Abstract
Preparation and Characterisation of Blend Cellulose Acetate Membrane for CO2/N2 Separation
Highlights
Membrane technology is one of the gas separation methods that can effectively reduce the carbon dioxide (CO2) emission.[1,2] It has advantages such as being high energy efficiency, cheap, environmentally-friendly and simplicity.[3,4] SinceCO2 are mostly emitted from power generation plant, the CO2/nitrogen (N2) separation should be more effective to reduce the CO2 emission rate.[5,6] Based on Feron et al, the cellulose acetate (CA) holds the greatest promise in membrane material selection because it has the highest CO2/N2 selectivity compared with other polymeric materials.[7]
The CA membranes were blended at different polymer ratios of CA-39 and CA-56
New membranes were successfully fabricated by blending the CA-39 and CA-56
Summary
Membrane technology is one of the gas separation methods that can effectively reduce the carbon dioxide (CO2) emission.[1,2] It has advantages such as being high energy efficiency, cheap, environmentally-friendly and simplicity.[3,4] SinceCO2 are mostly emitted from power generation plant, the CO2/nitrogen (N2) separation should be more effective to reduce the CO2 emission rate.[5,6] Based on Feron et al, the cellulose acetate (CA) holds the greatest promise in membrane material selection because it has the highest CO2/N2 selectivity compared with other polymeric materials.[7]. CA has many advantages such as being low cost and environmentally friendly, which causes CA to be more preferable compared to the other polymeric materials.[8,9] There are two types of CA polymers used in this study, which are CA with acetyl content of 56% (CA-56) and CA with acetyl content of 39% (CA-39)
