Title
(EN) ALUMINOSILICATE ZEOLITE INTERGROWTHS
(FR) ENCHEVÊTREMENTS DE ZÉOLITE D'ALUMINOSILICATE
Abstract
(EN)
The present disclosure provides a method of making zeolite intergrowths. In one embodiment, the present disclosure provides a method of making an AEI-based material, including the steps of: preparing a mixture of water, an alumina source, a silica source, a CHA structure directing agent, and an AEI structure directing agent, wherein the molar ratio of the CHA structure directing agent to the AEI structure directing agent is from about 1:1 to about 1:15; heating the mixture at a temperature sufficient to promote formation of crystals; and calcining the crystals at a temperature of from about 450 ºC to about 750 ºC to obtain a product, wherein no halide-containing reagent is employed. The AEI-based materials of the present disclosure may find particular use in selective catalytic reduction of NOx in exhaust gas streams.

La présente invention porte sur une méthode de fabrication d'enchevêtrements de zéolithe. Dans un mode de réalisation, la présente invention concerne une méthode de fabrication d'un matériau à base d'AEI, comprenant les étapes consistant à : préparer un mélange d'eau, d'une source d'alumine, d'une source de silice, d'un agent d'orientation de structure CHA, et d'un agent d'orientation de structure AEI, le rapport molaire de l'agent d'orientation de structure CHA à l'agent d'orientation de structure AEI étant d'environ 1 : 1 à environ 1 : 15 ; chauffer le mélange à une température suffisante pour favoriser la formation de cristaux ; et calciner les cristaux à une température d'environ 450°C à environ 750°C pour obtenir un produit, aucun réactif contenant des halogénures n'étant employé. Les matériaux à base d'AEI de la présente invention peuvent trouver une utilisation particulière dans la réduction catalytique sélective de NOx dans des flux de gaz d'échappement.
