Thermal Energy storage capacity on different types of zeolites

摘要

In this study, the quality and thermal storage capacity of different types of zeolites have been analysed. The main objective of this work is to evaluate the thermal storage capacity of different types of zeolites exposed to hydrothermal control, resulting in an assessment of their thermal storage potential, based on the cationic exchange inside their cells. Different lab experiments have been carried out, in which the behaviour of each sample has been evaluated under different conditions of drying (muffle, stove and desiccators) and operation, defining the thermal storage capacity for the different cases. A specific prototype has been designed for this purpose, which consists in different specific reactors for each zeolite type, including a sample storage chamber. "ThermaCAM SC660 Wes (TC)" results obtained for the different zeolites at different conditions, reveal high cationic exchange capacity for all types of zeolites. Drying and cooling conditions in the absence of humidity have been seen to influence results in a high extent, as well as the adequate design of the reactor, to provide effective air friction with the zeolite sample.
