An investigation of CO2 splitting using nanosecond pulsed ...

The plasma chemical splitting of carbon dioxide (CO2) to produce carbon monoxide (CO) in a pulsed corona discharge was investigated from both an experimental and a numerical standpoint. High voltage nanosecond pulses were applied to a stream of pure CO2 and its mixture with argon, and the gaseous products were identified using Fourier transform infrared spectroscopy.

Gasentladung, ein meist mit einer Leuchterscheinung verbundener Durchgang eines elektrischen Stromes durch ein Gas oder einen Dampf, wobei die Leuchterscheinung vom Druck und von der Stromdichte abhängig bestehen aus elektrisch neutralen Molekülen oder Atomen, sie besitzen keine oder nicht genügend Ladungsträger zur Leitung des elektrischen Stromes, so daß einer ...


Carbon Dioxide Decomposition by Plasma Methods and ...

Then carbon dioxide gas was injected to react with activated sample. The rates of carbon dioxide decomposition using activated Rh, Pt and Ce materials were larger than that of the activated NF. The effect of metal impregnation on the activation and carbon dioxide decomposition increased in the order of Ce < Pt < Rh. In another study the thermal decomposition of carbon dioxide in a dense mixed ...

Effects of catalysts in carbon dioxide reforming of ...

The effects of two kinds of representative catalysts, Ni/Al2O3 and HZSM5 zeolite, were investigated in the CO2 reforming of CH4 via corona plasma reactions at atmospheric pressure. The catalysts showed little effect on the conversions of CH4 and CO2, and we propose that rapid freeradical processes play a main role during the plasma reactions. However, although a highvoltage electric field ...

Plasmen als Chemielabor Newsportal RuhrUniversität Bochum

18/06/2021· Plasmen als Chemielabor. Je kleiner ein Plasma, desto größer ist oft der Messaufbau, um es zu untersuchen. Der Aufwand lohnt sich, denn in KubikMillimeter kleinen Plasmen finden sich Reaktionsbedingungen wie nirgendwo sonst. Plasmen mit Atmosphärendruck sind oft nur wenige KubikMillimeter groß – aber trotzdem haben sie es in sich.
