Solarization of the zeolite production: Calcination of kaolin as proof-of-concept

The current production of zeolites from natural sources requires high temperatures to achieve a phase change in the feedstock materials. Thermal processes such as calcination are energy-consuming and industry relies on fossil fuels generate necessary heat, which is neither sustainable nor environmental. This study presents for first time treatment aluminosilicate clay kaolin solar reactor produce metakaolins that eligible precursors zeolite synthesis. Kaolin was loaded rotary kiln simulator used at 700–1000 °C 2 h. After process, solar-produced were synthesize 4 A 13X by hydrothermal route. kaolin, metakaolin, product samples obtained analyzed XRD, XRF, FTIR, FE-SEM. Results show solar-calcined good efficient conventionally calcined one terms supplying metakaolin Often disregarded researchers, high-temperature proved be an alternative way synthesis without using extra silica source, achieved time. overall results suggest mass meta forms minerals value-added products zeolites.
