Abstract

It is crucial to reduce soot emission from combustion. Organo-Pd compounds as fuel additives are proven to have catalytic effect on enhance ignition and combustion. However, its effects on soot emission and the mechanism are not well-understood. In this work, palladium acetylacetonate was added in ethylene combustion and its effect on the soot formation and growth was studied. The synchrotron small angle X-ray scattering (SAXS) was used to in situ detect the soot particles to obtain the size, shape and morphology information. The Pd(acac)₂ addition suppresses the growth of the primary soot particles, but does not affect much the morphology of the aggregates. Detailed size distribution and particle morphology at different flame heights are discussed.
