在此研究中，會將Pt負載於氧化鋁球上作為床材當中的催化劑，並在預熱溫度150-300℃、氧氣/二甲醚(O2/DME)莫爾比0.75-0.9 和流速 U/Umf=4~7之操作條件下研究二甲醚催化部分氧化之產氫效率，再以克里金模型進行數據之統計分析；從實驗結果可以發現 O2/DME 之比例越高將會促進氫氣與一氧化碳之產率，在O2/DME=0.9、流速 U/Umf=4~7和啟動溫度300℃之條件下可以達到最佳氫氣產率，DME之碳轉化率為100%，除此之外克里金模型中的θ係數是用以量化實驗參數影響實驗結果的能力，經過計算得知影響能力之排名為U/Umf > O2/DME > 啟動溫度，總結來說，隨著氧氣的莫爾分率提高將會促進二甲醚之深度氧化(Deep oxidation)進而讓轉化率、氫氣與一氧化碳之產率提升，另外透過克里金模型進行數據分析也可瞭解到在三個實驗參數中流速對於實驗結果之影響力最大，因為流速代表著滯留時間之長短，當 DME 在反應器當中之滯留時間越長將會使部分氧化的放熱反應產生更多熱量，使其達到更高之轉化率 。

Catalytic partial oxidation (CPOX) of dimethyl ether (DME) using a Pt-based catalyst for hydrogen production has been studied under O2/DME of 0.75-0.9, start-up temperature of 150-300℃, and U/Umf of 4-7. In addition, the surrogate model established by the kriging method was used to understand the influence of each parameter on the hydrogen yield. It suggests that the yield of hydrogen and carbon monoxide increase as O2/DME increases. Meanwhile, the optimal combination of operating conditions is analyzed with the Kriging model and validated by the experiment. In the optimal case(O2/DME=0.9, start-up temperature=300℃, and U/Umf=4), the carbon conversion rate of DME was 100%, and the yields of hydrogen and carbon monoxide were 67.58% and 79.94%, respectively. In addition, the value of θ in the kriging model is used to quantify the ability of each parameter to affect the experimental results. The θ value of start-up temperature, O2/DME, and U/Umf are 0.001, 0.2549, and 0.316, respectively. In summary, the deep oxidation of DME is promoted by the increase of the oxygen molar fraction, resulting in the increase of the conversion rate and the hydrogen yield. The U/Umf possesses the most influence on the yield of hydrogen because U/Umf presents the residence time of reactants in the fluidized bed. Longer residence times will promote exothermic reactions of CPOX and increase conversion.
