Thermal destruction of polymers: analysis of the process physicochemical parameters

This experimental study has confirmed that during thermal decomposition of polymeric waste samples at a temperature 850 °C, without oxygen access, there is 90 % drop in the mass this with release large volume gaseous products. feature should be taken into consideration engineering calculations reaction chambers, reactors, and connecting gas pipelines. The analytical was carried out by method thermodynamic analysis using universal estimation system Astra (TERRA). It been shown an increase change composition products destruction reducing mole fraction СН4 increasing proportion Н2. calorific value calculated according to Mendeleev’s empirical formula. (a pyrolysis-gas chromatography method) calculation results regarding hydrogen process temperature. As result, due lower volumetric heat combustion, total caloric content synthesis obtained significantly reduced. For experiments, laboratory installation low-temperature pyrolysis polymers external supply energy built, used as carrier. At experimental-industrial installation, method, stable combustion 24.8 kJ/m3 obtained. reliability proposed instrumental measurements shown. Promising areas further studies have determined, including optimization processes chlorine-containing polymer waste; effective use from
