Catalytic steam reforming of glycerol for H(2) production has been evaluated experimentally in a continuous flow fixed-bed reactor. The experiments were carried out under atmospheric pressure within a temperature range of 400-700 degrees C. A commercial Ni-based catalyst and a dolomite sorbent were used for the steam reforming reactions and in situ CO(2) removal. The product gases were measured...

Hydrogen, presently, finds application as a chemical rather than a fuel in commercial operations. However, being a non-polluting source of energy, hydrogen is predicted to be the ‘‘fuel of the future’’. One of the most potential applications for hydrogen is to power fuel cells. Major automobile manufacturers are currently working towards developing fuel cell vehicles; such vehicles are expected...

Solid oxide fuel cells (SOFCs) have the potential to revolutionise the present fuel economy due to their higher fuel conversion efficiency compared with standard heat engines and the possibility of utilizing the heat produced in a combined heat and power system. One of the reasons they have yet to fulfil this potential is that the conventional anode material of choice, a nickel/yttria-stabilise...

The modular catalysts were fabricated via the combination of the Ni-MgO-Al2O3 mixed oxide nanoplates and the mesoporous SiO2 coating. Due to the dual confinements, the catalysts show high catalytic activity with enhanced coke- and sintering-resistance in the dry reforming of methane reaction.

The highly dispersed Ni nanoparticles in mesoporous silica were achieved via using polyol as new delivery conveyors and removable carbon templates. The catalyst exhibits excellent coking- and sintering-resistance in dry reforming of methane attributed to the controlled size and location of Ni nanoparticles.

Monolithic catalysts derived from in situ supported hydrotalcite-like films on Al wires display high resistance to coke formation and sintering in the dry reforming of methane due to their hierarchical porous structure, well dispersed metallic nickel species, more basic sites and strong metal-support interaction effect.

Dry reforming of methane (DRM) has been investigated under an electronactivated catalytic bed in a thermo-electrical reactor. The main objective of this work was to investigate what the impact of the electrical current on the conversion of methane is. The combination of thermal and electrical energy allowed achieving higher conversions for both reactants at temperatures varying from 850–950°C. ...

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...

The reforming of methane with CO2 was carried out efficiently in a fluidized bed reactor at 973 K under atmospheric pressure, taking advantage the nickel catalyst efficiency achieved particulate fines. fluidization operation characterized by determining minimum velocity 3.11 × 10−3 ms−1 and higher velocities. worked surface speeds up to 1.84 10−2 ms−1, providing conversions from 45% 51% syngas ...

This article reviews research related to the activation of methane by Ni and Ru using model catalysts, highlighting the surface science work carried out using molecular beams methods and elevated pressure reaction studies. Emphasis is placed on connecting the model studies of surface science with the corresponding results obtained on the analogous ‘real world’ catalysts. These combined studies ...
