Effect of Oxygen-to-Vacuum Residue Ratio

Modeling of Processes and Reactors for Upgrading of Heavy Petroleum 

FIGURE 4.8 Effect of temperature, OJVR ratio, and Rj lVR ratio on carbon conversion atP = 11 bar. 

FIGURE 4.9 Effect of O2/VR on carbon conversion and synthesis gas composition (P = 11 

The amount of O2 (from chemical analysis) contained in the vacuum residue is important because it influences the point where the carbon conversion reaches 100%. If the vacuum residue contains more oxygen, the required O2/VR ratio will be lower to reach 100% conversion of carbon.
