In the study, natural zeolite—clinoptilolite (VSK PRO-ZEO, Vranov nad Topľou, Slovakia)—and synthetic MFI (Module 85.7, Clariant, Munich, Germany) zeolite were used as adsorption materials. In the …
ZSM-5 zeolite (Si/Al = 15) was supplied by Zeolyst International in the ammonium form (CBV3024E), and the H-form of the zeolite material was obtained by calcination in air at 550 °C (2 °C min ...
Natural zeolite was subjected to preliminary mechanical treatment by grinding granules in a mortar and sifting. The natural zeolite powder was then purified by washing it with distilled water and heated at 70°C for 8 h while stirring at 500 rpm to remove water-soluble impurities. Natural zeolite was dried at a temperature of 105°C for 10 h.
The milling technology applied in mechanical activation has a significant impact on the processing properties of natural zeolites, and it is recognized as an up-and-coming and eco-friendly process ...
This article describes the production of nanoparticles of Chilean natural zeolite, using three size reduction methods: Ball mill, microgrinding, and microfluidization. ... For M and C, there is a slight decrease in peak intensity. Therefore, the grinding process causes a decrease in intensity and increases the peak width, from the first ...
1. Introduction. Separation processes are of extremely high importance for our society, comprising 10–15% of the global energy use and 40–90% of the total process cost. 1,2 On one hand, most of the existing chemical processes do not yield products with the desired purity, directly suitable for further use. This is the case of petrochemical products or …
