[0002] Molecular sieve is a kind of porous silicate (aluminosilicate) material with regular pore structure including zeolite, also known as zeolite molecular sieve, with the ability of screening small molecules, and large molecules cannot pass through. Molecular sieve can be divided into natural and synthetic molecular sieve, wherein synthetic molecular sieve can also be divided into microporous, mesoporous and macroporous molecular sieve according to its size. The factors affecting the adsorption efficiency of molecular sieve include the process conditions in the nitrogen production process and the properties of the molecular sieve adsorbent. In the adsorption tower, the newly added molecular sieve is a particle with a certain particle size, which is worn and torn due to the impact of high-pressure gas and the continuous flow of gas during the pressurized nitrogen production process, resulting in different degrees of pulverization and subsidence of the molecular sieve.
