[0018] The embodiment of this solution is described in conjunction with the flow chart of the device to further illustrate the present invention.
[0019] combine figure 1The coal tar raw material 1 is put into the cracking and fractionating tower 2, and the heavy component oil 3 with a temperature greater than 360°C is fractionated and sent to the cracking heating furnace 6 for recycling, and the light component oil 4 with a fractional distillation temperature lower than 360°C is sent to the hydrofining process, The heavy component oil 3 preheated to 320-420°C is mixed with hydrogen 5 and sent to the cracking heating furnace 6, heated to 400-480°C and entered into the hydrogen cracking towers 7 and 8 for cracking reaction. During operation, the reaction pressure of the cracking tower is controlled to 0.28MPa, and the temperature is controlled at 450~550°C. The ratio of hydrogen to oil is controlled as follows: Case 1 is 0; Case 2 is 20:1; Case 3 is 40:1. The two hydrocracki...
