Abstract

Thermal decomposition of two jet fuel model compounds, Decalin and Tetralin, was studied under near-critical and supercritical conditions. Under high-pressure supercritical conditions, the thermal decomposition of both compounds was dominated by isomerization reactions. This is different from the results obtained under low-pressure and high-temperature conditions where cracking reactions (for Decalin) or dehydrogenation reactions (for Tetralin) dominate. The major liquid products from Decalin were spiro[4,5]decane, Z-butylcyclohexene, 1-methylcyclohexene, 1-methylhydrindan, two octalins, and toluene. The cis-decalin was converted to trans-decalin as the reaction proceeded. The main liquid products from Tetralin were 1-methylindan and naphthalene with the former being the dominant product that was favored at high pressures.
