Medium-pressure
hydroupgrading technology（MHUG）
MHUG
was developed in late 1980 to improve cetane number and
stability of RFCC diesel, the typical application of which
is listed in below table.
Features
-
Combining
high activity HF catalysts and high selective
ring-opening activity HC catalysts
-
Single
stage one-through (SSOT) process
-
Produce
clean diesel with has high cetane number, low S
content and superior stability, some chemical naphtha
with low S/N and high aromatics potential, and
Aimed
at
Petrochemical
enterprises who not only have difficulties in producing
qualified diesel product, but need chemical naphtha and
feedstock of steam crackers for ethylene production.
