Embodiment 1
[0016] Embodiment 1, the vacuum residue suspended bed hydrocracking catalyst is obtained according to the following steps: the first step, select pyrite, and the mass percentage of iron is 40% to 50% of pyrite as raw material; In the second step, the pyrite raw material selected in the first step is primary ground to a particle size of less than or equal to 200 mesh to obtain a vacuum residue suspended bed hydrocracking catalyst.
Embodiment 2
[0017] Embodiment 2, this vacuum residue suspended bed hydrocracking catalyst is obtained according to the following steps: the first step, select pyrite, the mass percent composition of iron is 40% to 50% and S: the mol ratio of Fe The pyrite of 1.6 to 2.0 is used as a raw material; in the second step, the pyrite raw material selected in the first step is primary ground to a particle size of less than or equal to 200 mesh to obtain a vacuum residue suspended bed hydrocracking catalyst.
Embodiment 3
[0018] Embodiment 3, the vacuum residue suspended bed hydrocracking catalyst is obtained according to the following steps: the first step, select pyrite, and use the pyrite whose mass percentage of iron is 40% to 50% as raw material; In the second step, the pyrite raw material selected in the first step is primary ground to a particle size less than or equal to 200 mesh to obtain a vacuum residue suspended bed hydrocracking catalyst; in the third step, the vacuum residue suspended bed The hydrocracking catalyst is deeply ground to a particle size of 100nm to 1μm to obtain a high-quality vacuum residue suspended bed hydrocracking catalyst.
