考察了ZSM-5分子筛催化高密度碳氢燃料JP-10的裂解情况。与热裂解相比,分子筛催化可显著提高裂解转化率,主要产物有甲烷、乙烷、乙烯、丙烷和丙烯,以及苯和苯的同系物等。在较高温度时,由于氢转移反应,产物中出现了茚、萘等低氢碳比化合物,会影响燃料的燃烧性能,应用时需要根据性能要求在高裂解转化率与低芳烃收率之间进行权衡。通过裂解产物分析结合量子化学计算,探讨了JP-10催化裂解的可能历程,并对实验结果进行了解释。

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.
Key words: High-density hydrocarbon fuel, Catalytic cracking, JP-10, ZSM-5
