The pollution caused by vehicle exhaust is a serious environmental issue that affects public health. Policymakers have implemented several regulatory measures, such as clean fuel legislation and catalytic converters, to reduce automobile exhaust emissions. However, these strategies may have negative effects like increased fuel consumption and decreased engine performance. Researchers are looking into cutting-edge technologies like non-thermal plasma (NTP) to reduce nitrogen oxide (NOX) emissions from vehicle exhaust. An affordable and energy-efficient method of eliminating NOX is to use NTP, a type of plasma that functions at room temperature and pressure. A multitude of factors, such as the type of plasma reactor and operating conditions, affect how well NTP removes NOX. The electrode layout we are suggesting in this study exhibits a notable increase in injected power when compared to the traditional cylindrical electrode shape. Furthermore, the NOX removal is enhanced by use of cascaded adsorbent reactor containing MS13x/activated alumina. In our study, alumina is used as adsorbent at room temperature and the spike electrode with activated alumina showed the best removal efficiency.
