High pressure sorption of CO2 and CH4 on coal from Upper Silesian Basin
Přibyl, Oldřich
2013 - Czech
High pressure adsorption isotherms of CO2 and CH4 were measured on three coal samples at 45 C temperature. The ratio of CO2:CH4 was determined to be around 1.75. The influence of coal maceral composition on gas adsorption was determined. Na třech vzorcích uhlí při 45°C byly změřeny vysokotlaké adsorpční izotermy CO2 a CH4. Byly stanoveny vzájemné sorpční poměry CO2 : CH4 ve výši kolem 1,75. Byl stanoven vliv maceráloveho složení na adsorpci výše uvedených plynů.

The ash quality monitoring of biomass combustion
Tlustoš, P.; Ochecová, P.; Száková, J.; Perná, Ivana; Hanzlíček, Tomáš; Habart, J.; Straka, Pavel
2012 - Czech
The aim of methodology was, on the basis of results of analyzes of ash from more than 40 sources in the Czech Republic, these ash categorize by feedstock and identify suitable ash for use on agricultural land. It could lead to a significant shift to reduce the cost of incinerators, to the entry of new businesses on the market and to easier fulfilling of republican obligations in the share of energy production from renewable sources. Another advantage of finding employment for these materials, from an environmental view, is the reduction of landfilling and support for recycling of nutrients. The methodology presented the process for the selection of suitable ash for agricultural purposes and the reader should be able to determine the applicability of the material. Cílem metodiky bylo na základě zjištěných výsledků analýz popelů z více než 40 zdrojů v České republice tyto popele kategorizovat dle vstupní suroviny a vytipovat vhodné popele pro použití na zemědělské půdě, což by znamenalo významný posun ke snižování nákladů spaloven, vstup nových provozoven na trh a snadnější dodržování republikových závazků při naplňování podílu produkce energie z obnovitelných zdrojů. Další výhodou nalezení uplatnění pro tyto materiály, z environmentálního hlediska je omezení skládkování a podpora recyklace živin. Metodika v ucelené podobě předkládá postup při výběru vhodných popelů pro zemědělské účely, aby byl čtenář schopen určit použitelnost daného materiálu.

Sterilization Decomposition Evaluation of Radiolucent Composite Materials for Use in Medicine
Sochor, M.; Balík, Karel; Suchý, Tomáš; Sedláček, R.; Sucharda, Zbyněk; Beneš, J.; Prokop, J.
2011 - English
This study evaluates the resistance against multiple sterilization processes of radiolucent composite materials for use in medicine as an intraoperative imaging device material. The composite materials under investigation here are composed of carbon fibers, polyphenylene sulfide and polyetheretherketone matrix. The influence of multiple sterilization processes on changes in their mechanical and structural properties are determined. The radiolucency of the proposed composites is verified.
