摘要：

The thermal upgrading of two residual oils with different characteristics was studied in a labora- tory-scale continuous delayed coking unit.The goal was to investigate the influence of the process vari- ables such as temperature,reaction time and additive on liquid yield and products distribution.A maximum liquid yield of 73% was achieved compared to 69% with the commercial unit.This yield was even increased to 75% under the effect of an additive.The fractionation of liquid oil by simulated vacuum distillation showed a high yield of diesel(46.9%),compared to 28% for the commercial unit.
