This paper reviews the utilization of activated carbon produced from end-of-life tyre pyrolysis for gas phase adsorption in various environmental applications. The process requires a temperature of 500 degrees C to obtain high-quality carbonisate and achieve complete tyre conversion. Decreasing heating rates can increase carbonisate yields, which can be applied to gas fuel storage, VOC adsorption, and adsorption of various pollutants after activation.
This paper is a review of the use of activated carbon from end-of-life tyre (ELT) pyrolysis for gas phase adsorption in environmental applications. ELT pyrolysis is an important initial stage in the production of the adsorbent. In this case, the process should be aimed at maximizing the carbonisate yield while maintaining high product quality. A temperature of 500 degrees C is required to obtain carbonisate of high quality and achieve complete tyre conversion. Moreover, the carbonisate yield can be increased by decreasing heating rates. The carbonisate yields of 35-45 wt.% can be obtained for most types of batch reactors with proper process design. After careful physical or chemical activation, tyre derived activated carbon showed to be applicable to: (1) gas fuel storage, (2) VOC adsorption, (3) adsorption of mercury, mercuric chloride, arsenic, dioxins and furans, (4) adsorption of NOx, SO2 and CO2.
