Abstract:
To achieve the resource utilisation of high-value CO in yellow phosphorus off-gas, the key lies in the deep removal of sulphide impurities such as H₂S, COS and CS₂ (requiring post-purification concentrations to below 0.1 mg/m³). This paper systematically reviews the research progress in deep desulphurisation technologies for yellow phosphorus off-gas, focusing on innovative industrial-scale technologies in key areas such as adsorbent materials, catalytic systems and absorbents. It provides a detailed analysis of the mechanisms, process parameters and performance indicators of various mainstream technologies. By drawing on pilot-scale and industrial application case studies, the paper identifies the key challenges and bottlenecks hindering the widespread adoption of new technologies, thereby accelerating the application and commercialisation of these technologies in the industrial deep desulphurisation of yellow phosphorus off-gas.
