Permselectivity of a PA6 membrane for the separation of a compressed CO_2/H_2 gas mixture at elevated pressures

摘要

Since rencently, compressed gases can substitute for harzardous solvents in the chemical industry. To meet economic and ecolgical demands, the reuse of compressed gas has become very desirable. This creates the need to remove, in advance, unwanted components (e.g. unconverted H_2 from hydrogenation reactions). This study examines a gas permeation process to achieve the separation of CO_2/H-2 micture under high pressure.
