future bioproduction. This requires knowledge and understanding of fuel's properties and thermochemical processes. The course provides knowledge about fuel characterization, storage, transport, pre-treatment and thermochemical conversion technology, and environmental consequences including the basics of techno-economic and life cycle analyzes (LCA). In addition, the subject provides insight into pretreatment processes. System design and process simulation is an important part of the course.

Sustainable energy systems are important components in the bioproduction concepts, which itself require knowledge and understandings for fuel properties and thermochemical processes. The course provides in-depth knowledge of fuel characterization, storage, transportation, pre-treatment and thermochemical conversion technologies, and environmental consequences including basics of techno-economic and life cycle analysis. Moreover, the course gives insight into such pre-treatment processes as extraction, fractionation and torrefaction and thermochemical conversion processes including pyrolysis, gasification, and combustion, with consideration of sustainable process integration for heat and material recovery. System design and process simulation is an important part of the course. Laboratory scale and industrial scale applications and methodologies are also presented in a context of equipment sizing and techno-economic assessment including the capital investment, and operating and production costs and legislative aspects.

The course will only be offered if a sufficient number of students is registered.

Elective course for the 6th semester of the BSc in Sustainable economy and bioproduction. Can be offered as a free-standing course. There are prerequisites to the courses; KJE1000 Basic Chemistry or equivalent. Higher education entrance qualification.
