Thermal cracking of Venezuela vacuum residue (VR) was carried out in a batch reactor system. The thermally cracked resid was diluted with toluene and was subject to antisolvent (SAS) separation using n-pentane at the liquid and supercritical state in a continuous SAS apparatus. The SAS-derived liqui...
