The results demonstrate that presulfiding has an overall positive effect on catalyst performance in processing residues. The improvements are specifically in areas of significant interest in residue upgrading namely, conversion to distillates and asphaltenes reduction. The...

The catalyst Ufe test was conducted in the fixed-performance mode by increasing periodically reaction temperature to compensate for the activity loss. Unlike most of the residue upgrading processes which typically operate under HDS isoperformance, the target in this process was to keep the API gravity of the product constant, as this parameter is a good measure of the overall character of oils.
