摘要/Abstract

摘要： 利用小型固定流化床实验装置考察了蓬莱与达里亚减压馏分（VGO）的催化裂化反应性能，研究了反应温度、剂油比、空速和水油比对产物分布的影响。结果表明：轻油收率随反应温度与剂油比的减小以及空速与水油比的增大而增大；在反应温度500 ℃、剂油质量比6、质量空速20 h-1和水油质量比0.08的工业操作条件下，蓬莱VGO的转化率为92.18%，轻油收率为62.62%，总液体收率为81.71%，达里亚VGO的转化率为94.14%，轻油收率为64.14%，总液体收率为82.63%；在反应温度490 ℃、剂油质量比5、质量空速25 h-1和水油质量比0.10的较优操作条件下，蓬莱VGO的转化率为91.98%，轻油收率为66.54%，总液体收率为84.09%，达里亚VGO的转化率为93.59%，轻油收率为70.98%，总液体收率为84.86%。总体来说，达里亚VGO的裂化性能优于蓬莱VGO。

Abstract: The catalytic cracking performance of Penglai and Daliya vacuum gas oils (VGO) was investigated in a fixed fluidized bed. The influence of reaction temperature (T), catalyst to oil weight ratio (C/O), weight hourly space velocity (WHSV) and steam to oil weight ratio (S/O) on the distribution of the cracking products was studied. The yield of light oils increases with decreased reaction temperature and C/O and with increased WHSV and S/O. At the industrial operating conditions (T=500 ℃, C/O=6, WHSV=20 h-1, S/O=0.08), the conversion, light oil yield and total liquid yield of Penglai VGO reach 92.18%, 62.62% and 81.71%, respectively, and those of Daliya VGO are 94.14%, 64.14% and 82.63%, respectively. At the optimal operating conditions (T=490 °C, C/O=5, WHSV=25 h-1, S/O=0.10), the conversion, light oil yield and total liquid yield of Penglai VGO is up to 91.98%, 66.54% and 84.09%, respectively, and those of Daliya VGO are 93.59%, 70.98% and 84.86%, respectively. It is concluded that the cracking performance of Daliya VGO is better than that of Penglai VGO.
