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.
