| titleOfInvention | Exhaust gas purification method and exhaust gas purification apparatus for internal combustion engine |
| abstract | In an exhaust purification apparatus or exhaust purification method, a sulfur absorbent is disposed upstream of a nitrogen oxide storage exhaust purification catalyst so as to absorb and remove sulfur contained in exhaust gas. Increase the sulfur absorption performance of the material. In an exhaust gas purification method or an exhaust gas purification device for purifying exhaust gas of an internal combustion engine with a nitrogen oxide storage type exhaust gas purification catalyst, Sr and Ti are mainly components before the exhaust gas flows into the exhaust gas purification catalyst. The sulfur component contained in the exhaust gas is absorbed and removed by the sulfur component absorbent comprising the complex oxide or the complex oxide further containing K. Since the sulfur absorbent made of this composite oxide has an extremely high sulfur absorption capacity, the process of regenerating the sulfur absorbent is unnecessary or the frequency of the treatment can be reduced. The decrease in activity can be suppressed. [Selection] Figure 1 |
