Steam reforming of aromatic hydrocarbon at low temperature in electric field

Electric Field and Mobile Oxygen Promote Low-Temperature Oxidative Coupling of Methane over La1–xCaxAlO3−δ Perovskite Catalysts

“…Reportedly, the amount of lattice oxygen defect increases by substituting cations with different oxidation numbers in perovskite structures, which promotes redox reaction using lattice oxygen through the Mars van Krevelen mechanism. 21−24 In the present catalytic system, the lattice oxygen contributes to methane activation and C 2 product formation. Therefore, it is considered that Ca doping to LaAlO 3 contributed to increase the amount of lattice oxygen defects, and thereby the conversions and C 2 H 6 + C 2 H 4 yield increased as Ca doping amount increased.…”

Low Temperature Hydrogen Production by Ethanol Steam Reforming over Supported Metal Catalysts in an Electric Field

“…Because acetate species were formed even in the absence of steam, the lattice oxygen (Olat) of CeO2 support might contribute to oxidation of ethoxide to acetate. We reported earlier that lattice oxygen participates in the oxidation of hydrocarbons, even at low temperatures, when the electric field was applied 32) . Therefore, promotion of the redox reaction by the electric field using the lattice oxygen is expected to contribute to oxidation of ethoxide to acetate species.…”

Enhanced activity of catalysts on substrates with surface protonic current in an electrical field – a review

“…However, the power consumption by the field and current is low (typically 2 W, maximum 8 W) and the effect of the temperature rise of the catalyst bed on the reaction is small, confirmed by the thermocouple. Therefore, the induced Joule heat is estimated to be negligible in this process 48,49 . Attempts to measure the catalyst temperature during the application of the electrical current in ammonia synthesis experiments have also been made in a setup at University of Oslo employing a ProboStat™ sample holder system (NORECS AS, Norway) with a wider quartz tube bed reactor equipped with Au mesh electrodes and taking up to 1 g catalyst.…”
