Carbon molecular sieves are primarily composed of elemental carbon, appearing as black cylindrical solids. They are excellent non-polar carbon materials with numerous micropores that have a strong affinity for oxygen molecules. These micropores enable the separation of oxygen and nitrogen from air using Pressure Swing Adsorption (PSA) systems to produce nitrogen gas. High-purity nitrogen is widely used in food preservation, electronics, chemical production, metal processing, and the pharmaceutical industry. JOOZEO's JZ-CMS carbon molecular sieves are available in various models. We recommend the most cost-effective model based on the customer's nitrogen production rate, purity requirements, and equipment conditions.
