This invention is directed to a molecular sieve having acid catalyst sites and a method of maintaining the acid catalyst sites of a template-containing silicoaluminophosphate molecular sieve. The method comprises providing a template-containing silicoaluminophosphate molecular sieve and heating the molecular sieve in an oxygen depleted environment under conditions effective to maintain or preserve the number of acid catalyst sites. The heated molecular sieve exhibits at least one peak in the infrared region in a range of from 3630 cm-1 to 3580 cm-1. Preferably, the heated molecular sieve exhibits a combined peak area in the 3630 cm-1 to 3580 cm-1 range of at least 10 % of a total peak area of all peaks in an infrared region between 4000 cm-1 to 3400 cm-1.

L'invention concerne un tamis moléculaire possédant des sites de catalyseur acide et un procédé pour maintenir les sites de catalyseur acide d'un tamis moléculaire contenant un modèle à base de silico-aluminophosphates. Le procédé consiste à utiliser un tamis moléculaire contenant un modèle à base de silico-aluminophosphates qui sera chauffé dans un environnement pauvre en oxygène dans des conditions efficaces pour maintenir ou préserver le nombre des sites de catalyseur acide. Le tamis moléculaire chauffé manifeste au moins une crête en infrarouge dans une gamme entre 3630 cm(-1) et 3580 cm(-1). De préférence, le tamis moléculaire chauffé manifeste une zone de crête combinée dans une gamme entre 3630 cm(-1) et 3580 cm(-1) d'au moins 10 % d'une zone de crête totale de toutes les crêtes dans une zone infrarouge entre 4000 cm(-1) et 3400 cm(-1).
