Abstract

High-intensity ultrasound was applied to an automotive diesel fuel using a 23 kHz 'horn' system. The saturated components of the fuel undergo similar reactions to pure n-alkanes and those with chain lengths shorter than ∼ C₂₀ are 'cracked' to lower alkanes and alkenes as has been reported previously by Suslick et al. In addition, sonication promoted a polymerization reaction which concentrated aromatic and nitrogen-containing compounds into insoluble sediments or gums. These were similar to those obtained from stability tests of diesel fuels and suggest that sonication may prove to be a useful method for the accelerated testing and prediction of long-term diesel stability.
