“…After selecting the optimal reactor temperature, we performed a set of experiments to analyze the dependence of the methanol conversion and outlet mixture composition versus the W=F CH 3 OH (g.min/mmol) [17,18]. Molar methanol feeding rate F CH 3 OH (mmol/min) was calculated from equation:…”

“…The observed H 2 consumption should be then assigned only to the reduction of copper species on calcined support. TPR analysis of the calcined solids reveals several peaks which can be attributed to various copper species, reduced at different temperatures [8]. Indeed, 10%Cu presented three species of copper which are reduced at low temperatures.…”

Copper supported on calcined hydrotalcite catalysts were prepared using the memory effect of zinc-aluminium hydrotalcite. Zinc-aluminium was calcined at 400°C and dopped in a copper nitrate aqueous solution for surface hydrotalcite regeneration. The calcination at 500 C of the sample copper/zinc-aluminium (Cu/Zn-Al) (400) leads to an interesting copper mixed oxide supported on calcined hydrotalcite. The surface copper hydrotalcite regeneration was observed and the reconstruction of the layered structure influenced positively the interaction between copper species and the support. These catalysts present an interesting activity for hydrogen production by steam reforming of methanol.
“…Heat transfer happens via dividing walls from the chamber where the exothermic reaction (methane oxidation) is taking place to another chamber where the endothermic reaction (methane reforming) is carried out (Patel & Pant, 2007;Simakov & Sheintuch, 2009). Exothermic and endothermic reactions take place in different chambers, which are separated by heat conductive walls.…”

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
