Fast pyrolysis reactors
Fencl, Jonáš ; Lachman, Jakub (referee) ; Elbl, Patrik (advisor)
The aim of the bachelor thesis is a description of a fast pyrolysis process, its products and technologies based on the principle of fast pyrolysis using biomass as a fuel. In the first part of the thesis biomass and its energetical usage is described. The second part focuses on a charachteristics and history of pyrolysis. The third part describes fast pyrolysis process, convertion to bio-oil and important process parameters to obtain maximum liquid yield. Furthermore, single components obtained from the fast pyrolysis process and their usage is described. The fourth part describes types of fast pyrolysis reactors, their advantages and disadvantages. At last, the largest pyrolysis units operating in practice are described.

Torrefaction of biomass for energy use
Sverkunová, Kristina ; Ivanova, Tatiana (advisor) ; Krepl, Vladimír (referee)
The Bachelor thesis is focused on torefaction of biomass for an energy use. It describes the technology including basic reactors, compares wet and dry torefaction and used materials that can be used for an agricultural waste. In the thesis I compared advantages and disadvantages of torefaction considering all hydrophobic, grindability and emission of greenhouse gasses.
Second and the important part of the thesis is the recent commercial use of biomass. Data are mainly taken from the SECTOR study, which was made in March 2016. So it can be considered as a recent data. This part is also concentrated on possibilities of faster development of this technology thanks to the commercial use. It is also explaining the importance of norms, which have not been regulated yet.
The conclusion refers to the main assets of this technology, when the usage of fossil fuels and its more ecological substitutes are discussed. I mentioned the problem of a carbon footprint is connected to a possible raise of wood materials import, that will be unavoidable in order to satisfy expected demand for year 2020.

Possibilities of utilization grass material.
ŠVARC, Miroslav
At work, there are introduction primary kinds of technology of processing grass material. There are description composting waste, incineration, flash pyrolysis and anaerobic digestion too. At the close, there are introduction possibilities of utilization of biogas.
