Abstract
A moisture adsorbing devicecomprising a type Y zeolite, and an NOadsorbing devicebeing put in place on an exhaust-gas downstream side of the moisture adsorbing device, and comprising a zeolite that includes a transition metal ion in the cation exchange sites are included. In NOadsorbing apparatuses, since the less the moisture content in exhaust gases is the more the NOadsorbing capability improves, the NO adsorbing capability in low-temperature region is improved especially by means of the combination with a moisture adsorbing device that comprises a type Y zeolite whose AlOproportion is great and whose moisture adsorbing amount is great compared with the other zeolites.
