Highly selective supported Pd catalysts for steam reforming of methanol

High-temperature steam reforming of methanol over ZnO–Al2O3 catalysts

“…Low temperature steam reforming mainly focuses on Cu-based [3][4][5][6][7][8][9][10][11][12][13][14][15] and Pd-based [16][17][18][19][20][21][22] catalysts. For Cu-based catalysts, the most extensively studied catalysts are Cu/ZnO and Cu/ZnO/Al 2 O 3 [7,9,10], etc.…”

“…CeO 2 can hinder the Cu sintering and enhance the thermal stability of catalysts [14]. Apart from Cu-based catalyst, Pd-based catalyst is another promising low temperature steam reforming catalyst [16][17][18][19][20][21][22]. Iwasa et al [20] first found Pd/ZnO had good activity, CO 2 selectivity and thermal stability for low temperature steam reforming of methanol, and all these were attributed to the formation of PdZn alloy.…”

Iwasa et al [20] first found Pd/ZnO had good activity, CO 2 selectivity and thermal stability for low temperature steam reforming of methanol, and all these were attributed to the formation of PdZn alloy. Further studies [17,19] illuminated that CO 2 selectivity strongly depended on the particle size and the subsurface layers of PdZn alloy.…”

Preparation of Palladium Catalysts by Pretreatment Steps in Electroless Plating toward Partial Oxidation of Methanol with Steam Reforming

“…An impregnation method has been performed by the addition of supports into precursor suspensions of metal catalysts. 11,12 In a precipitation method, the PdZnO catalysts were prepared by the addition of a basic solution to a mixed aqueous solution of Pd and Zn salts. 13 PdZnO catalysts have also been prepared by heat treatment of physical mixtures of Pd and Zn powders.…”

Modeling of a compact plate-fin reformer for methanol steam reforming in fuel cell systems

“…Steam reforming of methanol reaction has been a highly developed and thoroughly studied process [2][3][4][5][6][7][8]. It can offer the highest maximum hydrogen content in the product gas (75%) while maintaining a high selectivity towards carbon dioxide.…”
