Development of a transition metal based catalyst aiming at concomitant high activity and stability attributed to distinguished catalytic characteristics is considered as the bottleneck for dry reforming methane (DRM). This work highlights role modifying zirconia (ZrO2) alumina (Al2O3) supported nickel catalysts using lanthanum oxide (La2O3) varying from 0 20 wt% during methane. The mesoporous w...

Bond-Order Conservation-Morse Potential (BOC-MP) method is used to carry out the calculationon the CO2+ H20 system. One of the best catalysts for methanol synthesis in catalytic reductionof CO2 with H2O is Cu/ZnO/A1203 whose surface is supported by with some amount of Pd orGa. Reduction of CO2 with H20 on Cu will result in methanol formation; while on Ni will lead tomethane formation. In the me...

Ni/Al2O3, Co/Al2O3 and bimetallic Ni(Co)/Al2O3 catalysts were prepared using an impregnation method and employed in CO2 dry reforming of methane under coking-favored conditions. The spent catalysts were carefully characterized using typical characterization technologies and inelastic neutron scattering spectroscopy. The bimetallic catalyst exhibited a superior activity and anti-coking performan...

Because of their various potential applications, non-porous, selective oxygen permeable ceramic membranes with mixed ionic and electronic conductivity (MIECs) have received significant interest over the past decade [1-8]. In particular, the incorporation of these materials into catalytic reactors for the oxidation of hydrocarbons is being investigated as a way to eliminate costly air separation...

Biogas is one of the main biomass-energy resources. Its use for syngas production with a H2/CO ratio close to 2 would have huge environmental, social and economic impact in the actual energetic scenario. However, the use of dry reforming, where the two main components are transformed into syngas, does not allow the desired H2/CO ratio. For this reason, the addition of water is proposed. The pro...

the global temperature has increased over the past years, and international community attempt to reduce greenhouse emissions to the atmosphere. in this study the potential of some agriculture sections for emission and absorption of co2 and ch4 was examined. rice and wheat which are two strategic crops in iran were selected for this purpose and the amounts of organic carbon loss in the form of c...

Catalyst community requires a low-cost, high-performance catalyst immediately for cost-effective H2 production through dry reforming of methane. Herein, 1–9 wt% tungsten oxide-alumina supported Ni catalysts were prepared, examined and characterized by x-ray diffraction, 27Al solid-state nuclear magnetic resonance, X-ray photoelectron spectroscopy, high resolution-transmission electron microscop...
