摘要：

Flue gas desulfurization characteristics of Mn-Ce metal oxides supported by ceramic-based diatomite and SBA-15 were systematically examined. The diatomite-supported sorbent (M2C2D6) achieved 96% desulfurization efficiency, which can be attributed to its robust mechanical integrity and high porosity. In contrast to the diatomite-supported sorbent, the SBA-15-supported counterpart (M2C2S6) exhibited more uniform active component dispersion, leading to a marked elevation in breakthrough sulfur capacity (T SC ) from 162 mg-SO₂/g-sorbent to 469 mg-...
