Adsorbed CO2 Dissociation Using Argon and Helium Nonthermal Plasma Flows
In recent years, global warming has become a world-wide problem. Carbon dioxide (C02) is main substances for global warming and its emission should be reduced. One of the promising technologies is the conversion of CO2 to CO by plasma treatment, so that CO itself or its conversion to methane can be used as fuel for combustion engines. In this study, CO2 dissociation or reduction treatment system using an adsorbent and nonthermal plasma (NTP) flow is investigated. In this study, in order to improve the conversion efficiency, the conversion efficiency for Ar or He plasma is evaluated. In physical adsorption process, approximately 10% CO2 gas with a flow rate of 10 L/min is prepared, and then it is introduced into the flow channel and CO2 is adsorbed by the adsorbent. After the adsorption process the circulation flow channel is set and then the Ar or He plasma flow is generated with a blower. As a result, the CO2 adsorbed by the adsorbent is desorbed with CO2 concentration of 20 and 23 % by Ar or He plasma flow, respectively. More than 10 % of the conversion energy efficiency of desorbed CO2 to CO is obtained with plasma power of 300 W.
