The deactivation mechanisms, regeneration methods and devices of activated carbon in applications
Activated carbons (ACs) have been widely used in many aspects of production and life, while a mass of used ACs are generated as hazardous wastes each year. Currently, waste ACs are mainly disposed of by landfill or incineration, which is not only a waste of potential resources but also a possible cause of secondary pollution to the environment. Thus, the regeneration of activated carbons seems a much better choice for waste ACs disposal. In this work, the deactivation mechanism of activated carbons during adsorption or catalysis (focusing on adsorption deactivation) was firstly interpreted then main regeneration methods, including thermal methods (thermal regeneration, microwave regeneration, etc) and non-thermal methods (chemical regeneration, electrochemical regeneration, ultrasonic regeneration, biological regeneration, etc). Subsequently, this paper introduces the regeneration devices used in some of the regeneration methods, and finally analyzes the application prospects and development trends of various regeneration methods at present and in the future.
期刊介绍:
The Journal of Cleaner Production is an international, transdisciplinary journal that addresses and discusses theoretical and practical Cleaner Production, Environmental, and Sustainability issues. It aims to help societies become more sustainable by focusing on the concept of 'Cleaner Production', which aims at preventing waste production and increasing efficiencies in energy, water, resources, and human capital use. The journal serves as a platform for corporations, governments, education institutions, regions, and societies to engage in discussions and research related to Cleaner Production, environmental, and sustainability practices.
