Selective Permeation of CO_2 Through Modified PVSA/PS Composite Membrane

摘要

A new fixed carrier membrane material VSA-SA for CO2 separation was preparedthrough the chemical modification of PVSA. The selective permeation of CO2 throughVSA-SA/PS composite membrane was performed with CO2/CH4 system. The VSA-SA/PScomposite membranes possess better CO2 permselectivity than PVSA/PS composite membrane.
