Embodiment
[0025] A kind of coker gasoline is used as raw material oil, and the properties of the raw material oil are shown in Table 1. From Table 1, it can be seen that the diene value of the raw material oil is 2.9gI / 100g, the actual colloid is 10mg / 100ml, and the sulfur content is as high as 6000μg / g, which is An inferior gasoline distillate. The feedstock oil is mixed with circulating hydrogen and enters the hydrogenation protection reactor, and then contacts the hydrogenation protection agent I and the hydrogenation protection agent II for reaction, wherein the filling volume ratio of the hydrogenation protection agent I and the hydrogenation protection agent II is 1:2 , the outlet effluent of the hydrogenation protection reactor directly enters the heating furnace to raise the temperature, and then enters the hydrogenation main reactor, and carries out the hydrofinishing reaction under the action of the hydrofinishing catalyst, and the reaction effluent enters the high-pressure sep...
