    摘要： This catalyst support aims to improve heat resistant and durability by highly dispersing an NO.sub.x storage component. This catalyst support is produced by mixing a solution of a chemical compound including at least one element of alkali metals, alkaline-earth metals, and rare-earth elements with a solution of oxide sol of at least one metal of group IIIb, group IVa, and group IVb in the periodic table to prepare a mixed sol solution, forming the mixed sol solution into gel, and drying and calcining the gel. The obtained catalyst support is amorphous and attains a high specific surface area even when calcined at elevated temperatures, so that the catalyst support is superior in heat resistance.

    摘要： A high heat-resistant catalyst support comprises an amorphous composite oxide which is constituted by:(i) an NOx storage component comprising an oxide of at least one element selected from the group consisting of alkali metals, alkaline-earth metals and rare-earth elements,(ii) alumina (Al.sub.2 O.sub.3); and(iii) at least one element selected from the group consisting of titania (TiO.sub.2), zirconia (ZrO.sub.2) and silica (SiO.sub.2).Furthermore, TiO.sub.2, ZrO.sub.2 and SiO.sub.2 are acidic, and at least one element selected from the group consisting of TiO.sub.2, ZrO.sub.2 and SiO.sub.2 is highly dispersed to form composite. So, SOx having acidity is prevented from approaching the NOx storage component, and sulfur poisoning is prevented. Moreover, bonding force of the NOx storage component to the catalyst support strengthens, and the NOx storage component is prevented from being scattered.
