dc.description.abstractAs a matter of fact, there is more and more carbon dioxide being released into atmosphere nowadays and a methodology is needed to reduce the amount of carbon dioxide for cleaner energy. Therefore, a study of physical gas adsorption of carbon dioxide with activated carbon (Maxsorb-III) and zeolite was carried out to measure experimentally the amount of CO2 uptakes and these data are fitted with different isotherms models. The adsorption efficiency of both materials are compared. In this project Scanning Electron Microscopy (SEM) and Transmission Electron Microscopy (TEM) were used to analyze the material structures and features of the porous adsorbent to study their material properties. Meanwhile, the volume of each cylinders and pipes, resistance temperature detectors and pressure transducers were calibrated to increase the precision of data collection of these instruments. The operating procedures will be discussed in one of the chapters. The adsorption experiment was conducted from 278.15 K to 328.15 K up to pressure of 30 bar for Maxsorb III and 20 bar for zeolite due to different adsorption properties, in order to study their equilibrium uptake rate. The measurement of adsorbate upake using CO2 properties from REFPROF databank provides the best accuracy. By varying pressure at certain temperature, the experimentally measured uptake data were used to fit with standardized IUPAC type I isotherm curves such as Langmuir, Dubinin-Astakhov (D-A) and Toth isotherms. The working procedures for fitting these isotherms are also discussed in this report.en_US
