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

trend.生产清洁汽油的意义欧III2000欧IV2005国III2007国IV2013(预测)国V(预测)硫(ppmw)<150<50<150<50<10苯(v%)<1.0<1.0<1.0<1.0<1.0芳烃(v%)<42.0<35.0<35.0<35.0<35.0烯烃(v%)<18.0<18.0<25.0<28.0<25.0氧(m%)<2.7<2.3<2.7<2.3<2.3清洁汽油标准的必然发展趋势—低烯烃和超低的硫含量The

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

processes

can

be

into

two

on

the

above

discussion,

we

can

conclude

that

the

difficulty

inupgradingFCC

gasoline

lies

in

the

contradictions

between

gasoline

qualityspecifications

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

hydrodesulfurizationcatalyst.

Our

aim

is

to

develop

a

process

for

producing

from

with

high

olefin

to

of

without

causing

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

activity

and

pore

large

we

obtained

As

expected,

this

catalyst

shows

good

isomerization

and

aromatizationactivity,

but

suffers

fromquick

deactivation

because

ofthe

too

strong

acidity

of

the

ZSM-5

and

weaker

because

of

on,

we

developed

decreases

the

However,

The

is

not

so

high,

with

the

of

the

as

high

asregulated

by

the

question

how

to

arises.饱和烃烯烃芳烃硫(ppmw)RON产率

we

know,

olefin

saturation

and

hydrodesulfurizationreactions

take

place

on

metal

sulfide

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

between

and

direct

upgrading

of

FCC

gasoline

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

to

achieve

we

need

to

split

a

and

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

configurationis

different

from
