Abstract
A process which comprises a two-stage method for the preparation, from heavy residual oils, of a feedstock suitable for subsequent catalytic processing, such as for employment in FCC reactors. The firt process step comprises pentane deasphalting which results in substantial reduction of the refractory heavy metals present in the resid. The second step comprises removing any remaining metals by subjecting the treated heavy oil to a mild hydrocracking in the presence of a ZSM-5-type catalyst.
