Patent number: 5989518Abstract: Applicants have developed a continuous process for synthesizing various molecular sieves. The process enables one to control both the particle size and particle size distribution. Any of the molecular sieves represented by the empirical formula on an anhydrous basis: rR.sub.2 O:(Si.sub.x Al.sub.y P.sub.z)O.sub.2, where R is at least one templating agent, "r" "x" "y" and "z" are the mole fractions of R, Si, Al and P respectively, can be prepared using this process.
