A METHOD FOR PREPARING A SUPPORTED CRYSTALLINE ALUMINOSILICATE COMPOSITION WHICH COMPRISES IMPREGNATING A SOLID, CAGE-LIKE SUPPORT CHARACTERIZED BY A POROSITY OF AT LEAST 0.05 CC./GRAM AND AN EFFECTIVE PORE DIAMETER WITHIN THE APPROXIMATE RANGE OF 0.1 TO 200 MICRONS WITH AN AQUEOUS REACTION MIXTURE FOR SYNTHESIZING SAID CRYSTALLINE ALUMINOSILICATE WHICH CONTAINS: (A) A SOURCE OF SILICA SELECTED FROM THE GROUP CONSISTING OF SILICA GEL, SILICA SOL, SILICIC ACID AND ALKALI METAL SALTS OF SILICIC ACID; (B) A SOURCE OF ALUMINA SELECTED FROM THE GROUP CONSISTING OF ALUMINA SOL, ACTIVATED ALUMINA, GAMMA ALUMINA, HYDRATED ALPHA ALUMINA, ALUMINA TRIHYDRATE AND ALKALI METAL SALTS OF ALUMINIC ACID; AND (C) A SOURCE OF ALKALI METAL OXIDE; MAINTAINING SAID SUPPORT IN CONTACT WITH SAID REACTION MIXTURE AT A TEMPERTURE IN THE APPROXIMATE RANGE OF 20 TO 200*C. FOR A PERIOD OF TIME BETWEEN ABOUT 15 MINTUES AND ABOUT 90 HOURS UNTIL CRYSTALS OF SAID ALUMINOSILICATE ARE FORMED AND GROW TO A SIZE NOT EXCEEDING THE MAXIMUM PORE DIAMETER OF SAID SUPPORT, WASHING THE RESULTING COMPOSITE FREE OF WATER-SOLUBLE MATTER AND DRYING.
