According to 24 chemicalresearch report, Global Molecular Sieve for Air Separation Market size was valued at USD 247 million in 2024. The market is projected to grow from USD 255 million in 2025 to USD 327.95 million by 2032, exhibiting a CAGR of 3.20% during the forecast period. Demand continues to accelerate due to rising industrialization, stricter environmental regulations, and increasing oxygen consumption in healthcare and manufacturing sectors.

Molecular sieves play a critical role in cryogenic air separation units (ASUs) by removing water vapor, carbon dioxide, and hydrocarbons from compressed air before distillation. Their exceptional adsorption capacity and thermal stability make them indispensable for producing high-purity oxygen (99.5%+), nitrogen, and argon. With industries increasingly prioritizing energy efficiency and purity standards, advanced molecular sieve solutions are gaining traction.
