The catalytic cracking of JP-10, one kind of high-density hydrocarbon fuel, over ZSM-5 molecular sieve was investigated. Compared with thermal cracking of JP-10, the conversion ratio of catalytic cracking under the same conditions was evidently heightened. The predominant products of catalytic cracking are methane, ethane, ethylene, propane, propylene, benzene and it’s homologues. It is found that indene and naphthalene were produced because of the hydrogen transfer reaction at high temperatures, which will affect the combustion property of JP-10. High conversion ratio and low content of aromatics could not be obtained simultaneously. In combination of the determined products and the quantum calculation, the reaction mechanism of the catalytic cracking of JP-10 was discussed. The results could be reasonably explained from the proposed mechanism.
