摘要： A catalyst for purifying exhaust gases comprises a catalyst carrier made of potassium titanate and a noble metal loaded on the catalyst carrier. The catalyst carrier is substantially free from alumina. This catalyst can oxidize at least hydrocarbons in exhaust gases at a high catalytic activity even at low temperatures, and at the same time can suppress SO.sub.2 from converting into sulfates. This catalyst does not employ substance like alumina exhibiting solid acidity as a catalyst carrier. Further, this catalyst can be used for purifying exhaust gases from diesel engines to suppress particulates and sulfates from being emitted, and to improve conversions of hydrocarbons and carbon monoxide.

摘要： A catalyst for purifying exhaust gases includes a porous support, an NO.sub.x storage component including at least one member selected from the group consisting of alkaline-earth metals, rare-earth elements and alkali metals, and loaded on the porous support, a noble metal catalyst ingredient loaded on the porous support, and disposed adjacent to the NO.sub.x storage component, and ceria (CeO.sub.2) disposed away from the noble metal catalyst ingredient. By disposing the noble metal catalyst ingredient adjacent to the NO.sub.x storage component, the reduction reactions of NO.sub.x can be facilitated in fuel-rich (i.e., oxygen-lean) atmospheres without being interfered by the ceria. By disposing the ceria away from the noble metal catalyst ingredient, oxygen, which has been stored thereon in fuel-lean (i.e., oxygen-rich) atmospheres, can be released from the ceria at a controlled rate in a controlled amount in fuel-rich (i.e., oxygen-lean) atmospheres, and thereby the released oxygen can be inhibited from reacting with HC and CO in fuel-rich (i.e., oxygen-lean) atmospheres. Thus, the catalyst is improved in terms of NO.sub.x purifying performance.
摘要翻译：用于净化废气的催化剂包括多孔载体，包含选自碱土金属，稀土元素和碱金属中的至少一种的负载在多孔载体上的NOx储存组分，贵金属催化剂负载在多孔载体上并且邻近于NOx储存组分设置的成分和远离贵金属催化剂成分的二氧化铈（CeO 2）。通过将贵金属催化剂成分配置在与NOx存储成分相邻的位置，可以在不受二氧化铈干扰的情况下，富含燃料（即贫氧）的气氛中的NOx的还原反应变得容易。通过将二氧化铈置于贵金属催化剂成分之外，其中储存在贫燃料（即富氧）气氛中的氧可以以受控的量在二氧化铈中以富含燃料的方式从二氧化铈中释放出来（即，贫氧）气氛，从而可以抑制释放的氧与富含燃料（即贫氧）气氛中的HC和CO反应。因此，NOx净化性能提高了催化剂。
