Embodiment 1
[0028] The volume ratio of GUARD and HDM is constant, the HDS loading capacity is reduced by 50%, and the HDN loading capacity is reduced by 50%, which are replaced by HDCCR1-1 and HDCCR2-1 respectively, and the volume ratio of the two catalysts is 3: 5. location such as figure 2 shown.
Embodiment 2
[0030] HDM loading is reduced by 40%, HDS is maintained unchanged, HDN loading is reduced by 40%, and carbon removal catalysts HDCCR1-1 and HDCCR2-2 are used instead, the volume ratio of the two catalysts is 3: 2, and its position in the reactor like image 3 shown.
Embodiment 3
[0032] In Example 1, HDCCR1-1 is replaced by HDCCR1-2.
