| 英文摘要 | The COS hydrolysis and sorption catalyst was prepared by exhausted activated coke (EAC) produced in the activated coke purification process in the moving bed. Combining with the results characterized by multiple methods (XRD, TG, BET, TPD, FTIR, SEM, and XPS), it was found that the more developed pore structures and more abundant surface groups appeared in the EAC, and the specific surface area reached 445.38 m2/g. The effects of different alkali loading and process parameters on COS catalytic hydrolysis efficiency were investigated, and the results showed the activity was strongest when the NaOH loading was 0.450% at 100 which the breakthrough sulfur capacity reached 126.58 mg/g. The analysis of the sample after reaction showed that the COS mainly exists as S in the waste coke. This sulfur fixation method increases the sulfur capacity and provides a new way for the cascade utilization of waste coke and sulfur resource utilization. 漏 2022, Editorial Board of CIESC Journal.
