| Abstract |
This article focuses on the possible applications of multi-walled carbon nanotube (MWCNT) in CO_2 capture and adsorption cooling applications. In this study, surface properties namely surface area and... porosity of MWCNT are assessed employing N2 adsorption/desorption method. It is observed that surface area and total pore volume of MWCNT are about 640 m^2 g^<-1> and 1.151 cm^3 g^<-1>, respectively. Moreover, adsorption isotherms of CO_2 onto MWCNT are investigated at temperature ranging from 30 to 70 °C and pressures up to 5000 kPa. Experimental adsorption uptake data are fitted with well-known Tóth and modified Dubinin-Astakhov (D-A) adsorption models. Adsorption characteristic analysis reveals that 1 gram MWCNT can adsorb up to 0.631cm^3 amount of CO_2.show more
