Embodiment 1
[0041] The residual oil and hydrogen mixed oil directly enter the residual oil hydrogenation pilot plant, and the catalytic cracking and refining are the same as in the comparative example. After mixing with supplementary hydrogen, it enters the residual oil hydrogenation reactor through the front feed port of the carbon removal agent bed, and the same The reaction was carried out according to the conditions in Table 3, and the reaction products were separated into gas, hydrogenated naphtha, hydrogenated diesel oil, and hydrogenated residue.
[0042] From Table 6, we can know that, compared with Comparative Example 1, the carbon deposit of the carbon residue removal agent in Example 1 is 9.5% lower, and the estimated operating period of the catalyst is 1 month longer than that of Comparative Example.

Embodiment 2
[0048] The residual oil and hydrogen mixed oil directly enter the residual oil hydrogenation pilot plant, and the catalytic cracking back to the refining oil is the same as that of the comparative example, and enters the residual oil hydrogenation reactor through the front feed port of the carbon removal agent bed, also according to the conditions in Table 3 The reaction is carried out, and the reaction product is separated into gas, hydrogenated naphtha, hydrogenated diesel oil, and hydrogenated residue.
[0049] From Table 6, we can know that, compared with Comparative Example 2, the carbon deposit of the carbon residue removal agent in Example 2 is 5.2% lower, and the estimated operating period of the catalyst is 1 month longer than that of Comparative Example.

Embodiment 3
[0055] Residual oil and hydrogen mixed oil directly enter the residual oil hydrogenation pilot plant, catalytic cracking and refining are the same as in the comparative example, enter the residual oil hydrogenation reactor through the front feed port of the desulfurizer bed, and react according to the conditions in Table 3 , The reaction product is separated into gas, hydrogenated naphtha, hydrogenated diesel oil, and hydrogenated residue.
[0056] Through Table 6, we can know that, compared with Comparative Example 3, the carbon deposit of the carbon residue removal agent in Example 3 is 6.5% lower, and the expected operating period of the catalyst is 1.5 months longer than that of Comparative Example.
