SO2 reduction for sulfur production by CO over Ce-Al-Ox composite oxide catalyst

Catalysis Communications, 2023
The optimal catalyst 10%Ce-Al-Ox combined the advantages of CeO2 and Al2O3, and 10%Ce-Al-Ox exhibited higher than 98% SO2 conversion and higher than 86% sulfur yield in the temperature range of 425–500 °C.
