摘要： A catalyst composition for purification of exhaust gas, comprises (a) high-silica zeolite having a Si/Al ratio of 40 or more which has been subjected to ion exchange with at least one metal selected from Pt, Pd, Rh, Ir and Ru, and (b) a heat-resistant oxide containing at least one metal selected from Pt, Pd, Rh, Ir and Ru. The catalyst composition is supported on a monolith carrier as a single layer or with the two components (a) and (b) as separate layers. The catalyst has high activity for exhaust gas purification even when it contains Rh, which is an expensive catalyst component, in a very small amount.

摘要： A reformer includes two or more catalyst units in the flow path, capable of generating hydrogen from a reactant fluid containing an organic compound or carbon monoxide, by catalysis. In the reformer, at least two of the catalyst units satisfy the following relationship: Heat capacity of the upstream-side catalyst unit ≤ Heat capacity of the downstream-side catalyst unit. The reformer is improved in the relationship between these catalyst units with respect to heat capacity. This improvement leads to improvement of the reformer in safety, heating characteristics during the start-up period, efficiency of hydrogen production and reduction in production of CO as the coproduct.

摘要： A method for exhaust gas purification by the use of a system for exhaust gas purification, which system includes (a) an adsorbent containing an adsorbent component capable of absorbing hydrocarbons present in the exhaust gas emitted from an internal combustion engine, provided in the exhaust pipe of the engine, (b) at least one catalyst containing a catalyst component capable of reducing harmful substances present in the exhaust gas, provided in the exhaust pipe at a site upstream of the adsorbent in the flow direction of the exhaust gas, (c) at least one catalyst containing a catalyst component capable of reducing harmful substances present in the exhaust gas, provided in the exhaust pipe at a site downstream 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 at a site 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 at a site between the catalyst (b) and the most downstream catalyst of the catalyst (c). The method includes introducing secondary air from the first inlet for a period from engine start to the activation of the catalyst (b) provided upstream of the adsorbent; at the timing when the catalyst (b) has been activated, stopping the introduction of secondary air from the first inlet; mean-while, introducing secondary air from the second inlet while the hydrocarbons of exhaust gas adsorbed by the adsorbent (a) are desorbed from the adsorbent (a) with the temperature rise of the adsorbent (a) brought about by the heat of the exhaust gas. This method for exhaust gas purification can effectively purify the hydrocarbons discharged from an internal combustion engine in a large amount during the cold start, without adversely affecting the purification of NOx also discharged.

摘要： A ceramic structure obtained by combining a plurality of sintered ceramic material segments (3a, 3b) having a thermal expansion coefficient of 3.0x10 / DEG C or more and integrating them, in which ceramic structure thermal impact-relieving zones (5a, 5b) capable of releasing the thermal impact applied are provided between the segments (3a, 3b) and the widths of the thermal impact-relieving zones (5a, 5b) in the sectional direction of the ceramic structure are various. This ceramic structure is capable of sufficiently release the thermal impact applied, without significantly reducing the effective sectional area of the structure or the overall strength of the structure, and can have the universality capable of coping with various applications and various materials.

摘要： A system for exhaust gas purification disposed in the exhaust pipe of an internal combustion engine, includes an adsorbent comprising a monolithic carrier and an adsorbent component having a hydrocarbon adsorptivity, loaded on the carrier, and a catalyst comprising a monolithic carrier and a catalyst component loaded on the carrier, having a purifiability for the harmful substances present in the exhaust gas emitted from the engine, the catalyst being provided downstream of the adsorbent in the flow direction of the exhaust gas. In the system, the adsorbent has a sectional shape satisfying the following relation: 1.2 ~ (major axis)/(minor axis) ~ 6.5 This system for exhaust gas purification enables the desorption of hydrocarbons from the adsorbent in a longer time and can remove the hydrocarbons generated during engine cold start, at a higher purification ratio.
