Catalyst Size Impact on Non-Thermal Plasma Catalyst Assisted deNOx Reactors

摘要：

Non-thermal plasma assisted catalytic reaction is an effective way to remove NOx from automobile exhaust. Dielectric harrier discharge is used to generate non-thermal plasma in a packed bed of solid catalyst particles acting as dielectric in this study.The size of the catalyst particle affects gas-solid phase chemical reactions. At the same time, the geometry of the particles affects the space factor of the packing and the characteristics of the dielectric harrier discharge, such as power. The NOx removal efficiency is also affected. The results of this study show that the diameter of the catalyst particle affects NOx removal efficiency.A minimum peak value of discharge power can be found at a specific particle diameter for a given reactor and power supply. NOx removal efficiency increased with the size of the catalyst to a peak before decreasing on a similar pattern. Therefore an optimum pellet size can be found that that gives maximum removal efficiency. In a catalyst packed bed reactor assisted by dielectric barrier discharge it is important to choose the optimum diameter of catalyst particle.
