    • 2050年達成淨零排放是近年來受到全世界矚目的環保議題。交通運輸方面是需要改善的目標之一。在短期的幾十年之內仍然有些交通工具使用內燃機作為動力來源。因此探索既能保持引擎性能，又對環境友好的可再生燃料顯得尤為重要。
    2-甲基呋喃是近期獲選為具有發展潛力替代性燃料之一。本研究將從生物精煉廠的平台分子糠醛作為原物料，進行催化轉移氫化而得2-甲基呋喃。催化轉移氫化指的是以有機化合物（如醇類）中的氫原子為氫源，透過合適的觸媒將反應物氫化。因為催化轉移加氫過程不直接使用氫氣，可以避免使用氫氣的運輸與儲存風險。
    本研究設計甲醇與異丙醇兩種氫源的催化轉移氫化，應用於糠醛產出2-甲基呋喃的製程。分別就兩個案例建立熱力學與動力學模型，設計與優化製程，以及進行技術-經濟分析與碳排放分析。本研究在內部報酬率15%的情形下，以異丙醇為氫源之案例所能獲得2-甲基呋喃的最低售價為每公斤3.09美金，在經濟方面能與其他製程競爭。此外該案例在製造過程中有較低的單位產品之碳排放量。因此該案例為本研究最具潛力的製程。

    Achieving net zero emissions by 2050 has emerged as a prominent environmental concern that has garnered global recognition in recent years. Transportation is also one of the sectors that needs improvement. In the near future, there are still a number of vehicles that rely on the internal combustion engine as their primary power source. Therefore, it is particularly important to explore renewable fuels that can maintain engine performance while also being environmentally friendly.
    2-Methylfuran has recently been selected as one of the alternative fuels with development potential. In this study, 2-methylfuran was obtained from the catalytic transfer hydrogenation of furfural, which is a platform chemical in a biorefinery. Catalytic transfer hydrogenation refers to the use of hydrogen atoms within organic compounds, such as alcohols, as a source of hydrogen. This process involves the hydrogenation of reactants using an appropriate catalyst. Because the catalytic transfer hydrogenation process does not directly use hydrogen, the risks associated with the transportation and storage of hydrogen can be avoided.
    In this study, the catalytic transfer hydrogenation of two hydrogen sources, methanol and isopropanol, was designed and applied to the process of producing 2-methylfuran from furfural. Establish thermodynamic and kinetic models, design and optimize the process, and conduct techno-economic analysis and carbon emission analysis for both cases. In this study, under the condition of a 15% internal rate of return, the minimum required selling price of 2-methylfuran obtained by using isopropanol as a hydrogen source is $ 3.09 USD/kg. It can compete with other processes in terms of economics. Besides, this case has lower carbon emissions per unit of product during the manufacturing process. Therefore, this case is the most promising process in this study.
