Abstract
Embodiments of the present disclosure are directed to a process for modifying catalysts comprising introducing a precursor agent and hydrogen gas to a conversion reactor; contacting the precursor agent with a conversion catalyst in the conversion reactor, thereby producing an active agent; introducing the active agent to a production reactor; and contacting the active agent with a hydroprocessing catalyst in the production reactor, thereby producing a modified hydroprocessing catalyst.
Claims19
A process for modifying hydroprocessing catalysts, the process comprising:
- introducing a precursor agent to a conversion reactor;
- introducing hydrogen gas into the conversion reactor;
- contacting the precursor agent with a conversion catalyst in the conversion reactor, thereby producing an active agent;
- introducing the active agent to a production reactor;
- contacting the active agent with a hydroprocessing catalyst in the production reactor, thereby producing a modified hydroprocessing catalyst;
- wherein:
- the precursor agent is introduced to the conversion reactor as a liquid, and
- the active agent is introduced to the production reactor as a gas;
- contacting the hydroprocessing catalyst with a hydrocarbon feedstock in the production reactor to produce an outlet;
- and
- separating the outlet of the production reactor into a liquid effluent and a gaseous effluent.
