Abstract
1324392 Zeolitic molecular sieve agglomerates UNION CARBIDE CORP 23 July 1970 [24 July 1969] 35661/70 Heading C1A Hardened agglomerates of zeolitic molecular sieve crystals are prepared by forming an initial agglomerate comprising compacted molecular sieve crystals, applying a uniform thin continuous coating of boehmite alumina particles to the agglomerate, impregnating the alumina coated agglomerate with an aqueous potassium silicate solution (2-4 wt. per cent solids) and then firing the impregnated agglomerate at a temperature (e.g. 1050‹ to 1220‹ F.) sufficient to set and harden the silicate. The boehmite alumina particles used have been thermally deactivated at 250‹ to 350‹ C. for from 0À75 to 1À5 hours, may be less than 300 U.S. mesh in particle size, and form a coating of thickness 1 micron to 0À003 inch. The potassium silicate solution may have a K 2 O : SiO 2 ratio by weight of 0À477 to 0À40 : 1, and from 0À03 to 0À07 pounds of solution solid may be used per pound of agglomerate. Colloidal silica in suspension may also be present in the silicate solution. The agglomerates may be bonded with 5-35 wt. per cent clay (e.g. attapulgite, kaolin, sepiolite, polygorskite, plastic ball clays, bentonite, montmorillonite, illite and chlorite). The agglomerates may be dried between impregnation and firing. In Example 1, Type 3A molecular sieve crystals (80 pts. by weight anhydrous) and attapulgus clay (20 pts. by weight anhy- .drous) were dry blended, water (21 parts) was then added, and spherical bodies were formed by tumbling. 2% By weight boehmite alumina (particle size = 44 microns), previously heated at 300‹ C. for l hour in air, was tumbled with the spherical agglomerates. The coated agglomerates were soaked for 6 hours at 70‹ F. in aqueous potassium silicate (solids content = 2À9%), dried, and fired at 625‹ C. for 30 minutes.
