Hydrofining
technology
for straight run diesel and secondary
processing diesel
Typical applications
Case
1
Operating conditions: HPP 6.0Mpa, LHSV
2.0~3.5h-1 and H2/Oil (v)
300~500:1 and temperature 340~360℃
Catalyst: FH-98
Feedstock: Secondary
processing diesel (FCC LCO or Coker diesel) original
from Daqing, Lu-Ning Pipeline, Sheng li and Mid-East
crudes
Product diesel: S, Iodine number, Gum, Oxidation
stability, Color and other specifications all meet
national quality standard for light diesel.
Case
2
Operating conditions: HPP 3.2~3.4Mpa, LHSV
2.0~3.0h-1 , H2/Oil(v) 200~350:1
and temperature 350~360℃
Catalyst: FH-5A
Feedstock: straight run
diesel of Mid-East crudes or mixed oil with FCC diesel
and Coker diesel
Product diesel: S content decreased
from around 10000μg/g to ≤500μg/g, meeting national S quality
standard for city light diesel.
Advantages: Improving storage stability of secondary
processing diesel, good sulfur removal performance, mild
operating conditions, low operating costs.
Disadvantages: Limited cetane number
improvement, Cannot decrease much of diesel’s
aromatics.
