Effect of mechanical treatment on properties of Si-Al-O zeolites

Abstract

in the work the results influence of mechanical treatment on morphology, specific surface area, and phase composition of natural zeolite of tokaj mountain deposits, synthetic zeolites sAPo-34, sct-323 are presented. specific surface area of the synthetic zeolites decreases during the mechanical activation in a planetary ball mill. the changes of the specific surface area of the natural zeolites corresponds to the curve of the developed specific surface as function of the milling time (rittinger-zone, aggregation-zone and agglomeration-zone). During the mechanical activation, it was observed an increase of system amorphisation by 8-10% for synthetic zeolites, by 40-45% for natural zeolite. results obtained represent scientific and practical interest, which can be used for further studies zeolites.
