Název v původním jazyce

Microwave-assisted pyrolysis of waste for xylene adsorbent preparation

Popis výsledku v původním jazyce

Disposing of waste materials, particularly polymers (e.g. scrap tyres), biomass (e.g. corn cob, waste from tomato production) and animal by-products (e.g. waste animal bones from slaughterhouse), has become an urgent environmental issue. Microwave pyrolysis and/or co-pyrolysis is a promising way to convert these waste materials or mixture of these waste into valuable carbon-based adsorbents. Compared to conventional pyrolysis, microwave-assisted processes offer greater controllability and efficiency (e.g. lower retention time), as well as being more cost-effective. Carbons produced by microwave pyrolysis, such as pyrolytic carbon black and chemically activated pyrolytic carbon black, exhibit excellent adsorption properties for polar and non-polar volatile organic compounds (VOCs) in gaseous streams. The adsorption performance of these materials is strongly influenced by the type of feedstock and the preparation parameters (e.g. microwave power, residence time, and the presence of chemical activators).This study investigates the adsorption behaviour of carbons derived from various waste sources, both with/without chemical activation. A comprehensive characterisation of the textural, chemical and surface properties of the adsorbents is conducted. Furthermore, adsorption experiments are performed using xylene as a model VOC in the gas phase. The results provide insights into the key factors that govern adsorption capacity and highlight the potential of carbons derived from microwave pyrolysis as cost-efficient adsorbents for environmental remediation applications.
