TEMPERATURE DEPENDENCE OF AIR SEPARATION OF LIQUID CRYSTALLINE TRIHEPTYL CELLULOSE/ETHYL CELLULOSE MEMBRANES

Center of Membrane Separation Engineering, Department of Textile Chemical Engineering, Tianjin Institute of Textile Science and Technology, Tianjin 300160

Triheptyl cellulose/ethyl cellulose (3/97) binary blend membranes were prepared from tetrahydrofuran, chloroform and dichloromethane solutions and their air separation capabitities were studied at different temperatures.With increasing temperature from 25 to 85℃, the flux Q_OEA of O₂-enriched air (OEA), O₂ permselectivity and the O₂ concentration Yo₂ in the OEA all increase.The membranes show a unique trend in their Yo₂~Q_OEA relationship, that is, the air separation capability increases simultaneously with the OEA permeation capability.The magnitudes of Q_OEA and Yo₂ for 17μm-thick membrane after the testing time of 36hours at 70℃ are 5×10cm³ (STP)/s·cm^-2 and 37.6%, respectively.The air separation capability depends slightly on membrane forming solvents.
