Research of a type zeolite as well as zeolite membrane by microwave technique heating

Abstract

Effects of aging time and alkalinity as well as cation concentration (Na+) on the synthesis of A type zeolite and zeolite membrane were investigated in this paper. The results showed that aging time for synthesis of A type zeolite and zeolite membrane had remarkable influence and alkalinity could accelerate the formation of zeolite but was disadvantage to zeolite membrane synthesis. Cation concentration (Na+) also couldn't accelerate the synthesis of zeolite and zeolite membrane but it was probable an important factor to accelerate crystal growth. Moreover, more compact zeolite membranes could be synthesized by this method while the thickness of membrane was thinner than that of convention. Zeolites and zeolite membranes were characterized by XRD, TEM as well as IR characterization techniques.
