Example Embodiment
[0032] Example 1
[0033] This embodiment provides a residue hydrogenation catalyst, and the raw materials used to prepare the residue hydrogenation catalyst include:
[0034] Modified kaolin carrier, 70 parts by weight;
[0035] Active metal Mo, 3 parts by weight (as Mo 2 O 3 meter);
[0036] Activated carbon, 19 parts by weight, the specific surface area of the activated carbon is 500m 2 / g, the pores with a radius of 80-120nm on the activated carbon account for 55% of the total pores;
[0037] Wherein, the carrier is prepared by the following method:
[0038] (1) Weigh the kaolin raw soil and the pore expander sodium carbonate and mix them uniformly, control the mass ratio of the kaolin raw soil to the pore expander to 1:6, and carry out the process under nitrogen at a temperature of 600°C Reaming treatment 3h;
[0039] (2) Use 15% hydrochloric acid to pickle the product of step (1) twice, and then wash it with water after the pickling is completed; after the water washing is comple...
