Eco-friendly synthesis of zeolite A from synthesis cakes prepared by removing the liquid phase of aged synthesis mixtures

Abstract

Zeolite A can be synthesized through hydrothermal reaction of a synthesis cake prepared by removing the liquid phase from a synthesis mixture. The volume and weight of the synthesis cake prepared using a filter press were about one-eighth and one-fourth those of the mixture, respectively. This implies that the reactor volume and energy input required for the hydrothermal reaction can be reduced by the same respective factors, allowing the eco-friendly synthesis of zeolites.
