Hydroprocessing catalysts and methods for making thereof |
| abstract |
A method to prepare an improved catalyst feed to a system to upgrade heavy oil. The method comprises: providing a spent catalyst that has been used in a hydroprocessing operation has with a solid content ranging from 5 to 50 wt. % in soluble hydrocarbons and having less than 80% but more than 10% of original catalytic activity; removing at least 50% of the soluble hydrocarbons removed in a deoiling step; treating the deoiled spent catalyst with a treating solution containing at least one of plain water, a mineral acid, an oxidizing agent, and combinations thereof to reduce the concentration of at least one metal contaminant in the deoiled spent catalyst by at least 40%. After treatment, the treated deoiled spent catalyst is slurried in a hydrocarbon medium, and fed to the heavy oil upgrade system as part of the catalyst feed system with a fresh slurry catalyst. |
