中文摘要 再生觸媒技術在氫化柴油製程中扮演重要的角色,活化效用和經濟性被綜合考量,本研究探討一種新興相當具潛能的再生技術:超臨界二氧化碳萃取技術,透過實驗分析二氧化碳在近臨界帶區域的溶劑能力、共溶劑種類/濃度與操作的方式對於再生效用的影響,確定了以批次式、76 bar、523 K、添加6 wt%正己烷作為共溶劑的最佳化參數再生失活的商用硫化NiMo/γ-Al2O3觸媒,得到質量移除率達15.46 %的結果。再生後的觸媒特性使用XRD、TGA、Py-FTIR和氮氣等溫吸附/脫附儀進行檢測與討論。另外,藉由既有的氫化柴油製程系統,研究新鮮、失活與再生後催化劑分別產出的氫化柴油,使用GC-MS/FID比較油品的轉化率與成分隨反應時間的變化趨勢。
英文摘要 Catalyst regeneration technology plays an important role in the chemical industry also the hydro-processed application in this study. Considering the effects of activation and economics, the regeneration process is inevitable and important. This research study on a rising and promising regeneration technology “supercritical carbon dioxide extraction technology”. Based on the experimental results, the solvent capacity of carbon dioxide in the near-critical zone, the categories/concentration of co-solvents, and the way of operation have been investigated for the effect of regeneration. The best mass removal rate of catalyst which means the best regeneration catalyst was obtained under the optimal reaction conditions of using batch operation, 76 bar, 523 K, 10 ml/per period Hexane as co-solvent, 1.5 hours each cycle and 2 or 3 cycles were recommended. The best mass removal rate of 15.46% of NiMo/γ-Al2O3 catalyst, which means the best regeneration catalyst was obtained under the optimal reaction conditions of using batch operation, 76 bar, 523 K, 10 ml/per period Hexane as co-solvent, 1.5 hours each cycle and 2 or 3 cycles were recommended. The characteristics of regenerated catalyst were tested and analyzed by XRD, TGA, Py-FTIR and Nitrogen adsorption/desorption isotherm. In addition, with the existing hydro-processed system, the difference and mechanism of hydro-processed renewable diesel produced from fresh, deactivated and regenerated catalysts was studied. The conversion rate of oil products and the trend of composition changes with reaction time were compared by GC-MS/FID.
