چکیده
Advanced catalytic materials able to catalyse more than one reaction efficiently are needed within the CO2 utilisation schemes benefit from end-products flexibility. In this study, combination of Ni and Ru (15 1 wt%, respectively) was tested in three reactions, i.e. dry reforming methane (DRM), reverse water–gas shift (RWGS) methanation. A stability experiment with cycle methanation-RWGS-DRM carried out. Outstanding revealed for hydrogenation reactions as regards DRM, coke formation started after 10 h on stream. Overall, research showcases that a multicomponent Ni-Ru/CeO2-Al2O3 catalyst is an unprecedent versatile system gas phase recycling. Beyond its excellent performance, our switchable allows fine control selectivity.

متن کاملLow-temperature water-gas shift reaction over Cu- and Ni-loaded cerium oxide catalysts
In this paper we report on the activity of Cuand Ni-containing cerium oxide catalysts for low-temperature water-gas shift (WGS). Bulk catalysts were prepared in nanocrystalline form by the urea co-precipitation–gelation method. Lanthanum dopant (10 at.%) was used as a structural stabilizer of ceria, while the content of Cu or Ni was in the range of 5–15 at.% (2–8 wt.%). At low metal loadings, C...

An experimental and kinetic modeling study on the Ni-catalyzed conversion of methane under oxidative and reforming conditions is presented. The numerical model is based on a surface reaction mechanism consisting of 52 elementary-step like reactions with 14 surface and six gas-phase species. Reactions for the conversion of methane with oxygen, steam, and CO2 as well as methanation, water-gas shi...
متن کاملNanostructured Au–CeO2 catalysts for low-temperature water–gas shift
The composite system of nanostructured gold and cerium oxide, with a gold loading 5–8 wt%, is reported in this work as a very good catalyst for low-temperature water–gas shift. Activity depends largely on the presence of nanosized ceria particles. Various techniques of preparation of an active catalyst are disscussed. The presence of gold is crucial for activity below 300 ◦C. A dramatic effect ...
متن کاملGold–ceria catalysts for low-temperature water-gas shift reaction
Nanostructured Au–ceria is a promising new catalyst for low-temperature water-gas shift (LTS). Preparation, characterization, and catalytic properties of this material are reported in this paper. Gold–ceria was prepared by deposition–precipitation (DP), coprecipitation (CP), and gelation methods. The gold loading was varied between 1 and 8.3 at.%, while lanthanum used as a dopant in ceria, was ...
