Outline
Anisole, a second-generation biomass fuel, has a similar molecular structure to toluene in diesel. Blending of biomass fuels with diesel is seen as a viable solution to the energy crisis. Using a liquid fuel combustion system and selecting n-heptane as the base fuel, the flame morphology, incipient soot size distribution, nanostructure, microcrystalline parameters, orderliness, functional groups and oxidation activity of the soot in the flame of n-heptane, n-heptane blended with volume fraction of 10% toluene, 10% anisole, and 5% toluene/5% anisole were analyzed at an evaporation temperature of 160 ℃. Results show that, for the size and nanostructure of soot particles, the average size of soot in the flame becomes larger under the anisole/toluene blending. For the nanostructure of soot, the blend of anisole and toluene changes the morphology of soot particles and accelerates the soot formation. From microcrystalline parameters, the overall soot structure is more organized after anisole/toluene blending, and the effect of anisole in n-heptane flame on the nanostructure of soot is less than that of toluene. For soot ordering, the intensity ratio of the D1 peak to the G1 peak(ID1/IG1) increases by 17.3% from T10 to A05 and by 11.5% from A05 to A10, respectively, and the degree of graphitization of soot decreases with the increase of anisole blending. The graphitization of soot in the n-heptane flame is minimized when only anisole is blended.
