Thermochemical Conversion: Gasification

This lecture covers the thermochemical conversion of biomass, focusing on gasification as a key process. It discusses biomass conversion routes, production potential in Switzerland, different gasification technologies, gas composition modeling, efficiency of gasifiers, gas cleaning methods, and the gasification system design. The lecture emphasizes the principles of gasification versus pyrolysis, the types of gasifiers, gas composition as a function of the gasifier type, and the importance of gas cleaning. It concludes by highlighting the production of CO and H2, the role of the gasifying agent, heat generation methods, critical design considerations, ash separation, gas cleaning, and heat recovery.
