High-Pressure Thermal Decomposition of Tetrahydrotricyclopentadiene (THTCPD) and Binary High-Density Hydrocarbon Fuels of JP-10/THTCPD in a Tubular Flowing Reactor

Abstract

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 ...
