摘要:	隨著科技發展溫室效應造成全球暖化日益嚴重，而其中減少溫室氣體排放已成為重要議題。本研究分為兩部分，第一部分為台電綜合研究所之製備矽膠固著聚苯胺吸附劑及吸脫附試驗。探討矽膠固著聚苯胺之二氧化碳吸附劑合成的不同條件，並以造粒方法探討製備矽膠固著聚苯胺吸附劑的最佳條件。利用探討造粒前後合成溫度，合成時間，反應物濃度，矽膠固著聚苯胺之固態吸附劑能力等因素的影響，並藉由微量天秤Thermo Cahn D-200測量吸附量和吸附等溫線，並以一大氣壓下，以發電廠氣體比例15％二氧化碳及85％氮氣計算選擇率。再以台電綜合研究所之熱重分析儀測量觀察本研究矽膠固著聚苯胺吸附劑吸附力衰變測試，並對吸附劑性能的影響進行探討。本研究第二部分為氣化合成氣經富氧燃燒後之變壓吸附程序二氧化碳純化實驗。選用UOP 13X 沸石作為吸附劑，進料氣體為95%二氧化碳與5%氮氣。將吸附劑填入吸附塔進行突破曲線與脫附曲線實驗，藉由改變不同流量、溫度等探討突破曲線與脫附曲線的影響，進而以單塔四步驟變壓吸附程序純化二氧化碳，並探討如溫度、進料壓力、抽真空壓力、步驟時間等變因對其回收率、濃度的影響，研究最適化的操作條件，以獲得高純度二氧化碳。 ;With technology development, the greenhouse effect is becoming more and more serious. Reducing greenhouse gas emissions has become an important issue. The first part of the study is the experimental study of CO2 adsorption / desorption with Solid Polyaniline Sorbent of Taiwan Power Company (Taipower). Changing the different conditions for the synthesis of solid polyaniline carbon dioxide sorbent and the preparation of pelletization procedures obtains the optimal condition for producing solid polyaniline sorbent. The effects of different factors such as synthesis temperature, synthesis time, compound concentration and the adsorption capacity of solid polyaniline carbon dioxide sorbent before and after pelletization were discussed. Adsorption amount and adsorption isotherm were obtained by used Micro-Balance Thermo Cahn D-200 and selectivity of carbon dioxide with respect to nitrogen is calculated based on 15% CO2 / 85% N2 feed at 1 atm. The degree of adsorption amount decay of sorbent is obtained by using TGA of Taipower Research Institute. The second part of the study is the experimental study of concentrating high purity CO2 from syngas after oxy-fuel combustion by pressure swing adsorption process. UOP 13X zeolite was used as the adsorbent, and the feed gas was 95% CO2 / 5% N2. Breakthrough curves and desorption curves were discussed by changing the pressure and temperature. Next the carbon dioxide was purified by single-bed four steps pressure swing adsorption procedure. Variables such as temperature, feed pressure, vacuum pressure and step time were discussed to find their effects on CO2 recovery and purity in order to study the optimal operating conditions for obtaining high purity carbon dioxide.
