Abstract

PURPOSE: To prepare zeolite A having a round granular surface and uniform crystalline grains efficiently, by reacting an aqueous solution of sodium silicate with an aqueous solution of sodium aluminate, and aging and crystallizing the formed aluminosilicate gel under the forced diffusive state.
CONSTITUTION: An aqueous solution of sodium silicate containing 5W20% Na2O as a raw material is mixed continuously with an aqueous solution containing 5W 20% SiO2, 5W15% Na2O and 5W10% Al2O3 under a condition causing no back mixing to prepare a uniform gel. A tubular static mixing appartus is used for the purpose, and both solutions are injected into the apparatus simultaneously to prepare the uniform gel. The gelation must be carried out at a molar ratio between SiO2 and Al2O3 in the range of 0.5W2.5.
