Synthesis of a high‐permeance NaA zeolite membrane by microwave heating
Zeolite membranes with high permeance and separation factors are highly desirable for
practical applications. Although, in the past, very good separation factors have been
obtained, it has proved difficult to achieve a high permeance. Here a comparative study of
microwave versus conventional heating in the hydrothermal synthesis of NaA zeolite
membranes is made. It is demonstrated that membranes prepared by microwave heating
have not only a higher permeance but also a considerably shorter synthesis time. These …

Zeolite membranes with high permeance and separation factors are highly desirable for practical applications. Although, in the past, very good separation factors have been obtained, it has proved difficult to achieve a high permeance. Here a comparative study of microwave versus conventional heating in the hydrothermal synthesis of NaA zeolite membranes is made. It is demonstrated that membranes prepared by microwave heating have not only a higher permeance but also a considerably shorter synthesis time. These observations are rationalized by examining the mechanism of membrane formation.
