Used primarily for drying gases and liquids, particularly in the petrochemical industry, to remove water and other small molecules. They are essential in the purification of natural gas, ensuring that moisture is effectively eliminated to prevent freezing in pipelines. In the production of ethanol, they help dehydrate the ethanol-water mixture to achieve high-purity ethanol. They are also employed in the packaging of pharmaceuticals, electronics, and other moisture-sensitive products to maintain a dry environment. Additionally, they play a role in the insulation of double-pane windows, where they adsorb any residual moisture to prevent fogging. Their selective adsorption properties make them valuable in separating molecules based on size in various industrial processes.
