Study of methanol steam reforming and ethanol conversion in conventional and membrane reactors

Аннотация

Research results for methanol steam reforming and ethanol conversion in a conventional and a membrane reactor in the presence of Ru–Rh/DND, LiZr₂(PO₄)₃, and Li_1.1Zr_1.9In_0.1(PO₄)₃ catalysts have been described. The samples have been characterized by X-ray diffraction, scanning electron microscopy, and the BET method. The study of the catalytic properties of the catalyst composites has shown that the Ru–Rh/DND catalyst mostly mediates the dehydrogenation process, while LiZr₂(PO₄)₃ and Li_1.1Zr_1.9In_0.1(PO₄)₃ exhibit activity in both the dehydration and dehydrogenation reactions. The membrane process with a Pd–Ru alloy membrane provides a 20% increase in the hydrogen yield.
