China
government
has
speeded
up
the
pace
to
update
theregulations
on
transportation
fuels
in
recentyears.
According
to
the
Environmental
Protection
Agency
of
China,
by
the
end
of
2010,
the
standard
China
IV
thatis
almost
equivalent
to
EuroIV
will
be
enacted,
and
then
China
V
will
follow
very
quickly.
Generally
speaking,
producing
gasoline
with
low
olefin
and
sulfur
contents
will
be
an
inevitable

difficulty
for
most
of
the
Chinese
refineries
to
producing
clean
gasoline
lies
in
that
FCC
gasoline
takes
ashare
of
about
80%in
commercialgasoline
pool.
In
typical
FCC
gasoline,
sulfur
content
is
as
high
as
300-600
ppm,
olefin
content
is
as
high
as
40%!
So,
reducing
the
sulfur
andolefin
contents
of
FCC
gasoline
is
the
main
focus
of
clean
gasoline
productions.硫我国CC汽油的组成烯烃芳烃300~600

These

on
the
above
discussion,
we
can
conclude
that
the
difficulty
inupgradingFCC
gasoline
lies
in
the
contradictions
between
gasoline

and
process
requirements.汽油质量标准 工艺要求深度加氢脱硫矛盾保持辛烷值降烯烃矛盾保持辛烷值提高辛烷值矛盾汽油产率催化剂的稳定性CC汽油加氢改质技术开发的难点To
overcome
the
above
difficulty,
we
developed
a
combined
process
consisting
of
a
hydroisomerization
and
aromatization
catalyst
for
reducingolefincontent
and
recovering
octane
and
a
selective

Our
aim
is
to
develop
a
process
for
producing

The
key
is
to
maximize
catalyst

aromatizationactivity
to
transfor
olefins
into
two-
or
three-branched
isoalkanes
and
aromatics
while
minimizing
the
saturation
of
olefins.
This
requires
that
thecatalyst
to
have
suitable
acidity
to
provide
both
hydroisomerization
and

and

has

SAPO-11
that
has

we
obtained
acompsoite
catalyst.
As
expected,
this
catalyst
shows
good
isomerization
and
aromatizationactivity,
but
suffers
fromquick
deactivation
because
ofthe
too
strong
acidity
of
the
ZSM-5
and
weaker

on,
we
developed
a
combined

to

with

two
methods,

It
decreases
the
olefincontent
of

and

is
as

as
98%.
Moreover,
these
results
are
achieved

However,
The
desulfurization
ratio
is
not
so
high,
with
the
sulfur
content
of
the
upgraded
gasoline
being
as
high
asregulated
by
China
IV.So,
the
question
how
to

arises.饱和烃烯烃芳烃硫(ppmw)RON产率

we
know,
olefin

hydrodesulfurizationreactions
take
place
on

particles
supported
on
alumina.
The
rim
sites
areactive
for
both
hydrogenation
ofolefins
and
hydrodesulfurization
of
sulfur-containing
compounds,
while
edge
sites
are
only
active
for
HDS.Obviously,
the
route
to
achieve
highly
selective
HDS
is
to
maximizing
the
ratio
of
edge
sites.
Increasing
the
stacking
of
metal
sulfide
is
good
forselectivity,
but
gives
rise
to
lower
activity;
increasing
the
dispersion
of
metal
sulfide
gives
highactivity,
but
results
in
lower
selectivity.
This
suggeststhat
to
achieve
both
higher
desulfurizationratio
and
higher
selectivity,
there
must
be
a
compromise

FCC

cannot
give
satisfactory
results?By
analyzing
the
distributions
of
sulfur
and
olefins
in
the
full
range
FCC
gasoline,
we
found
that
sulfur
mainly
exists
in
the
heavier
fraction
with
itsinitial
boiling
point
higher
than
70
oC,
while
the
lighter
fraction
with
its
boilingpoint
belowis
almost
sulfur
free.
This
means
that
it
is
unnecessary
tohave
the
light
fraction
hydrotreated.
Otherwise,
agreat
loss
in
RON
will
happen.However,
for
the
heavy
fractions,
the
olefin
content
is
comparable
to
that
regulated
by
China
IV,
but
its
sulfur
content
is
very
high.
Of
course,
itmust
be
deeply
desulfurzied
to
remove
the
excessive
sulfur.
However,
this
will
cause
theObviously,
to

we
need
to
split

on
the
above
discussion,
finally
we
proposed
a
FCC
hydro-upgrading
process.
The
first
step
is
to
split
full
range
FCC
gasoline
intoalightfraction
and
heavier
fraction.
For
the
former,
no
further
treatment
is
needed.
However,
the
heavier
fraction
should
be
treated
using
the
selectiveHDS
catalyst
in
the
first,
and
thenfurther
treated
using
the
hydroisomerization
and
aromatizationcatalyst.
Finally,
the
untreated
lighter
fraction
andthe
treated
heavier
fraction
are
blended.Here,
we
must
point
out
that
this
process
configurationis
different
from
the
commercial
processes
