Title:
ALUMINA COMPOSITION FOR COATING CATALYST CARRIER, PRODUCTION THEREOF AND OBTAINED CATALYST CARRIER
Document Type and Number:
Japanese Patent JPS5851938
Kind Code:
A
Abstract:
Aqueous alumina coating compositions well adopted for directly impregnating/coating both ceramic and metallic catalyst supports to provide integral, both macroporous and microporous coatings therefor, which coated supports are useful for the fabrication of a wide variety of catalysts for catalyzing a broad spectrum of reactions, including those characterized by highly limited internal diffusion or by progressive catalyst poisoning, e.g., the treatment of exhaust gases, are comprised of water and a particulate alumina binder fraction dispersed therein, and an undispersed particulate alumina filler fraction therefor, said particulate alumina fractions being from 10 to 60% dispersed in the water, with the grain size distribution of the alumina particles comprising said undispersed filler fraction being such that the average diameter of said alumina filler particles ranges from 1 to 15 microns, and with at least 70% of such alumina filler particles having diameters ranging from one-half of the average diameter to twice the average diameter.
