用气相碳沉积法对炭分子筛进行了改性,并对吸附阶段温度、裂解温度、堵孔剂分压等改性条件予以详细考察;采用称量法在真空电子天平上评价了改性炭分子筛上乙烯和氧气的吸附扩散性能。结果表明,改性后炭分子筛选择吸附氧气的能力大大提高,可作为直接脱除乙烯中少量氧气的吸附剂。对扩散曲线模拟计算,拟合良好。 The carbon molecular sieve was modified by vapor phase carbon deposition, and the modification conditions of temperature, pyrolysis temperature and partial pressure of plugging agent were investigated in detail. The modified carbon molecular sieve On ethylene and oxygen adsorption and diffusion properties. The results show that the modified carbon molecular sieve can greatly enhance the ability to select and adsorb oxygen and can be used as an adsorbent for directly removing a small amount of oxygen in ethylene. The diffusion curve simulation, fitting well.
