Technologies for upgrading heavy residual oils for transportation fuels are becoming increasingly important. The asphaltenic Bottom Cracking (ABC) process developed by Chiyoda is one of the new upgrading technologies. ABC is the process of asphaltenes conversion by catalytic hydrotreating for petroleum heavy ends. The combination of ABC and solvent deasphalting (SDA) is the effective route for the complete conversion of asphaltenic bottoms. This report presents the characterizations of various products from Khafji vacuum residue by the pilot plant test of ABC combined with an SDA. One typical feature of product oils is to show good qualities (gravity: >20/sup 0/ API; metals: <3 wt ppm; asphaltenes: trace). The chemical structures of these product oils were investigated using a variety of techniques including LC, GPC, /sup 1/H and /sup 13/C NMR, and FI/FD-MS. In addition to the changes of physicochemical properties and chemical structures of product oils, the ABC reaction mechanism is described from the standpoint of chemical structural changes of SDA asphalts.
