Plynová chromatografie v bioplynových technologiích se zaměřením na analýzu neuhlovodíkových plynů
Sapoušek, Adam
This bachelor thesis deals with the analysis of non-hydrocarbon gases, which are called permanent gases. They are produced during biogas production in biogas stations by gas chromatography. At the beginning of the thesis is research about currently used methods for determination of permanent gases in biogas technoligies. The research is also focused on overview of chromatography function and its instrumentation, detectors and instruments. In the next part there is methodical desctription of the gas chromatography operator, on which were analyzed series of biogas samples and their evaluation. From the results I will draw conclusions.
The possibilities to combine biogas production and biowaste hydrothermal carbonization
Usťak, Sergej ; Honzík, Roman ; Muňoz, jakub
The objective of the methodology is to provide to farmers, agricultural consultants, owners and operators of biogas plants, to biowaste producers and processors, to experts in the field of soil reclamation and melioration, to investors and other interested parties on the concerned issues, the basic information about the potential at the combination of biogas production and biowaste hydrothermal carbonization. These options are evaluated on the basis of processing at accumulated energy intensity for the above combined processes and its comparison with conservative biogas production using the example biogas plant with installed electrical capacity of 800 kW. Part of the methodology is guided to evaluate the potential use of thermo- pressure hydrolysis unit as a device for digestate hydrothermal carbonization and other wastes in order to improve their performance, particularly in terms of employment in agriculture as highquality substrates for soil fertilization and for the purpose of soil carbon sequestration.

Stanovení chemických a toxikologických vlastností prachových částic a výzkum jejich vzniku: Biomasa a procesy jejího využití z hlediska emisí částic a dalších polutantů - 1
EGÚ Praha Engineering, a.s., Praha ; Fara, Milan
Projekt je zaměřen na Biopaliva jakožto pohonné hmoty, jejichž používání je legislativně upraveno. Problematika biopaliv zahrnuje požadavky na pohonné hmoty pro motorová vozidla a zavedení biopaliv až k podrobnějšímu popisu jednotlivých výrobních technologií (výroba bionafty, bioethanolu, methyl- a ethyl-terc-butyl-etherů, výroba syntetických paliv z biomasy, výroba syntézního plynu, výroba biomethanolu a bio-dimethyletheru. Je popsána výroba bioplynu a využití komunálního odpadu k jeho výrobě. Zvláštní kapitola je věnována emisím z lesních požárů. Je uveden přehled o množství spálené biomasy ve velkých zdrojích vedených v registru REZZO 1, a to pro zavedené kategorie biomasy v členění podle krajů a okresů. Projekt je zasazen do legislativního kontextu.
The comparison of selected plant cultures as different energy resources
PAVELOVÁ, Lenka
This bachelor thesis was made by form of literature retrieval, eventually added of any tables and graphic design of acquired data and own commentary (discussion) to the literature details. The aim of the work will assess the suitability of selected crops for cultivation in energy use with respekt to growing thein technology and assess the suitability of biomass for different wals of processing and energy recovery. A brief outline of the economic, ecological and economic importace of the topic. In the second chapter of literature review are provided information about renewable energy sources, what the renewable energy resources are, their significance and use. The chapter also discusses the importance and use of biomass as energy source, characteristic of various types of biomass and finally is mentioned the future of biomass. In the third chapter ?Selection and cultivation of plants for energy recovery? summarizes the information about selected woody and non-woody crops characteristic for energy use. It is these crops - grains, maize, fast growing woody plants, monocultures of grass, clover mixture, monoculture legumes, herbs, permanent grassland: the productive and out of productive importance. For individual crops are processed: general characteristics of plants, botanical classification, requirements for habitat, agricultural engineering, harvesting and post harvest treatment. Below are listed possibilities of production and outlined the use of crops for energy purposes. The fourth chapter deals with the ways of using biomass for energy purposes. By using wood, straw and energy crops for direct combustion of biomass to produce biogas and other forms of exploitation. Finally in the fifth chapter is a summary of key findings and recommendations resulting from studying issue, extended tables and graphical processing.
