Characterization of Bottom Ash from Czech Waste-to-Energy Plants.
Krausová, Aneta
Our study summarizes the composition of bottom ash from two WtE plants in the Czech Republic. Bottom ash with particle size over 2 mm was characterized by combination of manual and mechanical analyses (e.g. magnetic separation, sieving, grinding, etc.). Bottom ash with particle size under 2 mm was analysed using scanning electron microscopy, to find its composition and to determine the form of comprised metals.

Comparison of Ca(OH)2 and NaHCO3 as Sorbents Suitable for Dry Flue Gas Treatment at Temperatures Below 250 °C.
Zach, Boleslav
The sorption rate of HCl on Ca(OH)2 is, in comparison with NaHCO3 (Na2CO3), an order of magnitude lower and to reach the emission limits, the flue gas treatment has to be conducted under suitable conditions. A suitable temperature for removal of acidic gases by calcium based sorbents is connected to the content of H2O in flue gas. The reaction rate is very good in the vicinity of dew point but the process conditions shouldn’t be too close to the dew point to avoid condensation. The advantages of Ca(OH)2 are better reactivity towards HF, very low water solubility of air pollution residues, and low price in comparison with NaHCO3.

Preparation of Nanocrystalline Titania Thin Films and Aerogels by using Modified Supercritical Carbon Dioxide.
Cerhová, Marie
The purity and crystallinity of prepared TiO2 thin films and aerogels were estimated by Raman spectroscopy. The crystallite size and the phase composition were determined by X-ray diffraction. Textural properties of aerogels such as the surface area and the pore-size distribution were characterized by nitrogen physisorption and helium pycnometry measurements.
