Embodiment Construction
[0017] The solutions and effects of the present invention will be described in more detail below in conjunction with the drawings and embodiments.
[0018] like figure 1 As shown, in the following preferred embodiments of the present invention, the purified washed oil 1 is first mixed with hydrogen 2 and enters the hydrogenation reactor 3 to obtain the hydrogenated oil 4 and enters the high-pressure separator 5 for gas-liquid separation, and the obtained gas 6 is recycled after being pressurized by the circulating hydrogen compressor 7, and the separated liquid 9 enters the stripping tower 10 (or fractionating tower) for fractional distillation according to the amount of gasoline (naphtha) to obtain gas products, gasoline (naphtha) 11, Diesel 12.
[0019] Table 1 lists the properties of the washing oil raw material used in the following examples 1-4.
