摘要： A catalyst for exhaust gas purification is capable of purifying the hydrocarbons, nitrogen oxides and carbon monoxide present in the exhaust gas discharged from an internal combustion engine. The catalyst has a monolithic carrier and a catalyst layer containing Pd, Ba and a heat-resistant inorganic oxide, formed on the carrier. The amount of Pd supported on monolithic carrier is 100-300 g per ft3 of monolithic carrier (3.53×10−3 to 1.06×10−2 g per cc of monolithic carrier), the amount of Ba supported on monolithic carrier is 0.010-0.060 g per cc of monolithic carrier in terms of BaO, and the weight ratio of Pd and Ba as expressed as BaO is 1:2 to 1:10. This catalyst for exhaust gas purification is superior particularly in hydrocarbon purification for a low-temperature fuel-rich exhaust gas (such as exhaust gas emitted during cold start) of automobile.

摘要： A method for exhaust gas purification using an exhaust gas purification system including (a) an adsorbent for adsorbing hydrocarbons in internal combustion engine exhaust gas provided in the engine exhaust pipe, (b) at least one catalyst for reducing harmful substances present in the exhaust gas, provided in the exhaust pipe upstream of the adsorbent in the flow direction of the exhaust gas, (c) at least one catalyst for reducing harmful substances present in the exhaust gas, provided in the exhaust pipe down-stream of the adsorbent in the flow direction of the exhaust gas, (d) a first inlet for introduction of secondary air into exhaust gas, formed in the exhaust pipe upstream of the most downstream catalyst of the catalyst (b), and (e) a second inlet for introduction of secondary air into exhaust gas, formed in the exhaust pipe between the catalyst (b) and the most downstream catalyst of the catalyst (c). Secondary air is introduced from the first inlet at a time from engine start to activation of catalyst (b); when catalyst (b) has been activated, stopping secondary air introduction from the first inlet; meanwhile, introducing secondary air from the second inlet while the hydrocarbons of exhaust gas adsorbed by adsorbent (a) are desorbed therefrom as its temperature rises by the heat of the exhaust gas. This method effectively purifies the hydrocarbons discharged from an internal combustion engine in a large amount during cold start, without adversely affecting the purification of also-discharged NOx.

摘要： A ceramic honeycomb structure has an open frontal area of 50% to 85%, a porosity of 0.1% to 10%, and a proportion of the volume of pores of 1 &mgr;m or larger in diameter, in total pore volume, of 20% or more; a regenerative thermal oxidizer using the ceramic honeycomb structure. The ceramic honeycomb structure has a small porosity and, therefore, has a sufficient heat accumulation capacity and hardly causes floating by gas pressure; has controlled pore diameters and, therefore, hardly shows adsorption of VOC or the like, or rupture; and has controlled contraction and, therefore, has a large GSA.
