Pervaporation of Methanol Water Mixtures by PERVAPTM Asymmetric Membranes.
Izák, Pavel; Kačírková, Marie
2016 - Czech
The report summarizes the results of experimental testing of pervaporative separation of methanol from methanol-water binary mixture at 35°C. For the separation were chosen the Sulzer´s PERVAPTM membranes. The concentration of methanol was 6.5 wt.% in water, and pervaporation was performed in vacuum mode. Membranes displayed separation properties suitable for industrial separation of methanol from water mixtures. Předkládaná zpráva se zabývá experimentálním testováním pervaporačního odstraňování metanolu z binární směsi metanol – voda při 35°C. K experimentům byly použity membrány PERVAPTM od firmy Sulzer a jako nástřik binární směs metanol voda v koncentraci do 6,5 hm. %. Pervaporace probíhala ve vakuovém režimu. Membrány vykazovaly separační charakteristiky vhodné pro odstraňování metanolu z vodných směsí.

Synthesis of Polymer Particles by Emulsion Polymerization.
Strašák, Tomáš
2016 - Czech
This report describes preparation of polystyrene particles with narrow size distribution by emulsion polymerization. These particles called also PS latex have size around 600-700 nm and serve as starting material for preparation of stationary phase for Ion Exchange Chromatography (IEC). Tato výzkumná zpráva popisuje přípravu polystyrenových (PS) částic s úzkou distribucí velikostí emulzní polymerací (Obr. 1). Tyto částice, nazývané také PS latex, mají velikost cca 600-700 nm a jsou výchozím substrátem pro přípravu stacionárních fází pro iontově výměnnou chromatografii (IEC).

Purification of Raw Biogas to CNG Quality by Norm 133/2010.
Izák, Pavel; Žitková, Andrea; Vejražka, Jiří; Sedláková, Zuzana; Morávková, Lenka
2016 - Czech
Membrane separation processes have recently been increasingly used in the purification of various gases. Their involvement in the processes of upgrading biogas is the logical consequence of this development. The aim of the process is removed from a biogas carbon dioxide and other undesirable substances, eg. sulfur compounds and moisture, and thus obtain a gas with a high proportion of methane (> 95 vol.%), which could be used as a substitute for natural gas. As is evident from the results of our method, the selected RO membrane conforms 133/2010 CNG norm exept the amount of water. The amount of water in the retentate (product) is solved by classical dryer. Membránové separační procesy se v poslední době stále častěji používají v čištění různých plynů. Jejich zapojení do procesů zušlechťování bioplynu je logickým důsledkem tohoto vývoje. Cílem procesu je odstranit z bioplynu oxid uhličitý a další nežádoucí látky, mj, sloučeniny síry a vlhkost a získat tak plyn s vysokým podílem metanu (> 95 obj. %), který by bylo možno použít jako náhradu zemního plynu. Jak je z výsledků patrné, naše metoda se zvolenou RO membránou odpovídá normě 133/2010 pro CNG až na množství vody. Množství vody v retentátu (produkt) je však řešeno klasickou suškou.
