Methanol synthesis from CO2 hydrogenation over Cu based catalyst supported on zirconia modified γ-Al2O3

Catalytic Hydrogenation of CO2 to Methanol: Study of Synergistic Effect on Adsorption Properties of CO2 and H2 in CuO/ZnO/ZrO2 System

“…were adopted, and the positive effects of them have also been documented [15][16][17][18][19][20][21][22][23][24][25][26]. Additionally, the composition, texture of catalysts, and dispersion of metal and oxide phases on the catalysts are also greatly associated with their activities, which can be obtained using a variety of preparation methods [16,23,[27][28][29][30][31] Arena et al [16,21,28,32] used reverse co-precipitation under ultrasound irradiation to obtain a series of Cu-ZnO/ZrO2 catalysts with a remarkable total surface area and high dispersion. Deng et al [7,12] and Bonura et al [32] adopted the oxalate-co-precipitated technique to enhance the catalyst activity, whereas Guo et al [29,33] found that the combustion method was a simple, fast, and valuable route.…”

Catalytic Performance of Cu/ZnO/A12O3/ZrO2 for Slurry Methanol Synthesis from CO2 Hydrogenation: Effect of Cu/Zn Molar Ratio

“…At present the conventional CZA catalysts exhibit poor activity for CO 2 hydrogenation, because of water formation and strong hydrophilic character of alumina (Arena et al 2007). Several authors have established that copper based catalysts containing zirconia are active in the synthesis of methanol from CO 2 and H 2 (Samson et al 2014;Ud Din et al 2016;Witoon et al 2016;Zhang et al 2006). Arena (2008) investigated the reaction of CO 2 hydrogenation in a fixed bed reactor on Cu-ZnO/ZrO 2 , (ZrO 2 loading, 43 wt.…”

“…However, the zirconia bears the disadvantages of low surface area and poor thermal stability compared to the alumina counterparts. Zhang et al (2006) addressed this issue by spreading the zirconia in supports with relative higher surface area, such as g-alumina. The effect of zirconia modification of g-Al 2 O 3 supported Cu catalyst was tested in a fixed-bed reactor at temperature of 240°C.…”

The effect of ageing time on co-precipitated Cu/ZnO/ZrO2 catalysts used in methanol synthesis from CO2 and H2

“…[4][5][6][7][8][9][10][11][12]. Copper based catalysts have been widely investigated in combination with various metal oxides such as Al 2 O 3 [4,5], Cr 2 O 3 [6], TiO 2 [4], ZnO [6,7] and ZrO 2 [8,9], and their combinations [5][6][7][10][11][12].…”

Several authors have established that copper based catalysts containing zirconia are active in the synthesis of methanol from CO 2 and H 2 [5,[11][12][13]. Sloczynski et al [11] investigated Cu, Ag and Au catalysts supported on 3ZnOAEZrO 2 in detail, and found that the Cu catalyst was by far the most active.…”
