Abstract
Carbon monoxide (CO) is an extremely harmful gaseous pollutant causing serious poisoning symptom. CO generation also creates various environmental pollution problems such as a photochemical oxidant, acid rain and the global warming. CO was generated from various sources such as power generation facilities, manufacturing factories, automobile vehicles as well as homes heating facilities by incomplete combustion. The aim of our research was focused on CO oxidation using the atmospheric barrier discharge plasma reactor. The influence of moisture content and oxygen concentration on CO oxidation was investigated. As a result, the CO conversion was improved with increasing moisture content due to oxidation reactive species such primarily OH radicals but was reduced with increasing oxygen concentration. This was attributed to the reduction of O radicals which reacts preferentially with OH radicals but not for CO oxidation for this experimental condition.
