摘要
本文考察了添加铁物类对炭分子筛空分性能的影响,实验表明添加铁物类能提高炭分子筛的空分能力。初步认为这是由于在顺磁性的Fe_3O_4产生的磁场的作用下,顺磁性的O_2被Fe_3O_4吸附于表面的缘故。
Effects of iron species added into carbon molecuar sieves (CMS) on the properties of the CMS are discussed. The air seperation ability of the CMS is improved when the iron species is added into the CMS, which is believed elementally that under the function of the magnetic field caused by Fe_3O_4, paramagnetic oxygen is adsorbed preferably by the CMS.
