A molding made of a thermoplastic resin composition that comprises a thermoplastic resin component and an elastomer component partly blending in with each other is continuously heated at a temperature higher than 120&#xb0; C. but lower than a melting point of each of the two components for at least one hour so as thereby to cause the thermoplastic resin component to separate and precipitate in the elastomer component.

A catalyst for lowering NOx concentration in an exhaust gas is disposed in an exhaust gas passage of an engine. The catalyst composed of a catalyst layer formed on a substrate. A NOx absorber that absorbs NOx when an oxygen concentration in the exhaust gas is high and releases NOx when the oxygen concentration drops, and a precious metal for reducing NOx are supported on a support material as catalyst components, and the NOx absorber includes Ba, K, Sr, and Mg. By lowering the oxygen concentration in the exhaust gas and raising a temperature of the NOx absorber when sulfur component is absorbed excessively in the NOx absorber, it is possible to regenerate the catalyst from the S poisoning.
