Dissolution of silicates for carbon dioxide mineral storage
Křečková, Magdaléna ; Havlica, Jaromír (referee) ; Ptáček, Petr (advisor)
The degradability of wollastonite, montmorillonite and talc in an aqueous solution of acetic acid at different temperatures is main object of this study. Mineral carbonation, i.e. the reaction of calcium and magnesium presented in these three silicates, is a novel and promising approach to carbon dioxide capture and long-term storage. The kinetic of wollastonite, montmorillonite and talc dissolution is studied due to assessment of their efficiency for CCS technologies. The dissolution kinetic is discovered with using measured time dependence of Ca2+ and Mg2+ leached ions concentration.

Possibilities of connecting the Asterisk softswitch to the 4th generation PBX
Halamík, Zdeněk ; Krajsa, Ondřej (referee) ; Šilhavý, Pavel (advisor)
This master’s thesis dissertate the possibilities of the linkage between Asterisk softswitch and the 4th generation private branch exchange. This should create a new generation’s network, so-called NGN, by the convergence of existing telecommunication networks with an IP computer network. This master’s thesis is divided into several chapters. In introduction is described the evolution of the private branch exchanges as well as the principles of the voice digitizing, codecs and signaling commonly used in both TDM and VoIP networks. The main aim of this project is the configuration of Asterisk software exchange for connection with PBX Alcatel 4400 as well as public phone network PSTN. Another goal of this master’s thesis was the configuration of Alcatel PBX and diagnostics of CCS and CAS signaling on E1 interface. In conclusion there are summarized advantages of NGN networks and their utilization in the future.

Balance sheet calculations for CCS technologies
Kotráš, Pavel ; Lisý, Martin (referee) ; Baláš, Marek (advisor)
This thesis deals with CCS technology. In the first part, the main greenhouse gas carbon dioxide is described. The second part focuses on the description of the CCS technology and possible methods of capturing carbon dioxide and other gases. The third part is devoted to the calculations for the application of CCS technology, specifically the high-temperature carbonate loop, to a real lignite-fired power plant. At the end of the thesis is the overall balance of the power plant, which includes a comparison with and without the use of CCS technology.

Methods and technologies for carbon dioxide capture in industrial plants
Rek, David ; Máša, Vítězslav (referee) ; Sukačová, Kateřina (advisor)
The rising level of carbon dioxide in the atmosphere has negative effects on life on our planet. Humanity is now dealing with the issue through multinational organizations which attempt to motivate the current industry to develop innovative solutions to increase the energy-efficiency while lowering the amount of produced emissions. The most affected are energy-intensive sectors of the industry, such as the ceramics industry. This diploma thesis is based on a thorough research conducted on scientific literature, mainly scientific articles. The theoretical part is to familiarize one with the issue of rising levels of carbon dioxide. Next, methods to capture, store and use the gas are presented. Furthermore, the thesis focuses on one such method – microalgal bioreactors. The practical past weighs the usability of microalgal bioreactors for the purpose of carbon dioxide emissions capture in a production company LASSELSBERGER, s.r.o. belonging to the ceramic industry. Tubular bioreactor with a volume of 2000 m3 would process 3,75 % of CO2 produced by the core production machine – spray drier, during this process 367,92 tons of microalgal biomass would be produced annually.

Methods and prospects of CCS from emissions of energy sources in ČR
Pulkrábek, Jan ; Přibil, Rudolf (advisor) ; Hovorka, Jan (referee)
With increasing frequency of problems caused by global climate change, the scientific community trying to find possible solutions to reduce greenhouse gas emissions into the atmosphere. One of the possible solutions of this problem is considered the system of separation, transportation and long-term storage of C02, called CCS - Carbon Capture and Storage. This work is a literature review issues of CCS in order to determine the possible use of CCS in the Czech republic. There is a basic system description of CCS, the possible environmental risks associated with it, and finall summarize of the prospects of deployment CCS technology in Czech republic.

Design of a spray column for CO2 capture
Veselý, Filip ; Malý, Milan (referee) ; Cejpek, Ondřej (advisor)
This work deals with methods of CO2 separation from flue gases in energy industry and industrial processes in order to reduce CO2 concentration in the atmosphere. Bachelor thesis discusses the post-combustion CO2 capture using spray columns. After literature review of separation processes and experiments conducted before, advantages and disadvantages of separation processes are discussed. The following part of bachelor thesis is dedicated to the analysis of spray column components. At the end of this chapter the suitable components are chosen and designed. The main outcome of the work is a conceptual design of a spray column. Spray column is designed for research purposes at Faculty of Mechanical Engineering in spray labs. In the design procedure main aim was devoted to suitable spray columns design for optical experiments. During the spray column design the space requirements of the laboratory and economic of the design need to be accounted.
