Exhaust Gas Purifying Method And Exhaust Gas Purifying Apparatus For Internal Combustion Engine |
摘要 |
The invention provides a technology that enables to prevent sulfur components contained in reducing agent added from flowing into an NOx catalyst thereby keeping a high NOx removing rate. An S-trapping catalyst 11 for trapping sulfur components contained in exhaust gas discharged from an internal combustion engine 1 , an S-trapping catalyst 12 for trapping sulfur components contained in reducing agent added to the exhaust gas from which sulfur components have been trapped by the S-trapping catalyst 11 are provided, thereby preventing an NOx catalyst 14 from being poisoned by sulfur.
