催化重整装置原料中的碳六链烷烃(C6链烷烃)环化脱氢生成芳烃的反应速率很慢、转化率也很低，很容易发生异构化反应和加氢裂化反应，对重整装置的目标产品贡献很小，另外还会增加装置的能量消耗，因此碳六链烷烃不是理想的重整进料组分。通过调整重整装置预处理分馏塔的操作，可以控制重整原料的初馏点，尽可能减少原料中C6链烷烃的含量。本文利用KBC公司的Petro-SIM软件对某炼厂的重整装置建立了反应机理模型，研究改变重整进料C6链烷烃含量后，装置收率、操作条件和能耗的变化情况。研究结果显示，将加氢预处理的分离塔塔底温度提高6℃、重整进料的初馏点提高4.3℃，C5以上的液体收率能够提高0.75%，多产汽油0.9 ton/h，装置的总体能耗下降3260 MJ/h，取得了较好的效果。

Six carbon alkane as reformer feed components has slow reaction rate and low conversion rate, easily to occur isomerization reaction and hydrocracking reaction, small contribute to the target product, besides it will increase the unit energy consumption. So six carbon alkane is not an ideal reformer feed component. The content of C6 alkane in the feedstock can be minimized by changing the initial boiling point of the feedstock which can be controlled by adjusting the pretreatment fraction operation of reformer unit. By using KBC's Petro-SIM software, this research established a reformer reaction mechanism model studying on the variation of unit yield, operating conditions, the change of energy consumption after the content of C6 paraffin in the feedstock is changed. According to the optimizing result, when the bottom temperature of hydro treating separation column increased by 6 ℃ and the initial boiling point of the feedstock increased by 4.3 ℃, it resulted in increasing the liquid yield (C5+) by 0.75%and increasing gasoline production by 0.9 ton/h, and it realized the lowering overall energy consumption of the unit by 3260 MJ/h.
