Annotation -
This course is focused on a thermochemical conversion of biomass and biomass based materials and on an energetic and material utilization of its gaseous, solid and liquid products. Part of the course is thorough overview of all physicochemical properties of a biomass (elemental composition, volatile matter content, ash content and ash properties) and their impact on properties of a biomass and possibilities of its thermochemical conversion for production of heat, electricity, second generation biofuels and other chemical substances. The course is also focused on an analysis of existing restrictions on biomass usage, for energy and material purposes, connected with an availability of suitable sources (type, density per area and availability, market price) and overcoming current technological problems associated with processes of thermochemical conversion of biomass. In the course both classical (combustion, solid and fluid bed gasification, slow medium and low temperature pyrolysis) as well as new thermochemical processes (torrefaction, flash pyrolysis, multistage gasification, biochar production, supercritical water gasification) are presented. Part of the course is also an overview of all processes suitable for the production of second-generation biofuels from gaseous and liquid products of a thermochemical conversion. Strong emphasis is placed on the overall efficiency of production of electricity and other products, and on possible measures to increase it. Emphasis is also placed on the analysis of pitfalls associated with a construction and operation of a pilot or an industrial facility. Part of the course deals with an evaluation of different thermochemical processes, used for production of electricity and other useful products, in terms of efficiency and overall environmental impact.
