METHOD TO TAILOR ZEOLITE SILICA-TO-ALUMINA RATIO
20230331561 · 2023-10-19 ·

The present disclosure is directed to a method of manufacture of zeolite. A sol-gel formulation includes a water-soluble fraction of ODSO as an additional component. The resulting products include zeolite with increased SAR relative to comparable sol-gel formulations without ODSO as a precursor. In addition, the SAR is increased by increasing the ODSO content during synthesis. In additional embodiments, zeolite yield is also increased.
