Abstract

Soot formation is one major challenge in developing clean and efficient utilizes based on hydrocarbon fuels. In this work, ferric nitrate was selected as an iron additive to be loaded into pulverized coal, and the pyrolysis experiment with an inert atmosphere was conducted in a high-temperature drop tube furnace (DTF). The physical and chemical character of the soot obtained from coal samples with different iron content were analyzed to explore the effect of the soot format process. The results showed that the soot yield was reduced 7% and 23%, respectively, at the same conditions when the content of iron in the coal sample was 0.51% and 0.87%. After iron was added, the diameter of soot primary particles was reduced from 50.8 nm to 37.4 and 37.8 nm, and the Df of soot aggregates increased, indicating that iron inhibited the growth process of soot primary particles and promoted the agglomeration between particles. Thus, the degree of graphitization of soot increased. In addition, the content of C–O functional groups in soot derived from coal with iron addition increased significantly, which implied that the participation of iron enhanced the oxidation reaction of soot.
