| 从反应原理上看，热解反应是分子数显著增加，体积显著增大的过程，因此真空条件下有利于热解反应进行，且有利于一次热解反应产生的挥发物迅速从颗粒内部和表面离开，更容易实现“闪速热解”而利于液化工艺，限制二次裂解反应发生，特别是能降低卤化氢发生二次反应生成卤代烃的几率，提高热解油的产率 |

| From the reaction principle, pyrolysis reaction is a process that the number of molecules is increasing and the volume is rising remarkably. Therefore, pyrolysis reaction is easy to go forward under vacuum condition, and the volatile generated from the first pyrolysis reaction was leaving rapidly from the internal and surface of particles, "flash pyrolysis" is easy to realize which contributes to the liquefaction process and minimizes the secondary reactions and increases the yield of pyrolysis oil.（请参考一下，有些改动） |

| From the reaction principle, the pyrolysis reaction was a significant increase in number of molecules, significantly increasing the size of the process, so there is a vacuum under conditions conducive to the pyrolysis reaction, and is conducive to a hot reaction volatiles generated rapidly from the internal and surface particles to leave more easily achieve "flash pyrolysis" and in favor of liquefaction process, restrictions on the secondary cracking reactions happen, especially to reduce the occurrence of secondary reactions of hydrogen halide generated halohydrocarbon probability improve pyrolysis oil yield |

| From the reaction principle, pyrolysis reaction is the process of the number of molecules increasing and the volume ising remarkably. Therefore, vacuum condition is propitious to carry out the pyrolysis reaction and the volatile generated from the first pyrolysis reaction was leaving rapidly from the internal and surface of particles, "flash pyrolysis" is easy to realize which contributes to the liquefaction process and minimizes the secondary reactions and iimprove the yield of pyrolysis oil. |
