摘要/Abstract

摘要： 点火和燃烧是高密度燃料在新型发动机上应用的关键技术之一。使用十八酸作为保护剂制备了纳米钯金属颗粒，采用红外、核磁、差热分析和透射电镜等手段对其进行了表征。发现颗粒的平均粒径随着合成液中十八酸与钯前驱化合物摩尔比的增加而减小，纳米颗粒可长期稳定分散在燃料中而不沉降。评价了纳米颗粒催化高密度燃料HD-01的点火燃烧性能，发现添加质量分数为0.01‰，十八酸/Pd原料配比为4:1的颗粒可将HD-01的点火燃烧温度降低约230°C。

Abstract: Ignition and combustion are very important for the application of high density fuel in new aerospace engines. Stearic acid monolayer protected palladium nanoparticles were synthesized and characterized by FTIR，NMR，DTA and TEM. It is found that the particle size decreased with the increase of stearic acid/Pd molar ratio in the synthetic mixture. And the particles were well dispersed in fuel very stably. The catalytic performance in high density fuel (HD-01) ignition and combustion was evaluated. The results show that the addition of 0.01‰ Pd MPCs(the stearic acid/Pd ratios are 4:1) in HD-01 could reduce the ignition temperature by about 230°C.

Key words: Applied chemistry；High density fuel；Metal nanoparticles；Catalytic combustion；Fuel soluble catalyst
