Embodiment 1
[0036] A continuous stirring reactor with two tanks connected in series is used. Before the reaction, the reactor undergoes air replacement, leak detection operation, and hydrorefining catalyst is added, and the petroleum refining crude oil product A in the storage tank is pressed into the reactor with a high-pressure metering pump. Replace the air with nitrogen, repeat 3 times, and replace the air; use hydrogen for leak detection, close the valves, make the hydrogen pressure in the kettle a positive pressure (0.3MPa), turn on the reactor heater to preheat; let it stand for 5 minutes , check the airtightness of the reaction kettle; if there is no air leakage after the leak detection operation, you can add a hydrorefining catalyst with 5% of the mass of petroleum refining crude oil product A from the catalyst addition hopper, and the metal components are calculated as hydrogenation catalysts in terms of elements 5% of the mass of the refined catalyst, the metal component is Mo, ...

[0038] A continuous stirring reactor with two tanks connected in series is adopted. Before the reaction, the reactor undergoes air replacement, leak detection operation, and hydrorefining catalyst is added, and the petroleum refining crude oil G in the storage tank is pressed into the reactor with a high-pressure metering pump. Replace the air with nitrogen, repeat 5 times, and replace the air; use hydrogen for leak detection, close the valves, make the hydrogen pressure in the kettle a positive pressure (0.5MPa), turn on the reactor heater to preheat; let it stand for 5 minutes , check the airtightness of the reaction kettle; if there is no air leakage after the leak detection operation, you can add a hydrorefining catalyst with a mass of 3% of the petroleum refining crude oil product G from the catalyst addition hopper, and the metal components are calculated as hydrogenation catalysts in terms of elements. 3% of the mass of the refined catalyst, the metal component is W, and...
Embodiment 3
[0040] A continuous stirring reactor with two tanks connected in series is adopted. Before the reaction, the reactor undergoes air replacement, leak detection operation, and hydrorefining catalyst is added, and the petroleum refining crude oil product C in the storage tank is pressed into the reactor by a high-pressure metering pump. Replace the air with nitrogen, repeat 4 times, and replace the air; use hydrogen for leak detection, close the valves, make the hydrogen pressure in the kettle positive (0.4MPa), turn on the reactor heater to preheat; let it stand for 5 minutes , check the airtightness of the reaction kettle; if there is no air leakage after the leak detection operation, you can add a hydrorefining catalyst with a mass of 5% of the petroleum refining crude oil product C from the catalyst addition hopper, and the metal component is calculated as the hydrogenation catalyst in terms of elements. 20% of the mass of the refined catalyst, the metal component is Ni, and t...
