We have been investigating NOx removal superimposing barrier discharges for exhaust gases from diesel engine. In this research it is considered that tourmaline and Shirasu are effective on the NOx removal by electric discharge. As the result of experiment, the beads mixed tourmaline and Shirasu showed higher adsorption effect. NO removal concentration of 38ppm was obtained by self-enhancement electric field in the mixture beads. NO molecule adsorbed with mixture beads was removed by electric discharge. NO removal rate was about 100% when gas flow rate of 400mL/min and discharge power of 4.3W were used. NOx removal rate was about 50% when gas flow rate of 600mL/min and discharge power of 7.0W were used. NO removal efficiency of about 28g/kWh was obtained when gas flow rate was 600mL/min and NO removal rate was 50% were used. Packed bed reactor was filled up with the beads mixed tourmaline and Shirasu. Using mixture beads and electric discharge at the same time was effective for NOx removal.

我们一直在研究柴油机废气中氮氧化物的去除叠加阻挡放电。在本研究中，它被认为是有效的电气石和白苏放电脱硝。实验结果表明，电气石和白素混合的微珠对水有较好的吸附效果。在自增强电场作用下，混合珠对NO的去除浓度可达38 ppm。混合小球吸附的NO分子被放电去除。当气体流量为400 mL/min，放电功率为4.3W时，NO去除率接近100%。当气体流量为600 mL/min，放电功率为7.0W时，NOx去除率约为50%。当气体流量为600 mL/min，NO去除率为50%时，NO去除率可达28 g/kWh。填充床反应器填充有混合的珠状电气石和白素。采用混合颗粒与放电同时进行脱硝是一种有效的脱硝方法。
