Abstract

The dye and textile industry commonly employs activated carbon adsorption technology due to its cost-effectiveness and high efficiency. However, disposing of waste-activated carbon has a significant environmental and human health impact, and it’s a huge economic waste. This study investigates the kinetic and isothermal adsorption characteristics of Acid Red G dye adsorption by Powdered Activated Carbon derived from coconut shells. To effectively reuse activated carbon and maximise resource conservation, regeneration experiments were carried out using Supercritical Water at 24 MPa and 400 ℃ for 30 min. The experimental results demonstrated that, in comparison with thermal regeneration, supercritical water possesses the benefits of environmental protection, economic efficiency and extensive applicability. This is of considerable importance to the field of research concerning the regeneration of activated carbon.

饱和酸红G的生物基活性炭超临界水再生研究

活性炭吸附技术具有成本效益高、效率高等优点，在染料和纺织工业中得到广泛应用。然而，垃圾活性炭的处理对环境和人体健康有重大影响，是一种巨大的经济浪费。研究了椰壳粉状活性炭吸附酸性红G染料的动力学和等温吸附特性。为了有效地回收活性炭，最大限度地节约资源，采用超临界水在24 MPa、400℃条件下进行了30 min的再生实验。实验结果表明，与热再生相比，超临界水具有环保、经济和广泛适用性的优点。这对活性炭再生的研究具有重要意义。

期刊介绍： Carbon Resources Conversion (CRC) publishes fundamental studies and industrial developments regarding relevant technologies aiming for the clean, efficient, value-added, and low-carbon utilization of carbon-containing resources as fuel for energy and as feedstock for materials or chemicals from, for example, fossil fuels, biomass, syngas, CO2, hydrocarbons, and organic wastes via physical, thermal, chemical, biological, and other technical methods. CRC also publishes scientific and engineering studies on resource characterization and pretreatment, carbon material innovation and production, clean technologies related to carbon resource conversion and utilization, and various process-supporting technologies, including on-line or off-line measurement and monitoring, modeling, simulations focused on safe and efficient process operation and control, and process and equipment optimization.
