Embodiment 1
[0054] Step (1): The hydrocracking catalyst Z-863 is broken into small particles with a particle diameter of 50 μm, mixed with the 300° C.-450° C. fraction of coal tar, and the addition amount of the catalyst is 1.5% (weight). The 300°C-450°C fraction mixed with the catalyst is pumped into the fluidized bed reactor with a high-pressure pump, and mixed with hydrogen before the raw material enters the reactor. Raw material coal tar and hydrogen at a reaction temperature of 480°C, a pressure of 8MPa, and a liquid hourly space velocity of 0.5h -1 , Hydrogen oil volume ratio under the condition of 2000 to react. After gas-liquid and liquid-solid separation of the hydrocracking reaction product, hydrocracking product oil is obtained, and its properties are shown in Table 3.
[0055] Step (2): Mix the hydrocracking product oil obtained in step (1) with the 190°C-300°C fraction of coal tar at a ratio of 2:1, and use it as a fixed-bed hydrorefining reaction feed. The self-made cataly...
Embodiment 2
[0062] Step (1): Same as step (1) in Example 1.
[0063] Step (2): same as step (2) of Example 1, wherein the change is the loading volume of the catalyst, the purpose is to reduce the fluid linear velocity to investigate the reaction effect under different linear velocity. The self-made catalyst 1 was broken into 40-60 mesh catalyst particles, which were packed in a fixed-bed hydrogenation reactor with a loading volume of 70 mL. Reaction condition is the same as embodiment 1 step (2). After calculation, the linear velocity of oil flow under this condition is 1mm / s, and the actual linear velocity of hydrogen under the reaction pressure is 2.6mm / s.
[0064] Step (3): Fractional distillation of the hydrorefined product oil in step (2) to obtain fractions at 190-280° C., the properties of which are shown in Table 4.
[0065] As shown in Table 4, the density of the 190-280°C distillate of hydrorefined product oil is 0.832kg / m 3 , the volumetric calorific value is 35.17MJ / L, and...
