Hydrogen production by steam reforming of methanol in a micro-channel reactor coated with Cu/ZnO/ZrO2/Al2O3 catalyst

Review on Copper and Palladium Based Catalysts for Methanol Steam Reforming to Produce Hydrogen

“…It includes four steps to fulfill a catalysis cycle, which are the adsorption of methanol and water at the Cu/CeO2 interface, followed by the surface reaction and the oxygen reverse spillover (the migration of surface oxygen from CeO2 to Cu), and, finally, the regeneration of partially oxidized copper and oxygen vacancies. ZrO2 added to Cu/ZnO catalysts can also enhance the copper dispersion on the catalyst surface and thus lead to higher activity [33,34]. Moreover, the introduction of ZrO2 into Cu/ZnO improves the reducibility and stability of the catalysts [35].…”

Experimental study and mechanistic kinetic modeling for selective production of hydrogen via catalytic steam reforming of methanol

“…On the other hand, SRM can produce H 2 /CO 2 in the molar ratio of 3 1 . The reaction occurs at low temperatures in the range between 473 and 573 K over Cubased catalysts (Busca et al, 2006;Jeong et al, 2006;Patel and Pant,2006b;Yang and Liao, 2007); its products are mainly hydrogen and carbon dioxide with a small amount of CO, usually less than 1%, as a by-product (Agrell et al, 2001;Purnama et al, 2004). For the design and control of reformer for SRM process, kinetic parameters are very useful.…”

Steam reforming of methanol over Cu/ZnO/ZrO2/Al2O3 catalyst

“…First, ZrO 2 added to Cu/Zn-based catalysts enhances D Cu and forms small copper particles on the catalyst surface [19]. Second, ZrO 2 can lower the Al content on the catalyst surface and weaken the interaction between CuO and Al 2 O 3 to avoid the generation of CuAl 2 O 4 spinel-type compound [30].…”
