“…The partial oxidation of methane is a catalytic process in which methane reacts directly with oxygen in the presence of a catalyst, and the product of this reaction is the syngas which is shown with a H 2 /CO good ratio (Fathi et al, 2000). The scheme of the partial oxidation of methane is shown below.…”

“…The use of noble metals, particularly Pt and Rh as active species for catalytic reforming of the methane processes attract much interest because they lead to excellent results. However, they are very expensive (Hickman & Shimidt, 1992;Monnet et al, 2000;Fathi et al, 2000). Through scientific research was discovered that Ni when tested under reaction conditions of reforming of methane process, the catalytic performance and the quality of the product output are equivalent to the final results obtained by noble metals such as Pt and Rh.…”

“…Both CH 4 activation and mechanistic studies on CRM over different catalysts were intensively investigated by using the pulse technique combined with other techniques [17,18,[20][21][22][23][24]. In this paper, pulse reactions of CH 4 , CO 2 and CH 4 were systematically performed to further investigate the performance of the catalyst.…”

A nano Pt/MgO catalyst was prepared by the wet impregnation method. Decomposition of methane and CO 2 reforming of methane (CRM) were investigated by using temperature programmed reaction (TPRa), D 2 -CH 4 isotopic exchange reaction, pulse reaction and temperature programmed surface reaction (TPSR). The results show that the nano Pt/MgO catalyst with Pt loading 1.05 wt% has high activity for CH 4 decomposition and the CRM reaction. The results of D 2 -CH 4 exchange experiments showed that the Pt/MgO catalyst was very effective for the activation of methane, which is one reason why the catalyst has high activity for CRM. The results of the pulse reaction give a similar idea and the treatment of the catalyst influences the activity for CH 4 activation.

“…Nevertheless, the authors speculated that the CO selectivity might be controlled by the relative rate of the CO oxidation and desorption reactions, and that the rate of CO oxidation is sensitive to the degree of oxide reduction. Fathi et al investigated CeO 2 supported on c-Al 2 O 3 promoted with Pt or Rh for partial oxidation of methane [15,16]. A relationship between selectivity to syngas and degree of reduction of the oxide was observed.…”

The reaction between CH 4 and framework oxygen of Pt promoted Ce x Zr 1-x O 2 (x = 0.25, 0.5, 0.75, 1) solid solutions was studied at 873 K for syngas (CO ? H 2 ) production. The homogeneity and cubic/tetragonal structure of the solid solutions were confirmed by powder X-ray diffraction. The thermodynamic properties of the solid solutions, connected with Ce 4? /Ce 3? redox reactions, were measured by titrating the oxygen content of the oxides after equilibration in flowing mixtures of H 2 and CO 2 with 10 -31 \ pO 2 \ 10 -22 atm. The transient reactions between the oxides and discrete pulses of CH 4 , as well as of isotopically labeled 13 CH 4 ? 12 CO mixtures (limited to the material with x = 0.25) were investigated and reactivity, conversion and selectivity were measured. A strong correlation between the thermodynamic properties of the oxides and the syngas selectivity was found. The 13 C scrambling in CO and CO 2 during co-feed experiments confirmed equilibration of these molecules with the oxides surfaces.
