The damage of dust to catalysts in flue gas acid production

2025-12-30View Original

Thread Content

The damage caused by dust to catalysts in flue gas acid production: The surface of catalysts consists of numerous micropores. When dust from the flue gas enters the converter, most of it deposits directly on the surface of the catalysts, while the remaining part gradually penetrates into these micropores, leading to a gradual decline in the catalyst’s activity and an increase in the resistance to gas flow through the micropores; At the same time, dust reacts with acid mist to form sulfates, causing the catalyst to clog and leading to uneven gas distribution within the converter, as well as a gradual increase in the resistance of the conversion system.
