Development of Novel Solid Sorbents for CO2 Capture/Separation

There are worldwide concerns due to CO2 emissions because of its adverse consequence on climatic fluctuations, extinction of species, and plant nutrition deterioration. The global average atmospheric CO2 was reported 409.8 and 420 parts per million (ppm) in 2019 and 2021 respectively. The level is expected to rise 550 ppm in 2050. Therefore, there is urgent need to address this impending issues and the development of technologies to lower CO2 emissions. The sole commercially mature technology to capture CO2 is an aminebased scrubbing, but its higher cost, equipment corrosion and harmful byproducts forces researchers to discover alternative new technologies. Currently, the adsorption separation has received a considerable attention as a viable alternative over absorption technology. The first and most essential step in this technology is to design and develop efficient sorbent/s for CO2 capture. The use of appropriate sorbents may potentially reduce the cost associated with CO2 separation in the overall carbon capture strategy. Therefore, the aim of this project is to develop potential class of sorbent materials (such as MOFs, Zeolites and Activated carbon) for CO2 adsorption. The sorbents possessing higher CO2 affinity will be selected and synthesized. The resultant material will be further activated or modified by decorating CO2 affinity group to enhance CO2 capture capacity. The developed materials will be characterized by relevant characterization techniques and evaluated for CO2 adsorption kinetics at different temperature (0, 25 and 40 C) and 1 bar of pressure from flue gas. The newly developed CO2 sorbents might contribute to carbon capture technology which leads to the mission of carbon neutral society. The industries (such as SABIC and S. Aramco) in the Kingdom could be targeted as end user as they may utilize these sorbent materials for various commercial applications
