Evaluation of properties of pyrolysed resins
 Halasová, M. ; Chlup, Zdeněk ; Strachota, Adam ; Černý, Martin ; Dlouhý, Ivo
The presented work describes mechanical properties of materials prepared by pyrolysis of polysiloxane resins. The polymeric precursors had different chemical composition. Materials under investigation are predetermined as a matrix for high temperature resistant long fibre composites. An instrumented hardness tester was employed for materials characterisation. The Vickers hardness, Martens hardness and indentation elastic modulus were the key parameters determined from the load-indentation depth curves. Influence of the mechanical properties on the ratio of T and D was established. Indents were observed by using confocal laser microscope.

Application of a rotary kiln for the treatment of carbonaceous materials of the selective waste polymer and biomass type
 Kříž, Vlastimil ; Bičáková, Olga ; Náhunková, Jana
In the rotary kiln, samples of polypropylene and sawdust in model mixtures with bituminous-coal coke at a temperature of 900°C were pyrolyzed. The composition and features of the pyrolytic gas and solid product were observed.

Kontinuální pyrolýza uhlíkatých materiálů s modelovým zplyněním tuhého produktu
 Kříž, Vlastimil ; Káš, Václav ; Brožová, Zuzana
Samples of lignite from Jiří Mine alone and its mixtures (30%) with waste tire-rubber, Forsan (ABS) and cellulose were pyrolyzed on a rotary kiln at a temperature of 900°C. The solid product was gasified by steam and carbon dioxide.

Model laboratory unit for solid fuels and organic wastes pyrolysis
 Kříž, Vlastimil ; Buchtele, Jaroslav
Construction of a laboratory unit for solid fuels and organic wastes pyrolysis was described. The dynamics of pyrolysis was demonstrated on degassing curves and charge mass decrease curves.
