Contamination of the environment by crude oil originated fuels, its detection, remediation and prevention
Heclová, Naděžda ; Adamec, Vladimír (referee) ; Čáslavský, Josef (advisor)
This bachelor thesis focuses on crude oil-based fuels and water and soil contaminations caused by these substances. Crude oil and the process of producing fuels out of crude oil as well as the fuels themselves (car petrol and diesel oil) are characterized in the work. The thesis also describes the methods used for their detection in the environment, the decontamination processes and the ways of petroleum products leaks prevention.
Preparation of CoMo/MgO Catalysts for Hydrodesulfurization
Gulková, Daniela ; Kaluža, Luděk ; Zdražil, Miroslav ; Vít, Zdeněk
The aim of the present work was to elucidate the possibility of deposition of molybdenyland cobalt- acetylacetonates on the high surface area MgO by impregnation from solutions of these compounds in methanol. Furthermore, non-aqueous solutions of MoO3 and CoCO3, (NH4)6Mo7O24 and Co(NO3)2, MoO2(C5H7O2)2 and Co(C5H7O2)2 with chelating agent nitrilotriacetic acid (NTA) were studied for CoMo deposition in one impregnation step.

Fuel prices and their effect on economic activities of a selected company
Novotný, Tomáš ; Müller, Štěpán (advisor) ; Taušer, Josef (referee)
The bachelor thesis deals with the issue of fuel prices and their effect on economic activities of a transport company. The thesis is divided into three chapters. Because the most of present fuels are made from oil, the first chapter is devoted to basic information on oil. The chapter also describes what main components of fuel prices are. The second chapter clarifies the impact of fuel prices changes on economic activities of the public transport company. The third chapter focuses on ways how the company can optimise its economic activities in order to reduce or eliminate impacts of fuel prices changes.
Comparison of production and consumption of methyl ester of rapeseed oil in Central Europe.
Voborníková, Zuzana ; Sedláček, Jiří (advisor) ; Toužimský, Libor (referee)
In my work I deal with biofuels, especially with methyl ester of rapeseed oil (called RME). Why should be biofuels used as a substitute for oil. What materials are suitable for biofuel production. What are suitable procedures for their production. Comparison of production and consumption in Central Europe. Estimated development of future need for biofuels. The real contribution of RME to improving the environment.
Location, evalution and analysis of the cost for production of a pasturage in chosen establishment with higher steep lands.
KÜMMEL, Miloš
The graduated thesis is described the characteristic of a permanent grass vegetations, analysis of the scale of production a pasturage in chosen establishment and identification with a technological line for harvest and conservation pasturage. Next describe size of a store, land steep a traffic distance. This thesis describes measuring procedure in order to location of engineering characteristics, consumption of fuels and financial evaluation of all operation in the end.
