Binder-free syntheses of high-performance zeolites A and X from kaolin
Abstract The crystallization behavior of metakaolin (Al2Si2O7) at 25–100°C in solutions of sodium hydroxide and sodium silicate with different concentrations was studied, and the conditions for its conversion into finely divided, high-crystallinity zeolites of types A and X were determined. On the basis of the product zeolites and kaolin, procedures were developed for the preparation of pelleted, binder-free materials as polycrystalline accretions of zeolites A and X, which do not rank below pelleted zeolites obtained from synthetic feedstock.
