Co Precipitation

Mn-Ni-Ox catalyst was prepared by the co-precipitation method. The most active catalysts were obtained with a molar Ni/ (Mn+Ni) ratio of 0.1. The results showed that over this catalyst, NO oxidation conversion reached 59% at 125°C and 50% at 150°C with a high space velocity of 35000h-1. Their surface properties were evaluated by means of scanning electron microscopy (SEM). The process of non-thermal plasma-assisted catalytic oxidation of NO under low-temperature was studied. And the NO conversion could reach 80% with the non-thermal plasma-assisting at 150°C when the input voltage was 30V. The increasing activities at low temperature（50~175°C）were more apparently higher than high temperature by plasma. And the low-temperature catalytic activity of the catalyst was increased with the increase of the input voltage.

AbstractIn order to remove NO from diesel exhaust gas, non-thermal plasma methods have been extensively studied. However, it is known that one of the problems of the de-NOx process by non-thermal plasma is the relatively high energy consumption of the de NOx process. In this paper, we tried to solve this problem by using a water emulsion fuel. Since the use of water emulsion fuel reduces the combustion temperature in the engine, the NO concentration at outlet of the engine should decrease considerably. We prepared a water emulsion fuel with different water content, and carried out NO removal experiments for diesel exhaust gas by both direct discharge and by an ozone injection methods. The experiments showed that a large reduction of discharge power for de-NOx process could be achieved.
