This work deals with bio gas cleaning by a PSA method and modernizing of a laboratory unit. Raw bio gas contains many unwanted elements like carbon dioxide mostly which lowers its energy potential then. To extend the possibilities of usage of bio gas it is necessary to remove such elements. One of the well-known method for eliminating CO2 out of the bio gas is the method called Pressure Swing Adsorption (PSA). This work describes PSA method and compares it with other methods for cleaning the bio gas. In the following part of my work I am introducing the original laboratory PSA unit which is placed in the laboratory of UPI institution for research purposes. The modernization of the method was made by changing the manual valves for electromagnetic ones and there was also designed a new control system unit for two control modes. For manual and for automatic. The essential function is based on remote controlling the valves either by switches or by a program. The electric control panel was created for such required modes. The automated process was controlled by Arduino programming platform which was integrated into the panel. In the case of the next measurement and reading there was created a detailed description for user on how to operate the control panel and also the comments for control program of automatization.

In the first part there are described individual types of micropollutants and their occurrence in water. Further, there are described pharmaceuticals and their consumption in the world. At the end of the first part, the possibilities of removing micropollutants in drinking water treatment are approached and two water treatment plants in the Czech Republic have been selected, which already use the technology of the removal of some micropollutants. In the practical part of this diploma thesis is performed an experiment of removal of Ibuprofen from model water by adsorption on selected materials, which are Filtrasorb F100, Bayoxide E33 and GEH.

The subject of the thesis is the issue of pesticides in the environment and the possibility of their removal through activated carbon. The thesis is divided into two parts, the search part and the practical part. The research part is focused on description of activated carbon. It also deals with the distribution of pesticides and their degradation in the environment. In the practical part, a laboratory experiment was carried out to determine the effectiveness of removing pesticides and metabolites from the test water on two types of activated carbon.

This diploma thesis deals with the issue of pollution of the generated gas during gasification. It consists of two parts. The first part is theoretical, where there is a search describing the course of gasification. There is also an overview of impurities in the generated gas and a description of methods suitable for gas purification. The second part of the work is focused experimentally, where various fillings of the barrier filter are tested during gas cleaning.

This thesis deals with the isotopic composition of lead and 210 lead in recent galena from burning heaps after coal mining in the Lower Silesian basin. The studied sites were heaps in Radvanice, Markoušovice and Rybníček, where samples of galena, coal and burnt rocks were available. For the determination of the isotopic composition was used mass spectrometry with inductively coupled plasma (ICP - MS). Mass 210 Pb activity in galena was measured in a gamma - spectrometer Silar and the effect of radioactivity on galena crystal lattice was determined by the modified Williamson - Hall graph which was made from taken X-ray diffraction data. The values of isotope ratios in galena ranged for 207 Pb/206 Pb = 0,8402 to 0,8435 and for 208 Pb/206 Pb = 2,0663 to 2,0836. The average values of the coal were measured for 207 Pb/206 Pb = 0,8312 and 208 Pb/206 Pb = 2,0421. On the basis of these isotope ratios was found out that during the burning of coal and subsequent galena crystallization from hot gases there is no isotopic fractionation. Mass 210 Pb activity in galena ranged from 135 ± 9 Bq/g to 714 ± 22 Bq/g. Radioactivity of galena causes the developement of micro-deformation in the crystal structure. This micro-deformation is demonstrated by increased micro-strain in the crystal lattice. The level of this...

I examined in vitro behaviour three table varieties of grapes and Vitis rootstock Craciunel 2 during different micropropagation stages and different rhizogenezis media composition in vitro conditions. The experiment held the place in Lednice na Morave in 2018. So far have been achieved best results of 90% rooting success with DKW medium with the addition of growth regulators at this concentration of 0,2 mg.l-1 NAA + 0,2 mg.l-1 IAA + 1 mg.l-1 IBA. Multiplication protocol suitable for use in horticultural practice were optimized for Craciunel 2. Different media factors affect rooting have been determined.

This Diploma theses is dealing with the creation of general current list of reserves, production, consumption and trade of each energy raw material with a view to fossil fuel. The introduction of my work is applied to general reflection reflecting present state of fuel issue. The following chapters are talking about the aims of my work, the literature analysis and the methodology. After the introductory part there are particular chapters talking about crude oil, gas and coal. All these parts of work are dividend into the subchapters containing general introduction that describes each energy raw material. This work brings the inttegrated current data of mined fuel material organized into the synoptic tables. These tables are completed with schematic graphs. The assembled tables determine the list of the biggest international producers, consumers, shippers and importers of each strategic energy commodity. The conclusion of study belongs to the summary of determined aims of work and the outline of importance of fuels in the present-day world.

Particulate matter (PM) air pollution is one of the most important topics in the field of environmental protection, and coal strip mining is a significant source of coarse atmospheric aerosol. In order to implement appropriate regulations to improve air quality, we need to identify the major sources of pollution. PM is usually measured in a ground-based manner and its dispersion is only modelled. Therefore, the objective of this study was to measure concentrations of coarse aerosol in the atmospheric boundary layer above the area of the coal strip mine through experimental airborne measurements and to estimate pollution contribution of mining to the surroundings. Measurements were carried out from November 11 to November 26, 2012, at Vršany coal mine, Czech Republic. An electrically powered airship was used with a specially designed gondola carrying aerosol monitors DustTrak DRX and P-Trak. Temperature and relative humidity data were also recorded. Repeated flights were performed at several heights above mine edge level. PM1-10 and GPS data were recorded every second. Average airship velocity ranged from 6 to 7 ms-1 . Flight measurements were also compared to ground-based measurements of PM10 and meteorological data. Weather during our measurements was characterised by low temperatures, high relative...

The aim of this thesis is to analyze the importance of coal-fired power plants on the market of electric energy, with emphasis on aspects that fundamentally affect their production. Coal-fired power plants belongs nowadays among socially unpopular source of electricity. In recent decades intensively growing interest groups that support state intervention and regulation of the energy sector. This is essentially a massive promotion of renewable energy sources at the expense of fossil fuel plants. Analysis of individual power sources shows that despite the current restrictive measures imposed on power plants burning fossil fuels, and especially coal-fired power plants, electricity produced from coal resources is still competitive, despite some drawbacks has many positive qualities. Coal-fired power plants produce higher amounts of greenhouse gases and other pollutants than other types of power plants. On the other hand, they are able to provide a stable supply of electricity to transmission network, and thus partially offset the high volatility of electricity supply from renewable energy sources. The price of electricity from coal-fired power plants could be considered as relatively low in comparison with other energy sources. The analysis shows that in terms of practical economic policy is not economically justified to reduce the proportion of coal-fired power plants in the total production of electricity.
