摘要

本文介绍了用热解法处理含橡胶制品,以获得热解碳,这对铸造企业的需要具有实际意义。结果表明,橡胶热解过程中的气相演化过程在50 ~ 550℃的温度范围内进行,所有检测到的物质的最大释放峰在375 ~ 500℃范围内,总释放量超过140 mg / kg原料。发现废气的浓度和温度使得利用过滤燃烧原理在自催化模式下中和它们成为可能。结果表明,固体炭质残渣(目标产物)的最佳温度为320 ~ 380℃,温度高于500℃,热解炭的质量分数从64.8%下降到31.9%,废气比例从5%提高到8%,热油收率从30.2%提高到60.1%。

Production of pyrolytic carbon from waste of rubber-containing products for use in foundry
The paper deals with the processing of rubber‑containing products by pyrolysis in order to obtain pyrolytic carbon, which is of practical interest for the needs of the foundry. It has been established that the process of gas phase evolution during rubber pyrolysis proceeds in the temperature range of 50–550 °C, the maximum release peaks for all detected substances are in the range of 375–500 °C, the total release is over 140 mg per kg of feedstock. It was found that the concentration and temperature of the exhaust gases make it possible to neutralize them in an autocatalytic mode using the principle of filtration combustion. It is shown that the optimal temperature for obtaining a solid carbonaceous residue (target product) is 320–380 °C, an increase in temperature above 500 °C leads to a decrease in the mass fraction of pyrolytic carbon from 64.8 to 31.9 %, respectively, the proportion of exhaust gases increases from 5 to 8 %, and heating oil yield from 30.2 to 60.1 %.
