Table 2 shows the initial results for the catalytic dry reforming of methane using bulk carbides of niobium, tantalum, molybdenum and tungsten, prepared by CH4 TPR. The conversions and yields obtained over P-M02C and a-WC are very similar to those predicted by thermodynamic considerations, and thus these materials are efficient catalysts for methane dry reforming. At atmospheric pressure, deactivation was observed over both catalysts after about 8 hours on stream. Examination of the post-catalytic samples by powder XRD (Figure 2) revealed that as the reaction proceeded the active P-M02C was oxidised and converted to...

Many other catalytic fluidized-bed processes have been tested at various scales. These include catalytic low-temperature oxidation, catalytic gasification and pyrolysis of biomass and waste plastic, production of carbon nanotubes, dry reforming of methane, hydrogenation and dehydrogenation of hydrocarbons, methanol-to-gasoline (MTC) process, synthesis of dimethyl ether (DME), and selective catalytic reduction of nitrogen... 

A large number of studies have been performed for the development of active and coke-resistant catalysts for the dry reforming of methane. The common catalysts are composed of a metal from group VIII to X supported over an oxide. Noble metals are well known for their high catalytic activities in reforming reactions, but nickel-based catalysts are widely used due to its lower cost... 

Provendier et al. [9] showed that the presence of iron in the perovskite structure LaNi cFei je03 does not improve the catalytic activity in dry reforming of methane but strongly promotes the stability, no carbon deposition being observed after a 250 h of reaction at 800 °C. The formation of a nickel-iron alloy... 

The substitution of nickel by iron was also studied by De Lima et al but the reaction was performed at lower temperature 650 °C [22]. The authors showed that the perovskite LaNio.8Feo 03. among the substituted catalysts, was the most active in the dry reforming of methane. The perovskite phase LaFeOs was observed after 10 h of reaction at 650°C for 0.2 < <0.7 in LaNi Fei c03- Similar results were reported by Kapokova et al. [23] who attributed the high catalytic activity of the substituted materials to the presence of the Ni-Fe alloy released from the perovskite lattice and stabilized on its surface.

Some examples of lanthana as catalysts included the dehydration/dehydrogenation of ethanol [21], the NOx decomposition [4], the NO reduction by methane [22], the oxidative coupling of methane [23, 24] and the combustion of diesel soot [25], As perovskites, the lanthanum compounds showed catalytic activity in fuel combustion [26], carbon monoxide hydrogenation [27], dry reforming of methane [28-30], and partial reforming of methane [31],... 

Catalytic carbon dioxide reforming of methane (dry reforming methane, DRM) is an excellent alternative route to obtain syngas and has received significant attention in recent years due to its scientific and industrial importance, since it converts two greenhouse gases (methane and carbon dioxide) into valuable synthesis The DRM process is industrially...
