中文摘要 硫化氢（H₂S）是现代社会工业生产过程中最常见的气体污染物之一，具有高毒性、腐蚀性和污染性，若处理不当会对自然环境与人类健康造成危害.生物炭因具备良好的吸附特性以及低成本和制备来源广等优点，在环境污染治理领域有着广泛的应用前景.目前生物炭吸附硫化氢技术在国内外受到越来越多的关注，但影响生物炭吸附硫化氢的因素复杂多样，需要对相关知识和研究进展进行系统地总结和归纳.从生物炭特性、吸附影响因素（生物质原料、热解温度、热解停留时间、粒径）、调控手段（包括湿度、吸附温度、吸附操作条件、改性活化）以及吸附硫化氢机制，对国内外生物炭吸附硫化氢的研究进展进行综述，通过选择合适的生物炭原材料、制备条件和优化生物炭吸附条件，从而为实现生物炭对硫化氢的高效去除提供更多的参考信息. 英文摘要 Hydrogen sulfide(H₂S) is one of the most common gas products from modern industrial processes. It is highly toxic, corrosive, and polluting, and poses harm to both the natural environment and human health if it is not properly removed. Biochar has been widely applied for the treatment of environmental pollution due to its excellent adsorption ability, low cost, and wide choice of source materials. Currently, although studies on hydrogen sulfide adsorption by biochar have attracted increasing attention, the factors involved are complex and varied, leading to a necessity to review and summarize the available knowledge and advances. To bridge the research gap, this paper presents the advances in H₂S adsorption by biochar, including properties, influencing factors(i.e., biomass feedstock, pyrolysis temperature, residence time, and particle size), control measures(i.e., humidity, adsorption temperature, operating conditions, and modification of biochar by activation), and adsorption mechanism. The work will provide further reference for the preparation and optimization of biochar adsorption conditions to realize a highly efficient removal of H₂S.
