Embodiment 1
[0042] The trade name of the hydrogenation catalyst used in Example 1 is RVS-420, both of which are produced by Sinopec Catalyst Company.
[0043] Example 1
[0044] A high-sulfur vacuum gas oil fraction from the Middle East is used as a feedstock oil, mixed with reactor effluent and hydrogen, and the mixed material is introduced into a reactor equipped with a hydrofining catalyst. The raw material oil undergoes deep hydrodesulfurization reaction under the action of hydrorefining catalyst. The reaction conditions are: reaction temperature 380°C, total liquid hourly volume space velocity 1.68h -1 , the pressure of the reaction system is 8.0MPa, the volume ratio of hydrogen to liquid under standard conditions is 20-30v / v, the catalyst is 3 beds in the reactor, and a mixer is arranged between the two beds, and the reaction The material is mixed again with fresh hydrogen. The reactor effluent enters the high-pressure separator and is fed with hydrogen for stripping. The liquid p...
Embodiment 2
[0049] A mixture of Middle Eastern high-sulfur vacuum gas oil fraction and coker gas oil is used as feed oil, mixed with reactor effluent and hydrogen, and the mixed material is introduced into a reactor equipped with a hydrogenation catalyst. The reactor is filled with a supported hydrorefining catalyst RN-32V, which is produced by Sinopec Changling Catalyst Factory.
[0050] The raw material oil undergoes deep hydrodesulfurization reaction under the action of a hydrorefining catalyst. The reaction conditions are: reaction temperature 363°C, fresh raw material oil liquid hourly volume space velocity 1.62h -1 , the pressure of the reaction system is 8.0MPa, the volume ratio of hydrogen to liquid under standard conditions is 20-30v / v, the catalyst is 3 beds in the reactor, and a mixer is arranged between the two beds, and the reaction The material is mixed again with fresh hydrogen. The reactor effluent enters the first high-pressure separator and is fed with hydrogen for stri...
Embodiment 3
[0053] A mixture of Middle Eastern high-sulfur vacuum gas oil fraction and deasphalted oil is used as feed oil, mixed with reactor effluent, hydrogen, and the mixed material is introduced into a reactor equipped with a hydrogenation catalyst. The reactor is filled with a supported hydrorefining catalyst RN-32V, which is produced by Sinopec Changling Catalyst Factory.
[0054] The raw material oil undergoes deep hydrodesulfurization reaction under the action of a hydrorefining catalyst. The reaction conditions are: reaction temperature 380°C, fresh raw material oil liquid hourly volume space velocity 1.80h -1 , the pressure of the reaction system is 14.0MPa, the volume ratio of hydrogen to liquid under standard conditions is 20-30v / v, the catalyst has 3 beds in the reactor, and a mixer is provided between the two beds, and the reaction The material is mixed again with fresh hydrogen. The reactor effluent enters the first high-pressure separator and is fed with hydrogen for str...
