Disclosed are a molecular sieve catalyst and a preparation method thereof to produce light olefins from cracking naphtha catalytically in severe environments of high temperature and high moisture. In detail, the catalyst is prepared by spray- drying and calcining the mixed slurry, in which 0.01~5.0 wt% of MnO2 and 1~15 wt% of P2O5 are simultaneously imbedded in catalyst which consists of zeolite, clay and inorganic complex. According to the present invention, the method that manganese and phosphate are imbedded simultaneously in zeolite and inorganic complex is used to increases thermal-stability of obtained spherical catalyst, and increase olefin yield of cracking hydrocarbon such as naphtha by protecting acid-site of zeolite. To synthesize the required catalyst, the important procedures are mixing ratio and mixing sequence of Mn, P, zeolite, and inorganic complex.

La présente invention concerne un catalyseur utilisé dans la production d'une oléfine légère par craquage catalytique de naphta dans des conditions agressives de hautes températures et de haute humidité. Plus particulièrement, l'invention concerne un catalyseur pour le craquage catalytique d'un hydrocarbure, utilisé dans la production d'une oléfine légère, ainsi qu'un procédé de production de ce catalyseur. Ledit catalyseur est préparé par séchage par pulvérisation et par cuisson d'une pâte mélangée de façon que de 0,1 à 0,5% en poids de MnO2 et de 1 à 15% en poids de P2O5 soient simultanément supportés sur zéolithe, argile et oxydes inorganiques. Le catalyseur de l'invention permet non seulement d'améliorer la stabilité hydrothermique d'un catalyseur sphérique obtenu par modification du zéolithe et des oxydes inorganiques avec du manganèse et du phosphore de façon simultanée, mais également de protéger les sites acides du zéolithe. L'invention permet ainsi de réaliser une production en masse et d'augmenter le rendement économique au moyen d'un simple procédé de production de ce catalyseur.
