Embodiment 1
[0042] use figure 1 The process flow shown is to produce low-condensation-point diesel by means of mixing and grading series processes. In Example 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 isomeric depointing catalyst and the hydrogenation depressing 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 hydrodegradation catalyst is FDW-3 catalyst, and the catalysts are Fushun Petroleum A commercial catalyst developed and produced by the Chemical Research Institute.
