Exhaust Purification

Herein, a novel process of diesel exhaust purification by non-thermal plasma combined with wood fiber has been investigated to understand the effect of purification efficiency on the emission. The dielectric barrier discharge (DBD) and wood fiber (WF) improved removal efficiency of nitrogen oxide (NOx) owing to the positive activity of oxygen-containing functional groups (such as O–H groups or C–O groups) on the wood surface, which promoted the removal of NOx by 10%–13%. The mechanism to remove NOx in the presence of wood fibers was also deduced through FTIR spectra. When carbon black was loaded on the wood fiber, there was simultaneous removal of carbon soot and NOX. Although complete purification was not achieved, a high purification efficiency was obtained under the conditions of room temperature and no catalysts. These advantages highlight the importance of use of wood and non-thermal plasma (NTP), and this research work opens new avenues in the field of emissions treatment.

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.

The variation of carbonyl compounds in diesel exhaust at four loads before and after the treatment of Direct Non-thermal Plasma (DNTP) is studied with 2,4-dinitrophenylhydrazine (DNPH) derivatization method and high performance liquid chromatography (HPLC) analysis technique. The results show that the mass concentration of carbonyl compounds decreases firstly and then increases with the growing of diesel load before the treatment of DNTP. After the treatment of DNTP, the mass concentration of carbonyl compounds reduces remarkably. Maximum removal efficiency for total carbonyl compounds can reach 93.8% at 75% load. For acrolein, acetone, butyraldehyde and 2-butanone, removal efficiency can reach 100% at 25% load, 50% load and 100% load. At the same time, total ozone formation potential decrease dramatically.
