Abstract:	近年來由於溫室氣體引起的環境問題日益受到重視，溫室氣體減量變得勢不容緩。而溫室氣體中的二氧化碳排放最主要來自於工業上化石燃料的燃燒，因此如何純化及回收煙道氣中的二氧化碳便成為解決此問題的首要之務。本研究首先利用實驗的方式，使用微量天平(Micro-Balance Thermo D-200)量測PEI/SBA-15固態吸附劑對CO2飽和吸附量，以獲得等溫吸附平衡曲線(isotherm)。接著以單塔進行貫流曲線實驗，藉由改變不同的操作條件(如：塔內溫度、進料壓力及進料流速)，觀察其對貫流曲線的影響。最後本研究以電廠煙道氣的組成，利用變溫吸附程序進行操作變因的探討。模擬進料組成為15.03%CO2和84.97%N2的混合氣體，藉由改變不同的操作條件(如：進料壓力，吸附溫度，脫附溫度)，探討塔底產物二氧化碳濃度和回收率的變化，進而找出最佳操作條件。 ;In recent years, due to the environmental problems caused by greenhouse gases, reducing the emission of greenhouse gases has become urgent. CO2 released into the atmosphere are mainly attributed to fossil fuel combustion, so that the purification and recovery of CO2 from flue gas is the first important step in solving CO2 problem. This study obtained single component adsorption equilibrium data of CO2 on PEI/SBA-15 solid sorbent by using Micro-Balance Thermo D-200 and established the equilibrium isotherm. Then breakthrough curve experiments wereperformed with single bed by changing the different operating conditions (bed temperature, feed pressure, feed flow rate, etc) to observe their influence on breakthrough curve. Finally, we experimentally studied the use of temperature swing adsorption process in treating power plant flue gas. We used mixture gas which is composed of 15.03% CO2 and 84.97% N2 to investigate the change of outlet CO2 concentration and recovery by changing the different operating conditions (feed gas pressure, adsorption temperature, desorption temperature, etc), and then found the best operating conditions.
