| dc.description.abstract | The separation effect of methane (CH4) and carbon dioxide (CO2) which is binary mixture of natural gas was investigated with characterization tests, breakthrough study and pressure swing adsorption (PSA) process. 2 types of adsorbent were studied and compared which were activated charcoal and zirconium-benzenedicarboxylate (UiO 66). The characterization tests showed that UiO-66 has higher BET surface area and activated charcoal has higher fixed carbon content. For breakthrough study, the breakthrough curves were obtained under the condition of 1 bar and room temperature. The effects of both adsorbents and different inlet gas ratio were investigated. UiO-66 has larger adsorption capacity proven by its longer breakthrough time. Besides, PSA process had utilized 2-bed adsorption under the conditions of 3 bar and room temperature. However, separation effect of this mixture was not effective and commercially attractive because 2 types of adsorbent used were not suitable for separating this binary gas. Hence, the purity was not achieved but the recovery could be obtained because UiO-66 showed more than 90% recovery on CO2. | en_US |
