Facile synthesis of zeolites under an atmospheric reflux system

Traditionally zeolites are produced under long aging processes and high autogenous pressure reactions associated with a lot of safety concerns and explosion risks. Herein, a facile zeolite synthesis method under atmospheric pressure using a reflux system is reported. The zeolite gel crystallizes rapidly under the synthesis conditions of heating, stirring, and reflux in an oil bath. We have successfully synthesized LTA, FAU, MFI, and BEA zeolites. This technique not only eliminates the potential risks associated with pressure vessels but also greatly improves the synthesis rate and speeds up the production cycle. This synthesis strategy provides a new, safe and rapid way of synthesizing zeolites. • Safe synthesis of various zeolite by reflux system. • The synthesis of zeolite under atmospheric reflux system is faster than the conventional method. • Different synthesis methods of zeolite in reflux system are introduced in detail.
