Biomass activated carbon regeneration technology is widely used for environmentaltreatment and resource recovery. Various regeneration methods are available, including thermal,chemical, microwave, electrochemical, biological, wet oxidation, supercritical fluid, and ozoneregeneration. Among these methods, thermal regeneration is the most widely used. Chemicalregeneration is a simple and cost-effective option. Microwave regeneration allows for accurate controlof regeneration parameters and quick processing of spent activated carbon. Electrochemicalregeneration can be operated at low temperatures and has good regeneration stability. Biologicalregeneration technology is a more environmentally friendly option as it can reduce the use of chemicals.Wet oxidation regeneration technology can treat activated carbon with less loss of quality and lowerenergy consumption. Supercritical fluid regeneration technology uses recyclable and non-pollutingsolvents. Ozone technology is another option for regenerating spent activated carbon at roomtemperature and pressure, which can be beneficial for the process economics. The article reviews thesetechnologies and provides an analysis of each method′s regeneration mechanism, technicalcharacteristics, and current research status.Energy Environmental Protection
