Embodiment 1
[0043] use figure 1 The process flow shown is to produce low-condensation-point diesel oil by using gradation series and mixed packing process. In embodiment 1, two hydrogenation reaction zones connected in series are included, and in the composite bed of the depointing catalyst in each reaction zone, the mixing volume ratio of the hydrogenation modified heterogeneous depointing catalyst agent and the hydrogenation depreciating catalyst is 1: 4. The hydrogenation modification catalyst used in Example 1 is FC-18 catalyst, the hydrogenation modification isomerization depreciation catalyst is FC-14 catalyst, and the hydrogenation modification catalyst is FDW-3 catalyst, and the catalysts are Fushun Commercial catalyst developed and produced by Petrochemical Research Institute.
