Molecular sieves are prepared by forming a reaction mixture slurry, spray
drying the reaction mixture slurry to form particles, and heating the
spray dried reaction mixture at a temperature and pressure sufficient to
cause crystallization of the molecular sieve. The reaction mixture
contains an organic templating agent capable of forming the molecular
sieve. The template may be added to the reaction mixture either by adding
all of the template prior to spray drying, or by adding a portion of the
template prior to spray drying with the remainder being added after spray
drying.
