The incorporation of graphene oxide into polysulfone mixed matrix membrane for CO2/CH4 separation
Carbon dioxide (CO2) is often found as the main impurity in natural gas, where methane (CH4) is the major component. The presence of CO2 in natural gas leads to several problems such as reducing the energy content of natural gas and cause pipeline corrosion. Thus it must be removed to meet specifica...
