Strength and wear are a bit poor. Keep working hard
Thank you, the friend from above. Could you be more specific?
The various oxygen-generation molecular sieves produced by our company have performance levels that are not much different from those of imported oxygen-generation molecular sieves, in terms such as nitrogen adsorption and separation coefficients. Those interested can discuss this further!

Thank you! May I ask your company what the nitrogen-oxygen separation coefficient of your oxygen-producing molecular sieve is under standard conditions?
Why not? It is through communication that there is improvement! !
N2 and O2 adsorption capacity； N2/O2 separation coefficient ； Strength ； Wear rate: For users of oxygen molecular sieves, the separation coefficient is a matter of great concern; I believe this value can only be used as a reference. It cannot be used as a key indicator to determine the quality of PSA oxygen-generation molecular sieves. After all, the PSA process is a dynamic process of adsorption under pressure. Both the adsorption capacity and the separation coefficient are static parameters, and there is no deterministic inherent relationship between them. What we need to focus on are gas production rate and air consumption. Compared to Ceca, its strength and wear resistance are lower
That makes sense! ! However, under the same PSA process conditions, using different molecular sieves will inevitably result in differences in energy consumption for producing oxygen on an industrial scale, right?
Yes, this is inevitable. However, when the static parameters are the same, the dynamic parameters for oxygen production can vary significantly among molecular sieves from different manufacturers
Well…… I have compared several lithium sieves; as the adsorption temperature increases, the nitrogen-oxygen separation coefficient gradually decreases, and the degree of this decrease is more or less the same across all of them.
