Claim 1
Independent Claim
114 words
A PROCESS FOR FORMING AN IMPROVED CRYSTALLINE ALUMINO-SILICATE ZEOLITE STRUCTURE WHICH COMPRISES SLURRYING CRYSTALLINE ALUMINO-SILICATE ZEOLITES IN WATER TO PRODUCE AN AQUEOUS SUSPENSION, SUBJECTING SAID SUSPENSION OF ZEOLITES TO SEVERE ATTRITION SO AS TO REDUCE THEIR AVERAGE PARTICLE SIZE TO LESS THAN 0.3 MICRON, DRYING A PORTION OF SAID SUSPENSION TO FORM ZEOLITIC PARTICULATE MASSES HAVING AN AVERAGE PARTICLE SIZE DIAMETER GREATER THAN 1 MICRON, ADMIXING SAID DRIED PARTICULATE MASSES WITH THE REMAINDER OF SAID ATTRITED AQUEOUS SUSPENSION, AND SUBJECTING THE ADMIXTURE OF THE PARTICULATE MASSES AND THE ATTRITED AQUEOUS SUSPENSION TO A DRYING STEP SO AS TO FORM ZEOLITE STRUCTURES OF A SIZE SUBSTANTIALLY LARGER THAN THE ORIGINAL PARTICLE SIZE OF SAID ZEOLITES.
