Latest Patents

Chuin-Tih Yeh's latest patents include a groundbreaking process for hydrogen production that operates at lower temperatures. This process utilizes catalysts such as Mn/ZnO, Cu/MnO, Cu/CeO, CuCe/ZnO, and CuMn/ZnO. It allows for the partial oxidization of methanol (POM) to be initiated at ambient reactor temperatures below 100°C, with a reaction temperature maintained under 200°C. This innovative method not only produces hydrogen-rich gas (HRG) with less than 4% CO but also generates 1.8 moles of hydrogen or more for every mole of methanol consumed.

Another significant patent by Yeh describes a low-temperature reforming process for hydrogen production from methanol. This process achieves a high hydrogen yield at low temperatures by pre-mixing an aqueous methanol solution with oxygen. The mixture is then passed through an activated supported gold catalyst, resulting in a hydrogen-rich gas with CO content below 1% at reaction temperatures exceeding 150°C. The process can generate more than 2 moles of hydrogen for each mole of methanol consumed, showcasing Yeh's commitment to advancing hydrogen production technologies.
