dc.description.abstract本研究為測試並評估二氧化碳吸附劑之性能,選用的吸附劑為UOP 13X zeolite以及工研院PEI/SBA-15 solid adsorbent、X-type zeolite fiber、amine-grafted fiber和台電綜合研究所製備之solid polyaniline CO2 adsorbent,藉由微量天平實驗測試其等溫平衡吸附曲線,獲得在不同壓力下之氣體吸附量,作為吸附劑的選擇依據。 本研究以經水煤氣轉化後之合成氣作為變壓吸附分離程序實驗之進料氣體 (模擬為41.4 % CO2和58.6 % N2),選用UOP 13X zeolite進行微量天平等溫平衡吸附實驗,測得高溫時二氧化碳與氮氣在不同壓力下的吸附量,再將其填入單塔中以進行貫流曲線實驗與脫附曲線實驗。藉由改變不同壓力與溫度來探討貫流曲線與脫附曲線之變化,以作為變壓吸附分離程序實驗之基礎探討。 接續進行單塔四步驟變壓吸附分離程序實驗進行二氧化碳的濃縮與純化,藉由改變程序步驟時間與塔內溫度之操作變因來分析二氧化碳濃度與回收率,從而找到最佳操作條件,期望能作為未來放大規模製程之參考。zh_TW
dc.description.abstractIn this study, we intended to test and evaluate the performance of CO2 adsorbent. The adsorbents in the study include UOP 13X zeolite and ITRI PEI/SBA-15 solid adsorbent, X-type zeolite fiber, amine-grafted fiber, and solid polyaniline CO2 adsorbents provided by the Taiwan Power Research Institute. By microbalance experiments, we can measure their isothermal equilibrium adsorption curve of the gas adsorption capacity under different pressure. We hope these evaluations can provide selection basis for CO2 adsorption process. The main subject of the present study is to use the syngas after water-gas-shift reactor as feed gas (simulated as 41.4 % CO2和58.6 % N2) of pressure swing adsorption process. We chose UOP 13X zeolite as the adsorbent to measure the adsorption capacity of CO2 and N2 under different pressures with microbalance isothermal equilibrium adsorption experiments. Breakthrough curve experiments and desorption curve experiments were performed by changing different pressure and temperature to investigate changes in the breakthrough curve and desorption curve. These experimental results could be the basis of investigating pressure swing adsorption separation process. A single-bed four-step pressure swing adsorption process was applied to concentrate and recover CO2. We evaluated the purity and recovery of CO2 and N2 by changing the step time and the operating temperature of the column. At the end, the optimal operating condition was found and we expect that it can be a reference for the scale-up process.en_US
