Steam reforming of dimethoxymethane to hydrogen-rich gas over bifunctional CuO-ZnO/ƞ-Al₂O₃ catalyst-coated FeCrAl wire mesh

Catalytic steam reforming of dimethoxymethane (DMM) to hydrogen-rich gas was successfully performed using structured CuO-ZnO/ƞ-Al₂O₃/FeCrAl catalysts. The catalysts containing on their surface both acidic and copper-based sites were active and selective for DMM steam reforming to hydrogen-rich gas with low (< 1 vol.%) CO content. In particular, the CuO-ZnO/ƞ-Al₂O₃/FeCrAl catalysts provided a 100% DMM conversion with hydrogen production rate of ∼2500 ml H₂/(g_cat·h) at 300 °C, WHSV =3500 ml/(g_cat·h) and molar ratio H₂O/DMM = 4.5.
