Abstract

PURPOSE: Sodium silicate and sodium aluminate are subjected to the continuous reaction at a specific ratio without back mixing to produce an A-type zeolite of round crystalline particles with uniform particle size distribution.
CONSTITUTION: An aqueous solution of sodium silicate containing 5W50% of Na2O and 5W20% of SiO2 and an other aqueous solution of sodium aluminate containing 5W15% of Na2O and 5W15% of Al2O3 are fed into a small-volume mixer- type reactor with high agitation efficiency so that the molar ratio of SiO2/Al2O3 becomes 1.5W2.5. Then, the reaction is effected without back mixing so that the average residence time defined by the equation becomes 10sec or lower where θ is the average residence time in second, V is the capacity of the reactor in liter, a and b are the feed rate of the aqueous sodium silicate and sodium aluminate respectively in 1/sec. Then, the reaction mixture is aged at 50W150°C fpr 1W10hr to cause crystallization, the resultant A-type zeolite is filtered and the mother liquor separated is recycled to the preparation stage of the aqueous sodium silicate and/or sodium aluminate.
