作者以碳氟高分子聚合物为膜材，通过辐射接技技术，得到含氟核酸膜（PFCM），并分别用乙二胺（EDA）、三乙醇胺（TEA）、三乙烯二胺（TEDA）等三种活性载体，对PFCM进行改性，得到了酸性气体促进传质膜。它们具有优先渗透酸性组份的特征，可用于天然气净化。本文以CH4、CO2和H2S为对象，测定了上述几种膜内的吸收等温线数据和渗透动力学数据。分别考察了活性载体种类和改性度以及温度等参数对膜性能的影响。进而阐述了气体在该膜内的传质机理。
The fluorinated nucleic acid membrane (PFCM) was obtained by using the fluorocarbon polymers as the membrane material. The membranes were treated with ethylenediamine (EDA), triethanolamine (TEA), triethylenediamine (TEDA) And other three kinds of active carriers, the PFCM was modified to obtain acid gas to promote mass transfer membrane. They have the characteristic of preferential penetration of acidic components and can be used for natural gas purification. In this paper, the adsorption isotherms and permeation kinetics data of the above four kinds of membranes were measured with CH4, CO2 and H2S. The influence of the types of activated carriers, the degree of modification and temperature on the membrane properties were investigated. Then expounds the gas mass transfer mechanism in the membrane.
