    摘要: A molecular sieve catalyst and a preparation method thereof to produce light olefins from catalytically cracking naphtha in severe environments of high temperature and high moisture, are disclosed. In detail, the catalyst is prepared by spray-drying and calcining the mixed slurry, in which 0.01~5.0 wt% of MnO 2 and 1~15 wt% of P 2 O 5 are simultaneously embedded in catalyst which consists of zeolite, clay and inorganic complex. According to the present invention, the method that manganese and phosphate are embedded simultaneously in zeolite and inorganic complex is used to increase 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.
