Abstract (en)

[origin: WO0141904A1] A process for treating an exhaust gas from a lean-burn internal combustion engine containing sulfur oxides (SOx) and at least one other atmospheric pollutant selected from HC, CO, NO and soot, which gas being untreated or having undergone some chemical and/or catalytic treatment, comprises the steps of absorbing a sulfate-forming SOx component in a solid absorbent material, passing gas containing SO2 to atmosphere and periodically replacing the absorbent material. A system for carrying out the process comprises an exhaust passage and a sulfate absorber (26) comprising a substrate supporting a solid material for absorbing a sulfate-forming component from SOx in the exhaust gas, which sulfate absorber is adapted to be replaceable.
