Regeneration catalyst
WebUnlike a catalytic converter which is a flow-through device, a DPF retains bigger exhaust gas particles by forcing the gas to flow through the filter; however, the DPF does not retain small particles. Maintenance-free DPFs oxidise or burn larger particles until they are small enough to pass through the filter, though often particles "clump" together in the DPF reducing the … WebFeb 28, 2024 · Regeneration of Deactivated Catalysts. Several blocks of deactivated catalysts (25 mm long monolithic segment) were washed in 1000 mL 0.5 M sulfuric acid (SA) solution for 120 min and then washed in 1000 mL deionized water for 15 min. In some cases, different concentrations of sulfuric acid (0.05 M, 0.1 M, ...
