Ferrierite type (FER) zeolite layers have been successfully synthesized on a porous cordierite support from clear solutions, using ethylenediamine as structure directing agent. The use of a clear solution avoids the support channel plugging and promotes a stable and homogeneous zeolitic layer, without any pre-treatments of the support surface. The amount of deposited zeolite has been quantified by the increasing weight of the sample and it is around 70% and calculated layer thickness value is 23 mm.

Abstract

Ferrierite type (FER) zeolite layers have been successfully synthesized on a porous cordierite support from clear solutions, using ethylenediamine as structure directing agent. The use of a clear solution avoids the support channel plugging and promotes a stable and homogeneous zeolitic layer, without any pre-treatments of the support surface. The amount of deposited zeolite has been quantified by the increasing weight of the sample and it is around 70% and calculated layer thickness value is 23 mm. The adherence of zeolite layer has been evaluated measuring the weight losses of samples, caused by exposing them to repeated air flows and heating cycles. The different post-synthesis thermal treatments affect the homogeneity of the zeolitic layer
