外文摘要：The thermal upgrading of two residual oils with different characteristics was studied in a laboratory-scale continuous delayed coking unit. The goal was to investigate the influence of the process variables 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.
