挂式-四氢双环戊二烯热裂解产物分布研究

研究了常压下, 温度为450～650 ℃, 停留时间为15.44～4.03 s条件下的JP-10 (挂式-四氢双环戊二烯)热裂解产物分布. 在相对较长的停留时间下, JP-10热裂解转化率对温度很敏感. 热裂解主要产物为甲烷、乙烯、丙烯、丁烯、丁二烯、环戊二烯、苯、甲苯、苯乙烯、环戊烯的乙烯基取代物及C5, C6异构体(戊二烯、环戊烯的甲基取代物、环己烯、己二烯和环戊二烯甲基取代物), 其中, C1～C4、环戊二烯、苯、甲苯、乙烯基取代环戊烯为初始产物.

Product Distribution of Thermal Cracking of exo-Tetrahydrodicyclopentadiene

Thermal cracking of JP-10 (exo-tetrahydrodicyclopentadiene) was investigated in an annular tubular reactor at atmospheric pressure, in the temperature range of 450～650 ℃ and space time range of 15.44～4.03 s. In a longer space time, the conversion of thermal decomposition of JP-10 was very sensitive to temperature. The major products were methane, ethylene, propylene, butylene, butadiene, cyclopentadiene, benzene, toluene, styrene, vinyl-substituted cyclopentene derivatives and C5/C6 isomers (pentadiene, methyl-substituted cyclopentene derivatives, cyclohexene, hexadiene and methyl-substituted cyclopentadiene derivatives), and the main primary products were determined to be C1～C4 compounds, cyclopentadiene, benzene, toluene and vinyl-substituted cyclopentene derivatives.
