	Possibilities of using of energy by-products as raw materials for hydrothermal reaction Galvánková, Lucie ; Koplík, Jan (referee) ; Opravil, Tomáš (advisor) The aim of this master thesis is study of possibilities of processing energy by-products, especially coal fly ash and fluidized bed ash, by hydrothermal treatment. Thanks to hydrothermal conditions and proper alkali activation of ashes we can obtain zeolites. Zeolites are microporous crystalline aluminosilicates which are use in many industrial sectors as catalysts, adsorbents and very good ion exchangers. The results of hydrothermal synthesis are influenced by many variable factors. This thesis mainly focused on influence of chosen alkali activator and the concentration of the activator together with a temperature of hydrothermal process. Other factor that is studied is choice of starting materials and solution/ash ratio. Phase composition of prepared samples was characterized by XRD and scanning electron microscopy (SEM). Also cation exchange capacity of prepared samples was determined. Detailed record
	Low temperature behaviour of asphalt mixtures Štěpanovský, Vlastimil ; Stehlík, Dušan (referee) ; Hýzl, Petr (advisor) In this thesis it was paid attention to behaviour asphalt mixture of low temperature. The theoretical part deals with the technologies for reducing of mixing temperature and with their comparison. The thesis is notionally divided into two parts. The practical part is focused on the assessment of low temperature features by the test of asphalt mixture resistance against the formation of frost cracks according to ČSN EN 12697-46. Three mixtures were tested. The aim was to find if the low-temperature characteristics get worse compared to the commonly tested mixtures of the same gradation. Detailed record
	Dlouhodobá stabilita zeolitických MFI membrán Hrabánek, Pavel ; Zikánová, Arlette ; Bernauer, B. ; Fíla, V. ; Brabec, Libor ; Šolcová, Olga ; Kočiřík, Milan The aim of the study is to monitor zeolite membrane flux and separation factor as a function of total molar amount fed to the zeolite membrane surface area. The flux of permeating components (n-butane, isobutane) was reduced by factor of 1.6 for n-butane and 2.3 for isobutane. Ideal separation factor increased from 16 to 26 with increasing total molar amount of butane isomers fed to the membrane. Detailed record
