Molecular sieves are porous materials used to separate molecules based on size and shape. They consist of tiny pores that allow smaller molecules to pass through while larger ones are trapped. This characteristic makes molecular sieves crucial in various applications, from gas purification to catalysis.

The most common types of molecular sieves are zeolites, silica gels, and activated carbon. These materials efficiently adsorb gases and liquids, making them essential in industrial processes such as drying, refining, and treating natural gas. Molecular sieves help enhance product quality and process efficiency.

Innovations in molecular sieve technology continuously improve their performance and application range. Researchers focus on developing advanced materials with precise pore sizes for specialized uses like environmental protection and medical treatments, expanding their benefits and potential.
