碳分子筛用于分离空气中的氮,是世界上一种新的空气制氮技术。 氮和氧都是非极性分子,两者的沸点接近分子动力学直径也接近,氮为(3.0(?)),氧为(2.8(?)),故两者的分离是困难的。 碳分子筛是一种新型、高效非极性吸附剂,它对氮氧的变压吸附分离可视为物理过 Carbon molecular sieve is used to separate the nitrogen in the air, which is a new technology of nitrogen production in the world. Nitrogen and oxygen are non-polar molecules, the boiling point of both close to the molecular dynamics diameter is also close, nitrogen (3.0 (?)), Oxygen (2.8 (?)), So the separation is difficult. Carbon molecular sieve is a new, highly efficient non-polar adsorbent, its nitrogen and oxygen pressure swing adsorption separation can be considered physical
