摘要： Synthetic zeolite is produced by force feeding separate aqueous streams of sodium silicate and of an alkali metal aluminate into coaxial alignment with each other. The coaxially aligned solutions are then introduced into in an open space in coaxial fashion with one of the streams being injected from a nozzle. The open space constitutes a mixing zone in which the two streams come together and are thoroughly mixed to produce a precrystallized mixture. This mixture then passes in unimpeded fashion through an entrance port and into a crystallization reactor or vessel. The system used for conducting this operation thus serves the dual function of being a feeding system and a mixing system whereby the silicate and aluminate streams interact with each other before entering the crystallization reactor or zone. Intimate mixing is assured by virtue of the relatively small volume of the mixing zone and the higher velocity of the stream emanating from the nozzle.
