通过微乳化工艺分别把不同含量的精制生物质裂解油与柴油进行混合(micro-emulsified biomass fuel, MEBF)，研究了该类燃油碳烟颗粒的形貌与结构，并对其组分进行了表征。结果表明：该类燃油碳烟的一次颗粒形貌均为球形，而且一次颗粒之间互相连接构成链状团聚物。同时，精制生物质裂解油含量为20%（质量）（BS20）的混合油碳烟颗粒的平均粒径最小，约为32 nm，其他含量混合油碳烟颗粒的平均粒径均在38 nm左右。BS30石墨化程度高于其余碳烟，且BS20颗粒表面C O和C—O—C基团含量较高，可能归因于混合油燃烧过程中复杂含氧组分的氧化程度不同。

Emulsified biomass fuels were prepared via micro-emulsified technology. The morphology, structure and composition of soot particles formed from combusting three kinds of micro-emulsified biomass fuel (MEBF) BS10, BS20 and BS30 in which the content of refined biomass oil were 10%(mass), 20%(mass) and 30%(mass) respectively were characterized using a series of surface analysis tools, and compared with diesel soot particles (DS). The results showed that the morphology of primary soot particles for all three kinds MEBF is spherical and their aggregates are all chain-likes. The average primary particle diameter is smaller for BS20 (32 nm) than for DS (38 nm), BS10 (39 nm) and BS30 (37 nm), while the graphitization degree of soot particles is higher for BS30 than for DS, BS10 and BS20. Besides, the contents of C O and C—O—C functional groups on the surfaces of BS20 particles are higher than those of others. These phenomena possibly were ascribed to the variances of oxidization degree of fuels which involved different oxygen-rich components.
