针对脱硫剂制备过程中加入不同添加剂及不同添加量对石灰消化速度、消化后消石灰的比表面积和孔隙率，以及消石灰脱硫性能的影响进行了试验研究。试验结果表明某些添加剂在一定添加量时提高了消石灰的比表面积和孔隙率。在脱硫试验中，添加这几种添加剂制备成的吸收剂具有较高的脱硫性能。可以认为吸收剂脱硫性能的提高与其结构特性的变化有关系。将这几种添加剂在不同的添加量时两两组合制备成不同配比的复合型添加剂，并对复合添加剂影响石灰结构特性和脱硫性能的作用进行了初步试验研究，得到了具有较高脱硫性能的复合型添加剂的组合成分及其配比。

Removal of NOx (namely DeNOx) from simulated flue gas with direct current (d.c.) corona radical shower system was investigated. Steady streamer coronas occur when the flow rates of the fed gases are adjusted properly. The experimental results show that both the composition and the flow rate of the gas fed into the nozzles influence the V -I characteristic of corona discharge. The vapor in the flue gas restrains the discharge, reduces the discharge current, but enhances the DeNOx efficiency. Furthermore, removal of NOx from flue gas by radical injection associated with alkali solution (26% by weight of NaOH in water) scrubbing was carried out. Oxygen together with water vapor is fed into the nozzle electrode and the oxygen and water molecules are decomposed in the corona zone. It is found that NO and NO2 can be converted into HNO2 and HNO3, respectively, by radicals formed during the discharge process and the conversion efficiency of NOx in the plasma reactor is more than 60%. The overall DeNOx efficiency of the system reaches 81.7% after the flue gas was scrubbed by the NaOH solution.

This paper researches on the reduction of NOx (DeNOx) from wet flue gas by a DC corona radical shower system. The experimental results show that the water vapor in the flue gas not only reduces the corona but also reduces the discharge current. The DeNOx efficiency and the quantity of NOx removal per unit energy can be enhanced by raising the concentration of water vapor in the flue gas properly and the maximum quantity of NOx removal per unit energy is more than 25.5 g as the humidity of the flue gas ranges from 10 to 12%. The longer the flue gas resides in the reactor, the higher the DeNOx efficiency is and the lesser NOx will be reduced by per unit power.

Removal of NOx (DeNOx, NOx is the total of NO and NO2) from flue gas by radical injection has been investigated. The discharge characteristics were examined and the steady streamer corona was acquired by adjusting the nozzle gases properly. It was found that an increase in the voltage resulted in a decrease in the NO concentration and the concentration of the NO2 increased at low voltages but decreased as the voltage rose to a certain level. The DeNOx efficiency increased as the applied voltage rose and reached a maximum of 70% when the voltage approached the break. down voltage. The hypotheticaI mechanism Of NOx removal suggested that the radicals formed in the discharge process converted the NO and NO2 into acidic species. The Monte CarlO method was used to calculate the rate COemcients and the productivity of the radicals, and then the concentrations of both NO and NO2 and the DeNOx emciencies were calcu. lated with chemical kinetics. The calculated DeNo, efficien. cies were comparable with the experimental DeNOx efficien-cies at low voltages, but were lower at high voltages.

Non-thermal plasma technologles offer an innovative approach to decomposing valatile organic compeunds (VOCs). The decompoesition of toluene from simulated flue gas was investigated using a pipe electrode with lor the for the generation of free radicals Corona characteristics and decomposition of toluene were investigated experimentally. In addltion, the decompesition mechanism of toluene was explored in view of reaction rate The experimental results showed that the humidity of additional gas has an important effect on corona characteristics and modes and stable stresmer corona can be generated through optimizing flow rate and humidity of additional gas. Applied vo#age, concentration of toluee, humidity of toluene and resident time are some important fictors affecting decomposition efflciency. Under optimizing cond~ions, the decomposition efficiency of toluenecan reach 80%. These results can give a conclusion that the corona radical shower technology is feasible and effective on the removal of toluene in the flue gas.
