Beschreibung
Zusammenfassung:	The invention relates to a modified in-situ crystallization Y type molecular sieve/matrix composite material, the surface of which is loaded with 0.001 to 5.0% by weight of RE2O3, 0 to 3.0% by weight of SiO2, 0 to 3.0% by weight of Al2O3 and 0 to 3.0% by weight of MgO. The composite material is prepared by adjusting pH of kaolin in-situ crystallization Y type molecular sieve/matrix material to 8-11 by using a solution containing one or more of soluble glass, sodium metaaluminate and magnesium hydroxide, or ammonia water in separate steps or in combination after ammonium exchange and/or rare earth exchange, stirring, filtering, washing, drying, roasting and exchanging with ammonium.
