Abstract: In this article, effects of hydrogen partial pressure and reaction temperature on removal of 8 kinds of polycyclic aromatic hydrocarbons(PAHs) by hydrogenation was studied by naphthenic vacuum gas oil. The results showed that because of stereohindrance effect of BaP and BeP, PAHs in naphthenic vacuum gas oil were difficult to remove by hydrofining process. The higher the hydrogen partial pressure, the easier it was to remove large space steric hindrance of PAHs. Under the condition of hydrogen partial pressure 4~10 MPa, the effect of hydrogen partial pressure on the extreme value point of the transformation of dynamic control to thermodynamic control was not obvious. However, Under high pressure, the effect of hydrogen partial pressure was obvious, and the hydrogenation process of the PAHs was controlled by dynamic control when the hydrogen partial pressure was 15 MPa.

摘要: 以环烷基减压馏分油为原料,考察了氢分压和反应温度对加氢脱除8种多环芳烃的影响。结果表明, 由于BaP和BeP空间位阻较大,其脱除率高低直接影响8种多环芳烃脱除率的高低;同时,提高氢分压有利于脱除空间位阻大的多环芳烃;氢分压为中、低压(4~10MPa)时,8种多环芳烃加氢脱除过程由动力学控制向热力学控制转化的极值点位置受氢分压影响较小,而在高压条件下受氢分压影响较为明显,当氢分压达到15 MPa时,8种多环芳烃的加氢脱除过程主要由动力学控制。
