Carbon Molecular Sieves | intro
Carbon Molecular Sieves (CMS) are advanced carbonaceous adsorbents engineered for selective gas separation. Characterized by a uniform micropore structure, CMS excel in separating gas molecules based on differences in diffusion rates, making them a cornerstone of industrial processes like nitrogen generation. Produced from carbon-rich precursors such as coconut shells, coal, or polymers via pyrolysis and activation, CMS offer a sustainable and efficient solution for gas purification and separation.
Discover the power of carbon molecular sieves in nitrogen generation for efficient, cost-effective gas separation. Whether you’re curious about how do carbon molecular sieves work or seeking the best CMS for nitrogen generation, these advanced materials deliver high-purity N2 (up to 99.995%) via the carbon molecular sieve PSA process. With benefits like energy efficiency and durability, CMS outshine alternatives—perfect for industries needing reliable nitrogen supply.

Carbon Molecular Sieves | Structure and Properties
CMS are defined by their narrow pore size distribution, typically ranging from 3 to 5 Ångstroms (Å), which enables molecular sieving. This distinguishes them from activated carbon, which has a broader pore range (average ~20 Å). The micropore volume of CMS is approximately 0.15–0.25 cm³/g, with surface areas of 250–400 m²/g. Their slit-shaped pores, formed by planar aromatic structures, provide high selectivity by allowing smaller molecules (e.g., O2, 0.346 nm) to diffuse faster than larger ones (e.g., N2, 0.364 nm). CMS exhibit excellent mechanical stability (hardness >98 wt%) and thermal resistance, enduring pressure swings and high-temperature environments without degradation.
Carbon Molecular Sieves | how it works
CMS operate via kinetic separation, leveraging the differential adsorption rates of gas molecules. In a typical Pressure Swing Adsorption (PSA) system, compressed air is introduced to CMS-filled columns. Oxygen (O2), with its smaller kinetic diameter, is preferentially adsorbed into the micropores, while nitrogen (N2) passes through, yielding high-purity N2 (97–99.995%). The process cycles between adsorption (high pressure) and desorption (low pressure), regenerating the CMS for continuous operation. This mechanism is energy-efficient, requiring no heat input (heatless adsorbent regeneration), and is optimized by CMS’s uniform pore structure and high adsorption capacity.
