Investigation of Atmospheric Pressure Plasma Source for CO2 Dissociation
نویسندگان
چکیده
This work experimentally investigates the dissociation of CO2 in an atmospheric pressure surface-wave discharge. A 2-kW microwave power supply is used to sustain the plasma contained in 1-cm-diameter quartz tube. Optical emission spectroscopy is recorded at varying axial positions along the quartz discharge tube to give evidence of the different species present. Diagnostics taken with a residual gas analyzer are used to monitor the evolution of atomic and molecular species in the system, revealing CO and oxygen as the main products of the plasma-chemical reactions. For plasma-assisted CO2 dissociation to be a practical and cost-effective solution for the climate change challenges, the process must meet certain standards of efficiency. Therefore the energy efficiency and conversion efficiency of the plasma system is examined for CO2 dissociation.

Dissociation of Co2 in a Radio-frequency Plasma Source
Current dependence on fossil fuels to satisfy increasing energy needs has created an overabundance of CO2 emissions. This project aims to use a radio frequency (rf) plasma source to dissociate CO2 completely into solid carbon and gaseous oxygen to reduce CO2 concentrations in the atmosphere. An rf plasma excited by a double helix antenna with an axial magnetic field is used to create the CO2 di...
