“…Similarly to the Pd/ZnO catalysts, the alloys are responsible for the high CO 2 selectivity and the metallic Pd is responsible for CO selectivity. The ratios of Pd and the second metal as well as the loadings on the support have significant effects on the catalyst activity [62,63].…”

“…Men et al [62] studied the methanol steam reforming performance of Pd-In/Al 2 O 3 catalysts with different Pd loadings and Pd/In ratios. The results show that the catalyst with 7.5 wt.% Pd and 10 wt.% In 2 O 3 has the overall best performance considering both the methanol conversion rate and the CO content in the reformate.…”

Abstract:Methanol steam reforming is a promising technology for producing hydrogen for onboard fuel cell applications. The methanol conversion rate and the contents of hydrogen, carbon monoxide and carbon dioxide in the reformate, significantly depend on the reforming catalyst. Copper-based catalysts and palladium-based catalysts can effectively convert methanol into hydrogen and carbon dioxide. Copper and palladium-based catalysts with different formulations and compositions have been thoroughly investigated in the literature. This work summarized the development of the two groups of catalysts for methanol steam reforming. Interactions between the activity components and the supports as well as the effects of different promoters were discussed. Compositional and morphological characteristics, along with the methanol steam reforming performances of different Cu/ZnO and Pd/ZnO catalysts promoted by Al 2 O 3 , CeO 2 , ZrO 2 or other metal oxides, were reviewed and compared. Moreover, the reaction mechanism of methanol steam reforming over the copper based and palladium based catalysts were discussed.

“…Further studies [17,19] illuminated that CO 2 selectivity strongly depended on the particle size and the subsurface layers of PdZn alloy. Lately, Pd-Ga 2 O 3 [21] and Pd-In 2 O 3 [23] catalysts have also attracted much attention. Although Cu-based and Pd-based catalysts show good activity and selectivity to low temperature steam reforming, there are some obvious drawbacks.…”

“…Relevant experimental studies have been also performed for noble metal catalysts, mainly palladium and platinum supported on zinc, indium and gallium oxides. [30][31][32][33][34][35][36][37][38][39][40][41][42][43][44][45] Unlike methanol synthesis, which is also carried out on similar catalysts and temperatures, SRM process is not limited by thermodynamic constraints at low temperatures. Thermodynamic restrictions play a lesser role in SRM, as the inverse of methanol synthesis, steam reforming and decomposition reactions can be considered irreversible at atmospheric pressure.…”

Investigation of the Inhibiting Role of Hydrogen in the Steam Reforming of Methanol

et al. 2019

Steam reforming of methanol (SRM) was investigated over palladium zinc oxide catalyst modified with chromium, copper supported on alumina modified manganese oxide and commercial copper catalyst supported on zinc oxide modified with alumina. These catalysts showed high activity and selectivity towards hydrogen and carbon dioxide at low reaction temperatures. Temperature‐programmed desorption, diffuse reflectance infrared Fourier‐transform spectroscopy and catalytic performance studies, indicated that the presence of hydrogen in the gas stream influenced the course of SRM reaction. Such effects were related to hydrogen concentration over the catalysts, the reaction temperature and also the type of catalyst. Semi‐kinetic catalytic studies evidenced that an increase in hydrogen concentration in gas stream led to the decrease of methanol conversion at low‐reaction temperatures and decrease of selectivity to CO2 at high reaction temperatures. It was pointed out that strong interactions of hydrogen with the surface of catalysts may retard transformation of surface species into the SRM products.
