在电加热管式反应器中，对四氢三环戊二烯（THTCPD）和JP-10/THTCPD二元高密度烃燃料在500-660℃、4.0 MPa条件下的高压热分解进行了研究。对THTCPD在高温、高压、低停留时间下进行分解，分析其对产物的影响。JP-10/THTCPD热解实验结果表明，THTCPD的热解比JP-10的热裂解要容易得多，并且JP-10的加入可以显著促进THTCPD的热解，当与50%的JP-10混合时，THTCPD的转化率在660℃时可提高80%。关于JP-10/THTCPD热解的途径和机理，可能的原因是THTCPD分解产生的自由基通过吸h反应促进了JP-10的分解。相应地，JP-10热解过程中产生的大量新自由基…
High-pressure thermal decomposition of tetrahydrotricyclopentadiene (THTCPD) and binary high-density hydrocarbon fuels of JP-10/THTCPD were investigated at 500–660 °C and 4.0 MPa in an electrically heated tubular reactor. The decomposition of THTCPD under high temperature, high pressure, and low residence time was conducted to analyze their effects on the products. The experimental results of JP-10/THTCPD pyrolysis show that the THTCPD pyrolysis is greatly easier than the thermal cracking of JP-10, and the addition of JP-10 can significantly promote the THTCPD pyrolysis, which is evidenced by the fact that THTCPD conversion increases up to 80% at 660 °C when blended with 50% JP-10. It may be ascribed to possible reason about the pathway and mechanism of JP-10/THTCPD pyrolysis is that the free radicals generated by the decomposition of THTCPD help to promote the decomposition of JP-10 via H-abstraction reactions. Correspondingly, a large number of new free radicals generated from the JP-10 pyrolysis could ...
