Catalyst demetallization by converting the metal poisons to a sulfur containing metal compound having a defined low amount of sulfur |
| abstract |
A process for the removal of metal poisons such as nickel, iron and/or vanadium from a hydrocarbon conversion catalyst which includes the step of contacting the catalyst with a sulfur-containing compound to convert at least a portion of the metals on the catalyst to a sulfur-containing metal compound. The weight % sulfur on the thus treated catalyst is controlled to about 40-90%, preferably about 40-75%, of the weight % of the total nickel, vanadium and iron on the catalyst. Preferably, the sulfur-containing compound is hydrogen sulfide in admixture with a reducing gas such as hydrogen and/or carbon monoxide. This step facilitates metal removal in subsequent processing steps. |
