| titleOfInvention | Device for Purifying Oxygen Rich Exhaust Gas |
| abstract | The present invention relates to an apparatus (catalyst converter) for purifying exhaust gas. This apparatus has a first catalyst for purifying NO x in exhaust gas. This first catalyst contains first and second powders. The first powder has a porous carrier and at least one precious metal supported on the porous carrier. At least one precious metal is selected from platinum, palladium and rhodium. The second powder is a formula (Ln 1-α A α ) 1-β BO δ , wherein α is a number greater than 0 and less than 1, β is a number greater than 0 and less than 1, δ is a number greater than 0, Ln is at least one first element selected from La, Ce, Nd and Sm, A is at least one second element selected from Mg, Ca, Sr, Ba, Na, K and Cs, B is Fe, Co, And at least one third element selected from Ni and Mn). This device has improved the purification ability of NO x contained in the oxygen rich exhaust gas. |
