Abstract
(EN)
Provided is a CHA-type zeolite that is highly crystalline and more suitable for use as a catalyst or a catalyst carrier as compared with conventional CHA-type zeolites, in particular, the ones that are obtained using only ADA salt as an organic structure-directing agent. This CHA-type zeolite satisfies any of the following: the molar ratio of silica with respect to alumina is not lower than 10.0 but lower than 20.0, while the molar ratio of silanol group with respect to silicon is 0.15×10-2-0.50×10-2; the molar ratio of silica with respect to alumina is 20.0-35.0, while the molar ratio of silanol group with respect to silicon is 0.15×10-2-1.10×10-2; the molar ratio of silica with respect to alumina is higher than 35.0 but not higher than 45.0, while the molar ratio of silanol group with respect to silicon is 0.15×10-2-1.65×10-2; or the molar ratio of silica with respect to alumina is higher than 45.0 but not higher than 55.0, while the molar ratio of silanol group with respect to silicon is 0.15×10-2-1.80×10-2.

L'invention concerne une zéolite de type CHA qui est hautement cristalline et plus appropriée pour une utilisation en tant que catalyseur ou support de catalyseur par rapport aux zéolites de type CHA classiques, en particulier, celles qui sont obtenues à l'aide uniquement d'un sel d'ADA en tant qu'agent dirigeant la structure organique. Cette zéolite de type CHA satisfait à l'une quelconque des conditions suivantes : le rapport molaire de la silice par rapport à l'alumine n'est pas inférieur à 10,0 mais inférieur à 20,0, alors que le rapport molaire du groupe silanol par rapport au silicium est de 0,15×10-2-0,50×10-2 ; le rapport molaire de la silice par rapport à l'alumine est de 20,0-35,0, alors que le rapport molaire du groupe silanol par rapport au silicium est de 0,15×10-2-1,10×10-2 ; le rapport molaire de la silice par rapport à l'alumine est supérieur à 35,0 mais pas supérieur à 45,0, alors que le rapport molaire du groupe silanol par rapport au silicium est de 0,15×10-2-1,65×10-2 ; ou le rapport molaire de la silice par rapport à l'alumine est supérieur à 45,0 mais pas supérieur à 55,0, alors que le rapport molaire du groupe silanol par rapport au silicium est de 0,15×10-2-1,80×10-2.
