LSX molecular sieve – Low Silica X-type
Purpose:
■ Removing carbon dioxide: Even at extremely low partial pressures, it exhibits outstanding carbon dioxide adsorption capacity. ；
■ Remove moisture: Intensify the drying process of the air to prevent freezing and clogging of equipment in low-temperature areas. ；
■ Removal of hydrocarbons: Effectively adsorbs flammable and explosive components such as acetylene and ethane, ensuring production safety ；
■ Industrial gas purification: Used for sulfur removal in natural gas, and sulfur and water removal in liquefied petroleum gas (LPG), etc.
Characteristic:
Low Silica X-type molecular sieve is an artificial silicate-aluminate crystal with extremely high pore volume and specific surface area. Compared with ordinary 13X molecular sieves, it significantly enhances the adsorption capacity for polar molecules by reducing the silicon-aluminum ratio (SiO2/Al2O3 is close to 2). At the same time, the “no potassium” property ensures better thermal stability and mechanical strength under specific process conditions.
Compared to the ordinary 13X molecular sieve, the low-silicon, potassium-free 13X has the following remarkable advantages:
Ultra-high dynamic adsorption capacity: Due to the lower silicon-aluminum ratio, the number of effective active cations in the crystal cell increases, and its adsorption capacity for CO2 is 20%-40% higher than that of the ordinary 13X. Longer cycle life: Under the same air volume, it can extend the switching cycle, thereby reducing the energy consumption of the air pre-cooling system and heating system. Excellent kinetic performance: The adsorption speed is fast, and even at high gas flow rates (large processing volume), it can maintain a very narrow mass transfer zone. Outstanding thermal stability: The “potassium-free” design avoids the risks of high-temperature coking or strength reduction caused by potassium ions in certain specific working conditions, and has a longer service life (usually up to 3-5 years). Cost savings in equipment investment: Due to the high adsorption efficiency, the design volume of the adsorption tower can be reduced, and the floor area and infrastructure cost of the entire system can be decreased.
