“…It has been shown that subjecting metal catalysts to plasma discharges can result in a reduction of some metal oxide precursors to generate small active metal crystallites without the use of additional heating. Liu et al [14,15] used a H 2 /N 2 atmospheric pressure glow discharge plasma jet for the reduction of NiO/␥-Al 2 O 3 and NiO/SiO 2 catalysts. A short (10 min) treatment apparently resulted in improved dispersion and smaller nickel particle size compared with thermal reduction.…”

a b s t r a c tThe low temperature reduction of a NiO catalyst by CH 4 was performed in a coaxial double dielectric barrier discharge (DBD) reactor for the first time. The reduction involves active surface carbon which is produced via plasma decomposition of CH 4 . On the reduced Ni catalyst, activation of CH 4 and its fragments to form H 2 and carbon nanofibres occurred at 330 • C. CH 4 conversions of 37% were achieved in the plasmacatalytic reaction at atmospheric pressure, with 99% selectivity towards H 2 and solid carbon. These results demonstrate a synergistic effect where both the plasma and catalyst are vital for the production of H 2 and carbon nanofibres. In the absence of the catalyst stable plasma could not be ignited with a pure CH 4 flow and thermal studies showed that in the absence of the plasma CH 4 conversion was minimal.

Progresses in the Preparation of Coke Resistant Ni‐based Catalyst for Steam and CO₂ Reforming of Methane

Steam reforming of methane is an extremely important process for the hydrogen and syngas production. Nickel‐based catalysts have been extensively employed in the industrial process of steam reforming because of their high activity, low cost, and the plentiful supply of Nickel. Nickel‐based catalysts have also shown high activity for CO2 reforming of methane, which has been considered as a good option, with consumption of a significant amount of carbon dioxide. However, a major challenge is that Ni catalysts have a high thermodynamic potential for coke formation during reforming reactions. For steam reforming, coke formation induces deactivation of the catalyst, especially if the carbon forms as carbon filaments. The filamentous carbon material has a high mechanical strength and can cause mechanical deformation of the catalyst. For CO2 reforming, coke formation over Ni catalyst is even more serious and leads to rapid deactivation of the catalyst. It is highly desired to design and synthesize a coke resistant Ni catalyst not only for reforming of methane, but also for reforming of other hydrocarbons (including biomass derived hydrocarbons). Herein we summarize the very recent progresses in the design, synthesis, and characterization of coke resistant Ni catalysts for steam and CO2 reforming of methane. The progresses in the use of promoters, in the effect of supporting materials and in the preparation methods have been discussed. The thermal stability, regeneration, and future development of coke resistant Ni catalysts for these processes are also briefly addressed.
