Development of low-cost contaminant sorbents from industrial waste is now an essential aspect of the circular economy since their disposal continues to threaten ecological integrity. Semicoke (SC), a by-product generated in large quantities and described as solid waste from gasification of low-rank coal (LRC), is gaining popularity in line with its reuse capacity in the energy industry but is less explored as a contaminant adsorbent despite its physical and elemental carbon properties. This paper summarizes recent information on SC, sources and production, adsorption mechanism of polluting contaminants, and summarizes regeneration methods capable of yielding sustainability for the material reuse.
利用工业废弃物开发低成本污染物吸附剂是循环经济的重要组成部分，因为这些废弃物的处置持续威胁着生态完整性。半焦（SC）是大量产生的副产品，被视为低阶煤（LRC）气化产生的固体废物，随着其在能源行业的再利用能力，它越来越受到关注，但尽管具有物理和元素碳特性，作为污染物吸附剂的研究却较少。本文总结了关于半焦的最新信息、来源与生产、污染污染物的吸附机制，并总结了能够实现材料可持续再利用的再生方法。
