Determination of organic compounds in the tar
Magdechová, Andrea ; Čáslavský, Josef (referee) ; Vávrová, Milada (advisor)
The diploma thesis deals with determination of organic compounds in the tar. It is focussed on polycyclic aromatic hydrocarbons, BTEX and n-alkanes. The tar samples were collected by Faculty of Mechanical Engineering BUT Brno during two days and under diferent conditions of biomass gasification. The samples were filtrated and refined using column chromatography on silicagel sorbent. Gas chromatography with mass detection was chosen to determine polycyclic aromatic hydrocarbons and gas chromatography with flame ionisation detection was chosen to determine BTEX and n-alkanes.

Biomass gasification
Drga, Miroslav ; Baláš, Marek (referee) ; Škvařil, Jan (advisor)
Bachelor thesis contains a brief introduction of biomass, its composition, source and thermal characteristics. An analysis of gasification technology and gasification research facility. Then there are products of the gasification and combustion technology, and comparison of gasification.

Gasification Technologies in the Czech Republic and Abroad
Kunert, Šimon ; Baláš, Marek (referee) ; Lisý, Martin (advisor)
This bachelor's thesis deals with gasification technologies in the Czech Republic and abroad. The first part describes brief history of gasification, characteristics of the process, the most important types of equipment intended for this purpose, what are their properties and possibilities of use in practise. A separate part is dedicated to biomass gasification. The second part is dedicated to companies and institution that have dealt with this technology. There is a place of business in which the company operates, and a brief description of their equipment with specific use in practice.

Determination of organic substances in tar formed after biomass combustion and gasification
Hájek, Radek ; Mravcová, Ludmila (referee) ; Vávrová, Milada (advisor)
Biomass pyrolysis and gasification techniques count among basic technological procedures for its use as a source of energy. As a side-effect, production of tar can be considered. Tar is a complex mixture of various organic compounds and affects negatively both the environment and the facilities where biomass is processed. Within the scope of this master thesis the analysis of tar samples from different materials was performed. As an appropriate analytical method the gas chromatography combined with flame ionization detection (GC-FID) and time-of-flight mass spectrometry (GC-TOF-MS) was chosen. The concentrations of volatile organic compounds known as BTEX, polycyclic aromatic hydrocarbons (PAH) and phenolic compounds were assessed.
