Biogas composition
Čekanová, Adéla ; Pěček, Jan (referee) ; Beňo, Zdeněk (advisor)
Content of the submitted bachelor thesis is a description of biogas chemical composition with following analysis of each unit, especially majority units, with use of different gas analysis methods. Main emphasis is set on biogas units which have undesirable effects while using it as energy source and on possibilities of removing them using set technologies. In larger scale the bachelor thesis is concerned with teoretical possibilities of removing sulphur from biogas and following methods used in work experience.

Fuel-energy Properties of Stabilized Sewage Sludge
Pohořelý, Michael ; Durda, Tomáš ; Moško, Jaroslav ; Šyc, Michal ; Kameníková, Petra ; Zach, Boleslav ; Svoboda, Karel ; Hartman, Miloslav ; Beňo, Z. ; Parschová, H. ; Houdková, L. ; Punčochář, Miroslav
The paper summarizes significant fuel-energy and physico-chemical properties of stabilized sewage sludge. Sewage sludge as a fuel is characterized by high proportions of water content, volatile matter content, ash content and a considerable amount of reactive, organic nitrogen (2-5 wt. % of dry matter). In addition to oxygen; silicon, phosphorus, aluminum, iron and calcium are the most abundant elements in the ash from the sludge. The lower calorific value of dry, anaerobically stabilized sewage sludge is 9-12 MJ kg-1 and it corresponds to a low calorific value of lower-class subbituminous coal or lignite.

Gas Cleaning for High Temperature Fuel Cells with Solid Electrolyte
Pohořelý, Michael ; Svoboda, Karel ; Skoblia, Sergej ; Jeremiáš, Michal ; Kameníková, Petra ; Šyc, Michal ; Parschová, H. ; Cabáková, G. ; Šustr, V. ; Durda, Tomáš ; Beňo, Z. ; Punčochář, Miroslav
The aim of this paper is to introduce readers (listeners) to the basics of gasification process, high temperature fuel cells with solid electrolyte and particularly with the problems of high-temperature gas cleaning system of the producer gas from gasification of woody and agricultural biomass and/or alternative fuels (e.g. refuse derived fuel) to the level needed for its use in combined production of heat and electric power in high-temperature fuel cells with solid electrolyte (SOFC).
