Sulfur dioxide purification has adverse effects on the environment and the human body. In this study, the dry desulfurization process from exhaust gas exhaust by dry DeSOₓ filter is investigated for constructing a sulfur-based capture-and-reuse system. The activated MnO₂ having a high-specific surface area (HSSA MnO₂) is utilized as an absorbent to indicate high SO₂ capture performance in the low-temperature region. To improve the capture performance, (SO₂ concentration, space velocity, and gas composite) is analysed on SO₂ capture performance of dry DeSOₓ filter. Results showed that SO₂ capture performance in high SO₂ concentration was constant regardless of space velocity. However, in low SO₂ concentration, the SO₂ capture performance decreased with increasing space velocity. Moreover, the presence of H₂O in the flow gas exhibited a beneficial effect on SO₂ capture performance.
