The invention relates to the field of
molecular sieve preparation, and aims to provide a method for synthesizing an SSZ-13
molecular sieve through
solid-phase
grinding. The method for synthesizing the SSZ-13
molecular sieve through
solid-phase
grinding comprises the following steps: weighing a
silicon source, an aluminum source, an alkali source and a template agent for
crystallization reaction so as to obtain a
crystallization reaction product after the reaction is completed, cooling and washing till being neutral,
drying to obtain crude molecular
sieve powder, and
roasting the crude molecular
sieve powder for 5 hours in air of 550 DEG C, thereby obtaining a final product SSZ-13 molecular
sieve. The SSZ-13 molecular sieve with relatively good
crystallinity degree is synthesized through
solid-phase
raw material grinding under a
solvent-free condition, so that the use of
solvent water is reduced to the maximum extent, the synthesis
route only involves mixing synthesis steps of primary raw materials, the method is greatly simplified when being compared with a conventional method, the yield and the
utilization rate of a single kettle are both relatively increased, the production cost is greatly lowered, the
pollution to the environment is greatly reduced, and great industrial application prospect can be achieved.
