Co3O4 Supported on Different Supports for N2O Decomposition.
Klyushina, A. ; Pacultová, K. ; Jirátová, Květa ; Obalová, L.
In this work Co3O4 catalysts supported on different kind of shaped supports (rings, quadrulobes) were prepared by incipient wetness impregnation method. As support materials commercial supports made of MgAl oxides, Al2O3 and TiO2 were used. The catalysts were characterized by AAS, XRD, Raman, FTIR, SEM, H2-TPR and nitrogen adsorption methods and tested for nitrous oxide decomposition.

Simple Equipment for Measurement of Total Pressure Tested on Poly(ethylene glycol) + Water System.
Pavlíček, Jan ; Bogdanić, Grozdana ; Wichterle, Ivan
In this work, new equipment designed for total pressure determination in mixtures where one of component is not volatile, such as polymer + solvent systems, is presented. It enables measurement of pressure above solutions in a wider concentration range. The equipment has been tested and calibrated using vapour pressure of pure water. It consist of thermostat with temperature measurement (AΣΛ, model F250), 100 ml vessel for solution with magnetic stirrer with a very strong driver, and of heated manifold for charging, degassing and for pressure measurement. Pressure is measured with use of absolute heated capacitance unit MKS Baratron (pressure range 1000 Torr = 133 kPa). Mixtures were prepared by weighing to obtain volume of 50 ml, approx.

Sorption on Clay for Transformer Oil Regeneration.
Matějková, Martina ; Kužílek, V. ; Košanová, L. ; Kaštánek, František ; Šolcová, Olga
This work is focused on finding an effective way to decontaminate such oils. For this purpose sorption was chosen as a cheap and simple decontamination technique. As sorbents two types of Czech clays were applied and their sorption efficiencies were compared with commercial sorbent usually used for treatment of an insulation oil. The real used transformer electroinsulation oil was applied in two differently sized column filled by sorbent.

Thermodynamic Limits for Dehalogenation of Producer Gas by Na2CO3, NaAlO2, CaO/CaCO3, BaO/BaCO3 and Mixed CaO-BaO/BaCO3 Sorbents.
Svoboda, Karel ; Leitner, J. ; Havlica, Jaromír ; Brynda, Jiří ; Skoblia, S. ; Hartman, Miloslav ; Pohořelý, Michael ; Hsu, H.-T.
Our study is focused on thermodynamic analyses and minimization of Gibbs energy for gas de-halogenation (removal of HCl, HF and HBr) by selected solid sorbents (Na2CO3, NaAlO2, CaO/CaCO3, BaO/BaCO3, and mixtures containing CaO-BaO/BaCO3).
