EVALUATION OF THE PROPERTIES OF THE GAS PROCESSING BY THE THERMEL DEGREDATION OF TYRES, LIGNITE AND HIGH DENSITY POLYETHYLENE ON THE PYROLYSIS SYSTEM

This work focused on the pyrolysis gas evaluation. The criterions are: composition, production and calorific value of the pyrolysis gas from the processing of the selected shorts of organic materials and waste. The VSB - Technical University Ostrava pyrolysis equipment of the unique type has been used. Pyrolysis experiments were carried out in the temperature range from 500 degrees C to 650 degrees C of the step temperature increase of 50 degrees C for individual experiments. The residence time of materials in the retort was 45 minutes, the moisture of materials up to 20 wt. %, grain size of the material to 20 mm, the weight of material for one experimental was 60 kg/hr, pressure 101 kPa. To determine the degree of intensity of the linear dependence between the temperature ant the volume of flammable components in the gas the correlation analysis was performed.
