    摘要： The gas separation and purification process can recover efficiently a valuable gas such as krypton and xenon to be used as an atmospheric gas in a semiconductor manufacturing equipment etc. by means of PSA process. In the process for separating a valuable gas in the form of purified product from a mixed gas, used as a raw gas, containing the valuable gas by means of pressure swing adsorption process, the valuable gas is separated and purified by using as the pressure swing adsorption process a combination of equilibrium pressure swing adsorption process for separating gas components based on the difference in equilibrium adsorption and rate-dependent pressure swing adsorption process for separating the gas components based on the difference in adsorption rates.

    摘要： CMS adsorbents having suitable indexes are used to improve greatly the performance of nitrogen-producing apparatuses where nitrogen is obtained from the air with a PSA method, so as to improve the efficiency of nitrogen production. A nitrogen PSA apparatus is formed with two adsorbing columns where an adsorption step and a regeneration step are performed alternatively and periodically. The adsorption step is for adsorbing oxygen and conducting nitrogen to a product tank with the supply of compressed air from an air compressor, and the regeneration step for releasing the adsorbed gas after the adsorption step. The adsorbing columns are filled with a carbon molecular sieve (CMS) that selectively adsorbs oxygen as an adsorbent. The CMS adsorbs an oxygen/nitrogen amount of 50% of the saturated adsorption amount with a period TO/TN starting from oxygen/nitrogen supply, wherein TO is 5˜10 seconds and TN is larger than TO by more than 41 times.
