Thermochemical biomass conversion is based on decomposition at high temperatures (and sometimes high pressures), and subsequent chemical conversion whether or not in the presence of catalytic materials. Traditional processes are combustion, gasification and carbonization. The corresponding products are heat, combustible gases and charcoal respectively. This course is meant to explain the principles of both traditional and new thermo-chemical conversion processes and to discuss the various process routes in relation to the products desired. Biomass resources and properties are considered with special attention for environmental impact and aspects of sustainability. Although biological conversion routes are not a topic in this course, the relation between biological and thermochemical process routes will be clarified. In modern biorefinery concepts, both process types are often combined.
COURSE JUSTIFICATION/RATIONALE
The course focuses on Bio-Energy and in particular on the exploitation of biomass and biomass waste for energy recovery. The course encompasses thermochemical energy processes (combustion, gasification, pyrolysis, reforming), mechanical and chemical processes (oil extraction and trans-esterification), finally biochemical processes (fermentation and anaerobic digestion). Emphasis is given to thermochemical processes.
The course provides chemical engineering tools applied to the analysis of energy conversion processes involving biomass. The course provides also the fundamentals of ASPEN PLUS- a software package designed for process modeling and simulation that is extensively utilized in chemical and energy industrial sectors. The student at the end of the course will be capable to design a bio-energy thermo-chemical conversion process.
LEARNING OBJECTIVES
By the end of this course, the student should be able to:
