Heat-resistant support for catalysts and the production thereof |
摘要 |
<p>This catalyst support aims to improve heat resistant and durability by highly dispersing an NOX 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.</p> |
