A777 SO₂ Selective Reduction to Sulfur Catalyst

A777 SO₂ Selective Reduction to Sulfur Catalyst As foreign trade director of Shandong Xunda Catalyst, I communicate with many plant operators suffering high energy consumption from conventional tail‑gas hydrogenation units. Traditional hydrogenation reactors convert SO₂ into H₂S instead of elemental sulfur, bringing extra load for downstream absorption and regeneration towers. Our A777 SO₂ Selective Reduction to Sulfur Catalyst, supported by Patent Application No.200810237813.7, selectively reduces SO₂ directly into elemental sulfur inside hydrogenation reactors. The generated elemental sulfur can be cooled and collected in liquid sulfur storage tanks. Different from common tail‑gas hydrogenation catalysts, A777 avoids converting sulfur dioxide to hydrogen sulfide. It effectively raises total sulfur recovery rate of the whole unit. Operating temperature is kept at 160‑200℃, the system only needs heat exchange without additional heating furnace, which greatly cuts energy consumption. Hy…
