Abstract
Carbon capture is essential for lowering anthropogenic carbon emissions and, as a result, limiting global warming. Membrane technology has a lot of potential for extremely efficient carbon capture because of its energy-efficient and environmentally friendly properties. This research focuses on the development of a clean carbon dioxide (CO2) capture technique based on a ceramic membrane. DAC (direct air carbon capture) is a new method of extracting CO2 from the atmosphere with the potential to remove massive amounts of CO2. This study presents experimental results on the permeation of gases such as carbon dioxide and air through ceramic membranes with pore size of 200nm and 6000nm at temperatures of 20°C, 100°C and 150°C. The behaviour of gases across the membrane was depicted in the experimental results, demonstrating that pressure is a major determining factor in determining the rate of flow for gases through the membrane, as the flow rate of both CO2 and air gases increased exponentially regardless of membrane geometry of operating conditions. Experimental results showed that the gas permeance of CO2, Air, through a ceramic membrane with different pore sizes of 200nm, 6000nm, decreases with increasing pressure drop. It interested to note for ceramic membranes, with different pore sizes (200nm, 6000nm) the permeance of Air is larger than that of CO2. This indicated that CO2 can be adsorbed by ceramic membranes. The ceramic membrane's inner surface morphology was studied. The particles are equally scattered across the ceramic membrane's surface. The ceramic membrane's surface is crack-free and smooth, contact angle measurements were also used for ceramic membrane characterization. The ceramic membrane's water contact angle is 43.54 degrees, indicating that it has a hydrophilic surface. This is due to the presence of hydroxyl (OH-) groups having hydrophilic properties on their surface and pores.
