Modeling and Simulation of a Zeolite Heat Storage with Binderless Zeolites

Abstract

Zeolite heat storages are one measure to contribute to the German Climate Change Act and reduce greenhouse gas emissions in the heating sector. However, due to the challenging process engineering, those storages did not reach a commercial breakthrough yet. To overcome this obstacle, intensive process simulation work is required. Thereby, the simulation models have to pay attention to recent innovations regarding the zeolite synthesis. One of those innovations is the preparation of binderless zeolites. Behind this background, it was achieved by the present work to develop and validate a simulation model for zeolite-based heat storage processes using binderless zeolites of type NaY.
