分离氧化亚氮和二氧化碳的变压吸附方法研究

Study on the PSA Separation Method of Nitrous Oxide and Carbon Dioxide

介绍了使用变压吸附方法分离氧化亚氮和二氧化碳的实验研究,使用自制的改性吸附剂TK-103,在0.2MPa的吸附压力下,可将实验配制的含N_2O混合气中的CO_2脱除至20×10-6以下,且净化气中的N_2O收率达到约80%,该方法具有操作压力低、CO_2脱除精度高、N_2O回收率高、设备投资低及操作能耗省的优点,特别适用于从己二酸尾气中回收提纯氧化亚氮。

Introduce an experimental study on the separation of nitrous oxide and carbon dioxide by pressure swing adsorption,prepare a gas mixture which containing N2O,CO2and N2,with self-made modified adsorbent TK-103,and adsorption pressure is 0. 2 MPa,CO2 can be removed to lower than 20 × 10^-6 from the gas mixture,and the yield of N2O in purified gas reaches about 80%,the advantages of this PSA method are： low operating pressure,high removal precision of CO2,high yield of N2O,low equipment investment and low energy consumption,it＇s particularly applicable to recover and purify N2O from tail gas of adipic acid.
