Comparison of the chemical composition of char from waste car tires to the coke breeze used in the iron ore sintering process

[摘要] The increasing automotive development generates large amount of waste car tires, which cannot be landfilled and the reuse level of raw materials used in vehicles production must achieve at least 95 %. The calorific value of waste tires is very high and they can be considered as energy carries, for example in the form of char generated during pyrolysis process. The article presents the results of chemical analysis of char samples and parameters which are crucial from the environment and iron ore sintering process point of view. The results show, that char samples with high carbon content, low sulfur, zinc and pyrolysis oil content can be applied in the iron ore sintering process.
