    Novel Solvent Deasphalting Process by Vacuum Residue .

    The effect of the solvent deasphalting (SDA) process of vacuum residue (VR) blending with coal tar (CT) was studied, and the experimental conditions were optimized. The results revealed that the SDA process was improved by blending with coal tar. The yield of deasphalted oil (DAO) from VR blended with 10% CT was 2.02 wt % higher than that obtained from VR alone.
