Zeolite catalyst, there is a new molecular sieve (certified), there is a new zeolite molecular sieves by Shanghai Limited. Shanghai new molecular sieve Limited (www.molsionms.com) is specialized in the "sieve" of the enterprise, the company of "honesty, hard service" concept, to provide you with the highest quality products and services. Welcome to inquire! Contact: Mr. Pan. Carbon molecular sieve carbon molecular sieve is editing the 1970s developed a new type of molecular sieve adsorbent 3a manufacturers, is an excellent non-polar carbon molecular sieve material, nitrogen carbon molecular sieve (Carbon Molecular Sieves, CMS) used to separate nitrogen enriched air, at room temperature using low-pressure nitrogen process than conventional high-pressure nitrogen cryogenic process has less investment costs, faster production of nitrogen, nitrogen, and low cost. Therefore, it is the engineering preferred pressure swing adsorption (referred to as PSA) nitrogen-enriched air separation adsorbents, 3, equalizing time carbon molecular sieve nitrogen process, when the end of an adsorption column adsorption, the adsorption tower can have this pressure gas injection from both directions up and down the other had been regenerated adsorption tower made of carbon molecular sieve, and the same two towers gas pressure, this process is called adsorption towers equalizing, select the appropriate grading time, you can recycle energy, but also can slow molecular sieve adsorption tower have been hit, so as to prolong the service life of carbon molecular sieve. Reference switching speed cutting doors are usually selected pressure for 1 to 3 seconds.
