| 제목 | Ag+ - Chitosan ComplexMembranes for Propylene/Propane Separation |
| 초록 | We have prepared new water-swollen chitosan-Ag+ complex membranes and studied their permeation and separation behaviors for propylene and propane gases. The AgNO3 and water content in Ag+ - chitosan complex membrane were controlled by adjusting AgNO3 concentration of casting solution. The permeation properties of propylene and propane were investigated as a function of AgNO3 concentration, and various operation conditions. High permeability of above 17 barrer and high selectivity of above 170 could be obtained with the membranes prepared from 3M AgNO3 aqueous solution. Periodic regeneration with 3M solution confirmed these membranes could be very useful for the separation of propylene/propane and other olefin/paraffin separation. |
