S）和羰基硫（COS）会导致催化剂中毒、设备腐蚀及环境污染等问题，因此煤气脱硫具有重要意义。以密度泛函理论研究方法为线索，综述了煤气干法脱硫机理研究进展。首先，讨论了H

S在不同金属氧化物、金属有机框架材料（MOFs）及活性炭材料表面的吸附机理，并分析了工业应用中常见金属氧化物表面的脱硫反应路径。其次，阐述了脱硫剂再生过程中O

在金属硫化物表面的解离及相关反应机理，进一步揭示了助剂掺杂改性影响金属氧化物脱硫再生行为的微观机理，并分析了脱硫过程中的放硫机理。在COS的催化水解/氢解转化方面，探讨了COS在催化剂表面的吸附与转化机理。最后，总结了现有研究中存在的问题，并对未来该领域的研究提出了建议。

Abstract

The presence of H

S and COS in coal gas (including gasification gas

coke oven gas and blast furnace gas) can lead to catalyst poisoning

equipment corrosion and environmental pollution

making gas desulfurization crucial. The research progress on the dry gas desulfurization mechanism based on density functional theory (DFT) was summarized. First

the adsorption mechanisms of H

S on the surfaces of various metal oxides

metal-organic framework materials (MOFs) and activated carbon materials were examined

along with an analysis of the desulfurization reaction pathways on commonly used metal oxides in industrial applications. Second

the dissociation and reaction mechanisms of O

on the surface of metal sulfides during the regeneration of desulfurizers were elucidated

further revealing the microscopic mechanisms by which dopant modification influences the desulfurization and regenerati

on behavior of metal oxides. Additionally

the sulfur release mechanism during desulfurization was analyzed. Regarding the catalytic hydrolysis and hydrogenolysis of COS

the adsorption and transformation mechanisms of COS on catalyst surfaces were explored. Finally

existing challenges in the research field were summarized

and future research directions were proposed.
