Syngas production by methane oxy-steam reforming on Me/CeO2 (Me = Rh, Pt, Ni) catalyst lined on cordierite monoliths

Hydrogen-rich gas production by steam reforming of n-dodecane

“…The slight loss of activity, recorded by increasing space velocity, could be due to different causes: n-dodecane steam reforming is a strongly endothermic reaction often limited by heat and mass transfer, especially in packed bed reactors [49,50]. These phenomena enhanced at higher space velocity, could contribute to the decrease of the catalytic performance.…”

Performance evaluation and comparison of fuel processors integrated with PEM fuel cell based on steam or autothermal reforming and on CO preferential oxidation or selective methanation

“…For the unburned fuel, according to the experimental evidence in the literature [14,15], a complete conversion to syngas (H 2 , CO, CO 2 , H 2 O, N 2 ) is assumed. The steam is fed to both SR and ATR with a S/C molar ratio of 3 to make negligible the carbon formation and to ensure water self-sustainability of the whole system [38,39]. Moreover, methane formation (as undesired product of parasitic methanation reaction) is assumed insignificant, being the SR reaction predominant at high S/C ratio values over 400-500°C range [101].…”

Active and Stable Methane Oxidation Nano-Catalyst with Highly-Ionized Palladium Species Prepared by Solution Combustion Synthesis

“…A similar peak was assigned by Venezia et al and Bi et al to Pd 4+ , as in PdO 2 , due to the oxygen incorporation into the PdO crystal lattice during calcinations [52]. The highly ionized Pd ions of the samples prepared by the SCS can also be assigned to Pd ions which were inserted into the ceria lattice forming pallida/ceria solid solution [23,38,53]. The appearance of the three Pd XPS doublets, comparing to only two Pd XPS doublets for the impregnation catalyst, strongly indicated the formation of Pd/ceria solid solution as has already been reported in recent literature [23,36,38].…”

“…The reaction is exothermic in nature and proceeds auto-thermally without further external heating after initiation of combustion. A detailed description of the synthesis procedure is provided elsewhere [31][32][33]35,44,47,53,[67][68][69][70][71]. The synthesized nano-powder was then sintered in air by heating at a rate of 1 • C min −1 until it reached 800 • C where it was maintained for 3 h before cooling to room temperature at a rate of 1 • C min −1 .…”
