[size=3][font=MontserratRegular, Arial, sans-serif, serif]Molecular sieves are a crucial class of synthetic crystalline materials characterized by their exceptional adsorption properties. These materials, primarily composed of metal aluminosilicates, have a unique three-dimensional interconnecting network of silica and alumina tetrahedra. Through a process of dehydration, these structures form uniform cavities, making them highly effective in adsorbing molecules based on size exclusion. Due to their versatile adsorption capabilities, molecular sieves are extensively utilized in various industrial applications, such as gas and liquid purification, dehydration, and separation processes. This article delves into the properties, applications, and regeneration techniques of different types of molecular sieves, including 3A, 4A, 5A, and 13X.[/font][/size]
