Abstract

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.

活性炭在应用中的失活机理、再生方法和装置

活性炭（AC）已被广泛应用于生产和生活的诸多方面，而每年都会产生大量的废活性炭作为危险废物。目前，废活性炭的处理方式主要是填埋或焚烧，这不仅浪费了潜在的资源，还可能对环境造成二次污染。因此，活性炭再生似乎是处理废活性炭的更好选择。本文首先解释了活性炭在吸附或催化过程中的失活机理（重点是吸附失活），然后介绍了主要的再生方法，包括热法（热再生、微波再生等）和非热法（化学再生、电化学再生、超声波再生、生物再生等）。随后，本文介绍了部分再生方法中使用的再生装置，最后分析了各种再生方法在当前和未来的应用前景和发展趋势。

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.
