“…have been alloyed with Ni to improve the thermal stability and coke resistance of Ni nanoparticles. [28][29][30][31][32] Considering the high cost and limited availability of the precious metals, the development of Nibased bimetallic catalysts owing desirable coke resistance and long-term stability without precious metals is then highly desired. Moderate Cu addition to Ni has been reported as an effective catalyst used in modest-temperature catalysis such as water-gas shift and ethanol steam reforming, and therefore would be good catalyst for DRM.…”

“…In contrast, the Ni 0.5 Mg 2.4 Cu 0.1 Al catalyst exhibits rather stable performance for 20 h on stream without apparent variations in the selectivities to products. The improved stability may be caused by the formation of small Ni particles well dispersed on the catalyst surface[37].…”

Cu-promoted NiMgAl catalysts derived from hydrotalcites were synthesized by the urea hydrolysis method for ethanol steam reforming. The effect of Cu content on catalytic properties of the NiMgAl catalysts was studied. These catalysts were characterized by X-ray diffraction, thermogravimetric and differential analyses, X-ray photoelectron spectroscopy, Fourier transform infrared spectroscopy and temperature-programmed reduction. The addition of small amounts of Cu to NiMgAl catalysts leads to the increase of surface Ni species and the enhancement of Ni 2? reducibility. The Ni 0.5 Cu 0.1 Mg 2.4 Al catalyst with Cu/Ni ratio of 0.2 exhibits the higher activity and stability, showing no apparent deactivation during 20 h on stream at 700°C, whereas Ni 0.5 Mg 2.5 Al catalyst suffers severe deactivation only after 10 h on stream. This improved performance is closely related to smaller nickel particles well dispersed on the catalyst surface. The Ni 0.5 Cu 0.1 Mg 2.4 Al catalyst exhibits strong resistance to coke formation and the sintering of nickel particles.

“…Total reforming time was 3 h, with standing time of 1 h at the following temperatures: 873, 973 and 1023 K. The reaction was carried out in a fixed-bed quartz reactor at atmospheric pressure. When temperature in the reactor reached 873 K, CH 4 and CO 2 (CH 4 :CO 2 = 1:1) were allowed to pass through the catalyst bed at a total flow rate of…”

“…CO and H 2 mixture, is a valuable raw material that can be used in the Fischer-Tropsch synthesis to produce liquid fuels. Dry reforming of methane (DRM) presents a promising technology for syngas production, because two greenhouse gases (CH 4 and CO 2 ) are simultaneously utilized. The DRM is commonly carried out at temperature range from 973 K to 1173 K, in the presence of catalysts based on noble and non-noble metals.…”

In the present study, Ni-Pd/Al 2 O 3 catalyst supported on α-Al 2 O 3 based foam was prepared and evaluated in the dry methane reforming process. Corresponding metal chlorides were deposited to the foam surface by impregnation of the foam with ultrasonically aerosolized salt solutions at 473 K and drying at that temperature. Calcination step was excluded and the catalyst was reduced at very low temperature -533 K. The reforming experiment lasted for 3 h, with standing time of 1 h at the following temperatures: 873, 973 and 1023 K. Conclusions on selectivity, catalytic activity and stability were reached on the basis of CO and H 2 yields.
