多孔陶瓷辐射活化柴油的研究

Radiation Activation on Diesel Oil by Porous Ceramics Materials

利用含ThO2多孔陶瓷所产生的辐射来改善柴油的品质,并对被辐照的柴油进行自由基测试。测试结果表明,在紫外光的照射下,由于光催化的作用普通柴油中有自由基信号;而经含ThO2多孔陶瓷处理过的柴油在可见光的条件下,由于ThO2辐射活化作用,自由基信号比普通柴油光催化效果好,实现了微量辐射条件下的光催化(简称辐射活化),提高了光催化效率。说明这种方法能够活化柴油,并能提高柴油的活性,可望用于节油和减少有害气体的排放。

Radiation energy produced by the porous ceramics materials including ThO2 was applied to improve the property of diesel oil. Free radicals in diesel oil were tested. Under illumination of ultraviolet radiation , there is signal of free radicals of ordinary diesel oil because of photo-catalysis. But under visible light radiation, there is more signal of free radicals of diesel oil activated by porous ceramics materials including ThO2 because of radiation activation of ThO2, which proves that diesel oil can be activated by porous ceramics materials including ThO2 under visible light radiation, and improves the efficiency of photo-catalysis. So under visible light radiation, porous ceramics materials including ThO2 can activate diesel oil, improve the activity of diesel oil, which may be applied to oil saved and exhaust emission let reduced.
