Kinetic Study Of Selective Sorption Of Co2 Using Composite Nanoparticles

Abstract

The demand for energy in the India, and across the globe, has been steadily increasing in recent years, and is projected to continue to increase for years to come. Simultaneously, concerns over the effects of global climate change, which is strongly a factor of atmospheric CO2 concentration, are also increasing. The purpose of CO2 capture is to produce a concentrated stream that can readily transported to a CO2 storage site. The main object of the project is to develop novel composite nanoparticles for selective CO2 sorption using novel citrate based sol-gel method. Also, it is the effect of dopping (Potassium and Sodium) on Li2ZrO3 is studied. The prepared nanoparticles is characterized using XRD, HR-TEM and TGA for sorption and capacity analysis. During the analysis it was found that the prepared Potassium doped Lithium Zirconate showed the highest rate of sorption at 625°C i.e. 20wt% in 30 mins. Where as Sodium doped Lithium Zirconate was found highest at 650°C i.e. 20w% in 30 mins. It was observed that surfactant chemistry has enhanced the property of prepared nanoparticles and also helps in controlling the morphology of sorbent.
