Biomass gasification with carbon dioxide
Klíma, David ; Milčák, Pavel (referee) ; Baláš, Marek (advisor)
This master’s thesis deals with the process of biomass gasification using mixture of CO and O2 as gasification agent. First part describes the gasification process itself, used devices, gasification medium and its influence on the generated gas. Following section covers the experimental part of the work, which is focused on change properties of the generated gas using different ratios of CO2, O2, H2O and air in the gasification mixture. This part also includes processing and evaluation of the results.
Atmosferic gasification of biomass by the addition of oxygen and steam
Vypušťáková, Veronika ; Milčák, Pavel (referee) ; Baláš, Marek (advisor)
The topic of master´s thesis is atmosferic gasification of biomass by the addition of oxygen and steam. The theoretical part is devoted to the description of biomass, process of gasification, kinds of gasification reactor and product gas. Further experiments are devised depending on the gasification medium and output temperature. In this case, the key aspect is the steam addition control. In the practical part, these experiments are performed in a fluidized bed reactor. Resulting values from samples of gas and tar are subsequently processed and evaluated.
Biomass gasification with oxygen
Dubinová, Petra ; Lisý, Martin (referee) ; Baláš, Marek (advisor)
Biomass gasification using air with addition of oxygen can be the right way to increase the quality of the syngas produced. This thesis aims to characterize the gasification process using oxygen-enriched air and verify its effect on the gas. The theoretical part deals with description of the technology with an emphasis on various gasifying agents and different possibilities of increasing gas quality. The practical part contains the results of measurements on the atmospheric fluidized bed reactor and their evaluation. The experiment was performed with various oxygen enrichment taking into account the capabilities of the equipment used.
The use of flue gas for the biomass gasification
Švácha, Filip ; Milčák, Pavel (referee) ; Baláš, Marek (advisor)
The aim of this thesis is to describe the process of biomass gasification using gas simulating the composition of flue gas – a mixture of oxygen, carbon dioxide and water vapor. In the research part of the thesis the issue of gasification with the focus on fluidized bed gasification and the effect of the gasification medium used on the gasification process is discussed. In the practical part the thesis deals with the design, realization and evaluation of the experiment on a real device. The aim of the experiment is to determine the effect of the exact composition of the mixture of these three media on the gasification process and on the quality of the gas generated. The aim is to find the optimum composition for obtaining gas with the highest possible lower heating value, which contains as little tar as possible. At the end of the work, the results from the experiment are presented and described.
