About the Project
CO2 should be converted to useful products rather than simply be captured. Non-thermal plasma reactors operating at ambient temperature can be used to convert CO2 to various other species in reactions that are not observed in conventional chemistry until 1000s of oC. This is possible because the reactions are initiated by energetic electrons produced by a strong electric field. This changes what is possible in CO2 chemistry, opening up the possibility of a variety of “useful” species.
This project will use a form of non-thermal plasma reactor, known as a dielectric barrier discharge (“DBD”) reactor, and appropriate catalysts to convert CO2 into CO and O2 and other products, including potential fuels, at low temperatures (<120 oC) and ambient pressure. Conversion to CO will effectively “activate” CO2, as CO is reactive, whereas CO2 is relatively unreactive. CO could then be reacted with H2 to create a range of longer hydrocarbons, for example.
The overall aim of the research project is to improve the energy efficiency of this reaction. Key reaction parameters such as plasma power, residence time and reactor configuration will be varied systematically. To improve efficiency various catalysts will be evaluated. Catalysts typically lead to greater efficiency in this type of process, by reducing the power requirement, and improving selectivity. The catalysts to be used here include alumina, Ni/Al2O3, Fe/Al2O3, Co/Al2O3, SiO2, and TiO2.
