The technique for synthesizing powdered OFF-type zeolite of high phase purity and crystallinity has been developed. The effect of crystallization conditions on the characteristics of powdered OFF-type zeolite samples, namely, crystallinity, particle-size distribution, and adsorption of molecules has been studied. An increase in the crystallization temperature has been found to reduce the synthesis duration time; however it resulted in the formation of larger OFF-type zeolite crystals and aggregates thereof. It has been discovered than the particle size of the obtained OFF-type zeolite samples does not affect the adsorption of H2O molecules. On the coarse-crystalline samples the slower diffusion rate of n-С6Ð14 molecules into the zeolite channels is observed; it is associated with the larger size of the adsorbed substance molecules. And for yet larger С6Ð12 molecules the equilibrium adsorption capacity values are decreased.
