Abstract
Activated carbon regeneration refers to the process of physically or chemically treating spent activated carbon after it has reached adsorption saturation, in order to restore most of its adsorption performance and reuse it. With the increasing environmental protection requirements and the deepening of the circular economy concept, regeneration technology has become a key focus of industry development.
1. Why should we attach importance to regeneration?
Significant economic benefits: The cost of regeneration is typically much lower than purchasing new carbon. Technical case studies show that advanced regeneration technology can reduce the cost per ton of regeneration by approximately 200 yuan.
Environmental protection is essential: directly discarding waste activated carbon may cause secondary pollution or pose challenges in hazardous waste disposal. Standardized regeneration is the optimal path to achieve resource recycling and reduce environmental burden.
Policy-driven: Under the "dual carbon" goal, resource recycling is a clear direction. Data shows that the proportion of recycled activated carbon has increased from 15% in 2020, and is expected to reach 22% by 2025, with a compound annual growth rate of up to 18.5%.
II. Technical Breakthrough Points and Efficiency Indicators
Traditional regeneration technologies face challenges such as high energy consumption, low regeneration rates, and potential for secondary pollution. Current technological innovations are revolving around addressing these issues:
Enhancing regeneration rate: a key indicator to measure the recovery degree of adsorption performance of regenerated activated carbon. Advanced technologies in the industry have been able to increase the average regeneration rate from 85% to over 92%.
Reduce energy consumption: By optimizing the furnace structure, adopting new insulation materials, upgrading the automatic control system, etc., the energy consumption per unit of regeneration can be reduced from 110 kg of standard coal per ton to 92 kg of standard coal per ton.
Prevent secondary pollution: Advanced regeneration systems can effectively treat exhaust gas, ensuring emissions meet standards (such as exhaust VOCs concentration ≤10mg/m³).
