FHI----Diesel
hydroupgrading and isodewaxing
Features
of FHI
-
Combining
strengths of MCI and MHUG
-
High
flexibility and efficiency, via changing operation
modes and adjusting operating conditions, it is
possible to operate on
〔
Hydrofining (HDS and HDN)
〔
MCI (decrease density and increase cetane
number)
〔
Isodewaxing (lowing solidification point)
〔
Hydroupgrading (lowing T95 and increase naphtha
production)
-
Using
one catalyst or two catalysts in serial process.
-
Catalysts
have strong isomerization activity
-
High
activities of deep HDS, HDN, HDA and selective
ring-opening for straight run diesel and secondary
processing, isomerization for high solidification
paraffin and other distillates, and certain degree of
HC for heavy distillates.
Feedstock:
Straight
run diesel, straight run light VGO (LVGO), FCC diesel,
Coker diesel or their mixtures
Products:
Qualified
diesel products and some naphtha with low S/N contents and
high aromatics potential
Typical
operating conditions
Pressure:
6.0~18.0MPa
H2/Oil
(v): 400~1200
LHSV:
0.8~2.0h-1
Temperature:
340~430≧
FHI
technology has been applied in several domestic
refineries, the commercial results are shown in the
following tables. The data show that FHI technology can
greatly decrease S, N, polyaromatics contents and
solidification point of diesel product, and considerably
increase density, T95 and cetane number, and etc of
diesel.
