Zeolite molecular sieve 13X-APG-V is also a crystalline aluminosilicate, the sodium form of type X zeolite, featuring a uniform pore opening of approximately 10 angstroms (1.0 nm). 13X-APG-V represents the fifth-generation of 13X molecular sieve, and latest evolution of the 13X-APG product family. 13X-APG-V molecular sieve is innovatively developed for the air prepurification unit of cryogenic air separation plants.
Through continuous optimization of crystal structure, pore distribution, binder formulation, and manufacturing technology, type 13X-APG-V molecular sieve delivers substantially enhanced adsorption performance and operational reliability compared with previous generations. The dynamic adsorption capacity of 13X-APG-V is more than twice that of conventional 13X-APG, and over 1.4 times higher than that of 13X-APG-III, significantly extending adsorption cycles while reducing regeneration frequency and overall operating costs.
Compared with earlier generations, 13X-APG-V molecular sieve offers faster adsorption kinetics, greater equilibrium adsorption capacity, improved mass transfer efficiency, superior mechanical strength, lower attrition rate, and excellent resistance to repeated adsorption-regeneration cycles. These characteristics enable the molecular sieve to maintain high adsorption efficiency under demanding industrial conditions, including high air throughput, frequent pressure swing operation, and long-term thermal regeneration.
13X-APG-V molecular sieve has established a new benchmark for cryogenic air separation adsorbents. It is widely applied in large and ultra-large air separation units for the production of oxygen, nitrogen, argon, and other industrial gases. Practically, it is applicable for cryogenic air separation projects with a processing capacity of 60,000 Nm3/h and above, or for upgrading existing plants to improve efficiency.
