Abstract

Aluminosilicate zeolite ECR-1 was successfully obtained under hydrothermal condition at 100 °C by hydrothermal phase transition of zeolite Y in the absence of organic template. When n(Na₂O)/n(SiO₂) ratio in the starting aluminosilicate gel[n(SiO₂):n(Al₂O₃): n(Na₂O):n(H₂O)=10:1.0:2.5-3.3:200] was 0.33, the phase transition from zeolite Y to zeolite P occurred. However, when the n(Na₂O)/n(SiO₂) ratio was 0.25, zeolite Y was converted into zeolite ECR-1. In this case, zeolite Y was served as nutrient for the crystallization of zeolite ECR-1.
