Abstract:
An exhaust gas purifying composition of the present invention contains zeolite that is BEA zeolite having an SiO 2 /Al 2 O 3  molar ratio of greater than 25 and 600 or less and containing phosphorus. Furthermore, the exhaust gas purifying composition preferably contains zirconium in addition to phosphorus. Furthermore, the zeolite has an SiO 2 /Al 2 O 3  molar ratio of from 30 to 150. The present invention provides an exhaust gas purifying composition having excellent HC adsorbability for exhaust gas purification in internal combustion engines such as gasoline engines.

Claim (Index 1):
An exhaust gas purifying composition comprising BEA zeolite which has an SiO 2 /Al 2 O 3  molar ratio of greater than 25 and 600 or less and which contains phosphorus and zirconium, wherein an amount of the phosphorus contained in the zeolite is such that a molar ratio (P/Al) thereof with respect to Al in the BEA zeolite is 0.5 or greater, and an amount of the zirconium contained in the zeolite is such that a molar ratio (Zr/Al) thereof with respect to Al in the zeolite is 0.25 or greater.
