Oxygen/Nitrogen Separation using Asymmetric Carbon Membrane
Nowadays, separation of oxygen and nitrogen is of a great importance, as it has been subjected in many industrial applications. Currently, there are three technologies that exist to fulfill this task i.e., cryogenic distillation, pressure swing adsorption (PSA), and membranes. The vast majority of membrane technologies share the common advantages of energy conservation and are proven to have a low environmental impact. In this study, thepreparation of asymmetric carbon membranes was achieved using a simple sucrose, C12H22O11, as carbon precursor. The sucrose precursor was converted to a carbon matrix at (300-500oC). These carbon membranes exhibit a separation performance with O2/N2 selectivity of 2.04 and O2 permeability of 87.33GPU.
