纳米铝对硝基甲烷快速反应的催化研究
The study of fast reaction of nitromethane calytized by nano-aluminum
摘要
Abstract
Fast reactions between nitromethane and aluminum nanoparticles have been studied in incident shock waves. The emergence time and emission spectra intensity of partial products, such as NO_2、CO、CO_2、CH_2O、H_2O and AlO were observed by transient spectral methods. In comparison to species produced by pure nitromethane, emergence time for species produced by nitromethane (1ml) after addition of nano-aluminum (1g) decrease by 46~60% and the emission intensity increase by 30~100%, the shockwave diffusion velocity and reaction temperature increase by 1.4 times and 2.2 times, respectively. The results demonstrate that nano-aluminum have positive effect on accelerating the decomposition rate of nitromethane and that the explosion efficiency of nitromethane was greatly improved. Based on the experimental results, combined with thermodynamic and kinetic analysis, the exploratory studies on fast reaction of nitromethane calytized by nano-nanoparticles were discussed. The investigation may provide insights into the process occurring in actual systems involving fuel air explosives (FAE).关键词
