Embodiment 1
[0047] A kind of preparation method of coal tar suspended bed hydrocracking catalyst of the present invention, specifically implement according to the following steps:
[0048] Step 1. Grinding the semi-coke into a powder with a particle size of 10-100 μm; adding the semi-coke powder into distilled water and mixing evenly to obtain a suspension of semi-coke powder with a mass fraction of 20%;
[0049] Step 2, ferrous sulfate is added into distilled water, mix uniformly, obtain the ferrous sulfate solution that mass fraction is 20%;
[0050] Step 3, adding the ferrous sulfate solution into the blue charcoal powder suspension, and adjusting the pH to 6.0 with ammonia water, and then stirring at 50°C for 1 hour to obtain suspension a;
[0051] The stirring rate is 6000r / min;
[0052] The volume ratio of ferrous sulfate solution to blue charcoal powder suspension is 1:2;
[0053] Step 4, passing air into the suspension a obtained after step 3 to carry out oxidation reaction, whi...
