Outline of Final Research Achievements

Using a combination of plasma reduction concentration technologies, a new treatment system for CO2 reduction and conversion to fuel is developed and the performance of it is investigated. First, the dimensions of the adsorption chamber which can adsorb 100 % CO2 with a specified flow rate and a concentration are determined experimentally. Next, the specifications of the nonthermal plasma reactor which can reduce 100% CO2 to CO using a plasma circulation flow are determined. As a result, experimental apparatus is completed. In the experimental result with the apparatus, highest removal energy efficiency of 11% is achieved. This value is over three times higher than that obtained by the researchers at University of Michigan ( = 3%)
