Precautions for picking carbon molecular sieves
Precautions for picking carbon molecular sieves
Most manufacturers have no significant difference in the carbon molecular sieve in the outer shape, so the user is difficult to distinguish by observing the outer shape of the molecular sieve is difficult to distinguish between imported molecular sieves or domestic molecular sieves. But one thing, if the manufacturer claims to use the high-quality imported molecular sieve, but the price is much lower than the market price, then be careful. It is impossible to sell the equipment without selling the fine. Equipment to buy an in-house domestic molecular sieve is not terrible, but the price of imported molecular sieves has bought domestic molecular sieves, and that loss can be big.
We know that using carbon molecular sieve pressure adsorption nitrogen is separated from Van Dehua to separate oxygen and nitrogen, the larger the specific surface area of the molecular sieve, the more uniform the aperture distribution, the more micropores or submicropiles, the amount of adsorption The bigger the more; at the same time, if the aperture can be as small as possible, Van Dehua's field overlaps, there is a better separation of low concentration substances. Therefore, in the PSA nitrogen nitrogen apparatus, the performance of the molecular sieve is directly related to the gas content and energy consumption of the entire device, so that the appropriate adsorbent is the weight.
