Hydrogen Production by Ethanol Steam Reforming Over Cu and Ni Catalysts Supported on ZrO₂ and Al₂O₃ Microspheres

Abstract

Ethanol reforming process to produce hydrogen rich-gas stream is performed using Cu/Ni catalyst supported on zirconia and alumina microspheres prepared by hydrolysis method. Theses catalysts were tested in a fixed-bed reactor system employing steam reforming of ethanol. The operating temperature was 550°C and water/ethanol feed ratio 3/1. Although all catalysts were very active for ethanol conversion and very selective towards the desired products, but that one supported on zirconia microspheres was produced slightly better results. The data reveal high activity of the Cu/Ni/ZrO2 catalyst for ethanol steam reforming and presented a good selectivity for H2.

Short Review: Cu Catalyst for Autothermal Reforming Methanol for Hydrogen Production

“…Conventional methods for hydrogen production are based on gasoline [29][30][31], natural gas [42][43][44], methanol [45,23,22,[46][47][48][49][50][51]52], ethanol [12,15,53,[54][55][56][57][58], and a renewable raw material [59][60][61][62][63].…”

Influence of preparation method on supported Cu–Ni alloys and their catalytic properties in high pressure CO hydrogenation

“…Cu-Ni alloys are widely used as catalysts in, for example, steam reforming, [1][2][3][4][5][6] dimethyl carbonate synthesis, [7][8][9] hydrodeoxygenation, [10][11][12] water gas shift, [13][14][15][16][17] CO 2 hydrogenation, 18,19 and CO hydrogenation. [20][21][22][23] The chemical and physical properties of Cu-Ni alloys as well as the catalytic properties of the alloys have been described extensively in the literature.…”

In Situ Observation of Cu–Ni Alloy Nanoparticle Formation by X‐Ray Diffraction, X‐Ray Absorption Spectroscopy, and Transmission Electron Microscopy: Influence of Cu/Ni Ratio

“…[26,27] The structure of Cu-Ni catalysts has been the topic of numerous studies. These catalysts have been prepared by using different preparation methods such as: impregnation, [18,25] coprecipitation, [28] microemulsion, [29] and sol-gel methods, [30] and have been supported on different high surface area materials such as SiO 2 , [18,25,31,32] Al 2 O 3 , [28,33,34] ZnO, [17] TiO 2 , [11,12,35] ZrO 2 , [36,37] CeO 2 , [38] zeolite, [33] and carbon nanotubes. [39] Moreover, the selectivity and/or the activity is reported to change significantly upon variation in the Cu/Ni ratio for reactions such as hydrocarbon hydrogenolysis, [14] steam reforming, [25] CO 2 hydrogenation, [40,41] CO hydrogenation, [17] and water-gas shift.…”
