This paper reports upgrading char from waste tyre pyrolysis into activated carbon via hydrochloric acid treatment. From 1.5kg tyre chips, 53.89% char was produced; the activated carbon exhibited high BET surface area (>800 m2/g) and moderate adsorption capacity, reducing sulfur content in pyrolysis oil by 36.79%. It demonstrates waste tyre valorization for circular economy.

📄 Abstract（原文）
The increased production of tyres globally and the ones discarded raises environmental concerns, stemming from the non-biodegradable nature of tyre composites and the current methods of disposal that are not effective. Only about 3 billion tyres produced annually gets reclaimed. Pyrolysis, a thermal decomposition process under inert ambience has proven to be the most viable option to treat waste tyres converting them into three-phase by-products such as char, oil and gas. This research emphasises on the low-value solid by-product (i.e char) and its further upgrade to a highly valuable adsorbent called Activated Carbon (AC), and is justified by the need for the development of new materials from waste resources. Transforming waste tyres into AC provides a unique way to manage wastes as many literature reported the production of AC from agricultural biomasses. 1.5kg of tyre chips were pyrolysed in a 10L inert atmospheric reactor core with 1.564MJ of heat at a rate of 10.20°C min-1 for 60 minutes. A percentage product yield of: 53.89% char, 28.34% oil, and 17.77% gas was derived from the pyrolysis. The char was chemically impregnated with Hydrochloric acid, producing AC with a very high BET surface area >800m2 g-1, a bulk density and porous value of 0.60g mL-1 and 0.24 respectively, upon characterisation. The AC showed a moderate adsorption capacity when 5g was used to refine the pyrolysis oil. A 36.79% drop in the sulfur content of the pyrolysis oil was observed. The results confirm that waste tyre-derived AC can be synthesised withdesirable porous and adsorption properties, aligning well with ideas of circular economy and sustainable engineering. The work details the experimental methods, AC characterisation, and potential applications in pollution control, with conclusions and recommendations for future research.
