Abstract

1,131,764. Cracking catalyst. W. R. GRACE & CO. 25 May, 1966 [26 May, 1965], No. 23463/66. Divided out of 1,103,405. Heading B1E [Also in Division C5] A process for preparing a silica-alumina and zeolite cracking catalyst comprises (I) gelling an alkali metal silicate solution having a silica-alkali metal oxide weight ratio of 3:1 to 4:1 with CO 2 , (II) adding a solution of an aluminium salt in a quantity sufficient to provide at least 13% active alumina in the final catalyst and precipitating alumina therefrom into the gelled silicate to provide a silica-alumina composite, (III) filtering the composite (IV) adding to the composite a quantity of the ultra-stable synthetic zeolite defined in claim 1 of Specification 1,103,485 (i.e. Z14US), (V) spray drying, washing, and redrying the final product. The zeolite Z14US may have a silica-alumina mole ratio of 3.5:1 to 7:1, and may be added in sufficient quantity to provide 5 to 25% by weight of the total catalyst composition. Step (V) may include washing with distilled water at a pH above 7 to remove sodium and sulphate impurities.
