Long Adsorption Carbon Molecular Sieve

Long adsorption carbon molecular sieve is specifically engineered for PSA nitrogen generators that operate with high flow rates and lower switching frequencies. Through precise optimization of internal micropore distribution and carbon matrix adsorption capacity, this product extends the effective adsorption duration per cycle compared to standard CMS grades. The raw materials-high-activity coal tar combined with modified phenolic resin-are processed through staged temperature-controlled carbonization and activation that create a highly developed pore network with generous gas exchange capacity. The result is a CMS that maintains consistent oxygen saturation capacity over extended adsorption periods, with gradual attenuation during pressure cycling. The product's uniform pellet formation and well-developed internal pore channels ensure complete gas contact without localized premature saturation, and the desorption process is thorough, preventing residual oxygen buildup that could compromise subsequent cycle performance.

Applications for Long-Cycle Nitrogen Generation

The long adsorption carbon molecular sieve is specifically recommended for PSA systems designed with extended adsorption cycles and larger tower volumes. Primary applications include large-scale metal heat treatment production lines, long-term petroleum storage tank inerting, large grain storage pest prevention systems, new energy battery production lines, large chemical reactor isolation protection, large-scale food nitrogen flushing facilities, and complete air separation nitrogen generation systems. In each of these settings, the extended adsorption capability reduces the number of switching cycles per day, which reduces valve wear, lowers energy consumption from frequent pressure changes, and extends the service life of system components. The product's stable performance over extended cycles also contributes to more consistent nitrogen purity and flow rate.

Guangde Yuanhao Molecular Sieve Co., Ltd. maintains an independent R&D laboratory with dedicated carbonization research furnaces and precision analytical testing instruments. This enables the company to independently complete comprehensive product testing including pore size analysis, adsorption capacity measurement, strength testing, and ash content determination. The company holds multiple invention patents in molecular sieve preparation and operates fully controlled production lines including energy-efficient ball mills, continuous carbonization furnaces, and extrusion equipment. Current production capacity is 150 tons per month, with a planned 2027 expansion to 300 tons per month. All raw materials undergo incoming inspection, and finished products receive 100% inspection before shipment. Each batch includes a factory test report, and third-party inspections are accepted.
