项目摘要
The objective of the research is to remove high concentration (1,000〜2,000ppm) NOx and SOx at high flue gas gas temperature (>250℃), and also to remove particulate matters (PM) from diesel engine and boiler emission. The adsorption and plasma hybrid process were employed to control the diesel emission and the plasma chemical hybrid process was employed to control the boiler emission. In the dry process for diesel emission control, the adsorbent using molecular shieve (MS-13X) was used to adsorb NOx effectively, and adsorbed NOx were desorbed and regenerated using N2 by means of heat in the diesel emission system. The desorbed high concentrated NOx were totally reduced by the nonthermal plasma to form N_2 and O_2. Since the moisture content in the diesel engine was affected by NOx adsorption process, the use of silicate was investigated. As the results, the use of silicate was to place upstream of the adsorbent.(or high temperature side). Other hydrophobic adsorbent such as Mn based ads … More orbent was also found to be extremely suited for NOx adsorption. We also found that NOx desorption by heat took place effectively even at 120℃ and NOx concentration was increased with repetitive thermal desorption and reached a constant desorption efficiency beyond 7 repetitive desorption process. As far as PM is concerned, PM was trapped with the conventional diesel particulate filter (DPF) and incinerated with either NO_2 at the gas temperature of 250℃ and O_3.even at the room temperature.On the other hand, the plasma chemical process used for boiler emission control, ozpnizer was used to oxidize NO to form NO_2 in the gas stream and formed NO_2 was reduced by the chemical scrubber using Na_2SO_3 solution to achieve N_2 and water soluble and nontoxic Na_2SO_4. The required amount of O_3 was approximately one stoichiometric of NO concentration in the gas stream. The NOx reduction was affected by CO_2 and O_2 concentrations in the gas stream and the optimization study was performed, resulting that more that 85% of NOx reduction was achieved throughout the experiments.

研究的目的是在高烟气温度(>;250℃)下脱除高浓度(1000~2000ppm)的NOx和SOx,并脱除柴油机和锅炉排放的颗粒物(PM)。采用吸附和等离子体混合工艺控制柴油机排放,采用等离子体化学混合工艺控制锅炉排放。在干法柴油机排放控制中,采用分子筛(MS-13X)吸附剂对NOx进行有效吸附,并在柴油机排放系统中利用氮气对吸附后的NOx进行解吸和再生。解吸后的高浓度NOx被低温等离子体完全还原为N_2和O_2。由于柴油机中的水分受NOx吸附过程的影响,因此对硅酸盐的利用进行了研究。结果表明,硅酸盐的使用是放置在吸附剂的上游(或高温侧)。其他疏水吸附剂,如锰基ADS…更多的脱氧剂也被发现非常适合于NOx的吸附。我们还发现,即使在120℃时,NOx也可以有效地进行热解吸,重复热解吸可以增加NOx的浓度,并在重复解吸7次后达到恒定的解吸效率。对于PM来说,PM被传统的柴油微粒过滤器捕获,并在250℃的气体温度下和O_3一起焚烧,即使在室温下也是如此。另一方面,用于锅炉排放控制的等离子体化学过程,利用臭氧发生器氧化气流中的NO生成NO2,并通过Na2SO3溶液通过化学洗涤器还原生成NO2,得到N_2和水溶性无毒的Na_2SO_4。研究了气流中CO_2和O_2浓度对NOx脱除效果的影响,并进行了优化研究,整个实验过程中脱氮率达到了85%以上。较少
