Synthesis of PIL membranes for CO2 separation
Carbon dioxide (CO2) can be commonly found in natural gas streams, biogas, flue gas and product of coal gasification[1]. The presence of CO2 and other acid gases reduce the thermal efficiency and make the gas streams become acidic and corrosive, which in turn reduces the possibilities of gas compression and the transport within the transportation systems[2]. Membrane separation is a promising t...
متن کاملAlPO-18 membranes for CO2/CH4 separation.
The synthesis of reproducible and continuous AlPO-18 membranes is demonstrated. The separation performance of these membranes for equimolar CO(2)/CH(4) gas mixtures is presented. The AlPO-18 membranes displayed CO(2) permeances as high as ~6.6 × 10(-8) mol m(-2) s Pa with CO(2)/CH(4) separation selectivities in the ~52-60 range at 295 K and 138 kPa.
متن کاملSize Effects of Graphene Oxide on Mixed Matrix Membranes for CO2 Separation
Graphene oxide (GO)-polyether block amide (PEBA) mixed matrix membranes were fabricated and the effects of GO lateral size on membranes morphologies, microstructures, physicochemical properties, and gas separation performances were systematically investigated. By varying the GO lateral sizes (100–200 nm, 1–2 lm, and 5–10 lm), the polymer chains mobility, as well as the length of the gas channel...
متن کاملFunctionalized Polymeric Membranes for CO2 Capture
Reducing CO2 emission and lowering the concentration of greenhouse gases in the atmosphere has quickly become one of the most urgent environmental issues. While a variety of technologies and methods have been developed, the separation of CO2 from gas streams is still a critical issue. Apart from establishing new techniques, the exploration of membrane materials with high separation performance ...
