This paper focused on the thermal kinetics of crude vacuum residue (VR). Liaohe and Guanshu VR thermally reacted at 400,420,440,460,480 and 500℃ for reaction times ranging from 8~150 minutes in the presence of nitrogen undes total pressure 0.5 MPa. Gas, naphtha, middle fraction, coke and VR yeilds had been determined. A simple kinetic model including five lumped species had been set up for VR thermal conversion. The model parameters had been determined by the optimization method. The model calculation...

以大庆减压渣油和鲁宁管输减压渣油为原料,将其各自分离成饱和烃、轻芳烃、重芳烃、软胶质、硬胶质和沥青质6个族组分,以恒温盐浴的方法测试了各族组分在400~460℃下和5~90min内热裂解反应的产物分布;用简单的热裂解反应动力学模型对实验结果进行了关联,求取了热裂解反应模型的动力学参数。

Domestic gasoline consists of more than 75% high olefin contained FCC naphtha. Upgrading FCC naphtha will be an effective method for increasing the quality of the gasoline pool. The research showed that about 10% heaviest fraction of the FCC naphtha could be blended to LCO for hydrotreating and increased the diesel/gasoline ratio. The light fraction, about 50% of FCC naphtha could be processed by deep etherification, resulted in olefin content of the etherified naphtha decreased by 8%-10%, and its MON and oxygen...

Domestic gasoline consists of more than 75% high olefin contained FCC naphtha. Upgrading FCC naphtha will be an effective method for increasing the quality of the gasoline pool. The research showed that about 10% heaviest fraction of the FCC naphtha could be blended to LCO for hydrotreating and increased the diesel/gasoline ratio. The light fraction, about 50% of FCC naphtha could be processed by deep etherification, resulted in olefin content of the etherified naphtha decreased by 8%-10%, and its MON and oxygen content increased by 2 units and 1.2 %-1.4% respectively. The middle fraction was rich in aromatics potential content, which could be used as catalytic reforming feedstock.

我国车用汽油的组成中烯烃含量较高的催化裂化汽油占 75 %以上。对催化裂化汽油进行改质是解决催化裂化汽油自身的问题以提高车用汽油质量的有效措施。通过催化裂化分馏塔侧线将约 10 %的重质汽油作为柴油组分 ,不仅可减少催化裂化汽油的产量 ,还可以增产柴油 ,提高柴汽比。约占 5 0 %的轻质催化裂化汽油可进行深度醚化 ,醚化汽油中的烯烃含量降低 8%~ 10 % ,MON约增加 2个单位 ,氧含量增加 1.2 %~ 1.4%。中质催化裂化汽油馏分的芳潜较高 ,可作催化重整原料
