Steam reforming of methanol over CuO/ZnO/CeO2/ZrO2/Al2O3 catalysts

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

“…ZnO is well-known to improve the dispersion of Cu and the reducibility of CuO [5,6]. In addition, the efficiency of Cubased catalysts can be promoted by ZrO 2 , CeO 2 [4,[12][13][14]. ZrO 2 can promote the SRM reaction and slightly reduce the concentration of CO [13].…”

“…In addition, the efficiency of Cubased catalysts can be promoted by ZrO 2 , CeO 2 [4,[12][13][14]. ZrO 2 can promote the SRM reaction and slightly reduce the concentration of CO [13]. CeO 2 can hinder the Cu sintering and enhance the thermal stability of catalysts [14].…”

“…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.…”

Methanol steam reforming over Cu/CeO2 catalysts: influence of zinc addition

“…The effects of CeO 2 and ZrO 2 on CuO-ZnO-Al 2 O 3 catalysts have been also studied. 10,11 Recently, a review about copper-based catalysts has been published. 12 The use of CeO 2 -based catalysts has shown a rapid increase in the last decade.…”

“…strong interaction between Al2O3 and CuO [11,15,16]. Highly reducing atmospheres is reported to cause a phase change in the catalyst structure that result in sintering.…”
