Methane Steam Reforming on the Pt/CeO2 Catalyst: Effect of Daily Start-Up and Shut-Down on Long-Term Stability of the Catalyst

“…In cyclic operation, catalysts usually show degradation and need regeneration after some time-on-stream (TOS). Many researchers have studied the cyclic daily start-up and shut-down of catalysts with and without regeneration. ,− Li et al studied the self-regenerative activity of Ni/Mg­(Al)O at 900 °C under the cyclic condition for 6 h: with steam purging of the catalyst in between the shut-down and start-up, they found a stable activity. Most of these studies are conducted away from equilibrium conditions, where methane conversion is low.…”

Future Power Train Solutions for Long-Haul Trucks

“…However, research on fuel cell systems with on-board fuel processing for vehicle propulsion was halted due their high complexity [13]. The technology can still be used for power supply to mobile systems during idling [14][15][16][17][18][19][20]. Instead of fossil fuels, biofuels could be employed by Internal Combustion Engines (ICEs).…”

Recent Advances in Structured Catalytic Materials Development for Conversion of Liquid Hydrocarbons into Synthesis Gas for Fuel Cell Power Generators

“…This approach promotes the efficiency of fuel consumption in modes when the main engine is either turned off or idling during stops, loading/unloading operations in cargo terminals, airport parking, etc. [ 2 , 3 , 4 , 5 , 6 ].…”

“…The low sulfur content (≤0.001 wt.%) in diesel fuel of modern grades greatly promoted the development of fuel processors [ 3 , 8 , 9 , 10 ]. Indeed, over the past decade, the number of R&D works aimed at finding and studying catalysts for the conversion of kerosene [ 3 , 4 , 11 , 12 , 13 ], diesel [ 14 , 15 , 16 , 17 ], renewable natural raw materials—biodiesel [ 18 , 19 ] and glycerin (a by-product of biomass processing) [ 20 ]—as well as fuel processor designing [ 5 , 6 , 13 ], has increased significantly [ 2 , 4 , 5 , 6 , 11 , 13 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 ].…”

“…Laboratory studies showed that the Rh- and Rh-Pt-based ceramic block catalysts exceed in activity, selectivity and stability other catalytic systems at diesel ATR [ 55 , 56 , 57 ]. Quite naturally, cordierite-supported RhPt/Al 2 O 3 -CeO 2 commercial catalysts (Umicore AG&Co. KG, Hanau, Germany) were used in pilot tests of more than a dozen fuel reformer modifications performed by the research team from Forschungszentrum Jülich (Jülich, Germany) [ 4 , 5 , 6 ]. To reduce temperature heterogeneity at diesel ATR, induced by the high exothermic effect of oxidation reactions, proceeding predominantly in the frontal zone of the catalytic block, and the high endothermic effect of the reactions of steam and carbon dioxide reforming, which take place in its tail section, it seems reasonable to use, instead of cordierite ceramics, a metal support composed of FeCrAl wire mesh, which has a high thermal conductivity [ 89 ].…”
