Effect of Cation Exchange on the Performance of Clinoptilolite Mineral in the Ethanol Dewatering Process

Effect of Cation Exchange on the Performance of Clinoptilolite Mineral in the Ethanol Dewatering Process

This study describes the effect of cation exchange (Ni 2+ and Ca 2+ ) on the adsorption capacity and breakthrough time of a natural zeolite (clinoptilolite) employed in the ethanol dewatering process. The results obtained showed that modification of clinoptilolite (Clin) by cation exchange led to a...

The results obtained showed that modification of clinoptilolite (Clin) by cation exchange led to a decrease in the breakthrough time and water adsorption capacity in the order: Ca-Clin > Ni-Clin > Clin. In addition, characterization of the prepared clinoptilolite samples by BET, XRD and SEM techniques showed that no degradation of crystallinity had occurred, although the pore volumes of both cation-exchanged samples had increased as well as the surface area of the Ni-Clin sample.https://doi.org/10.1260/0263-6174.29.9.861
