Description
Technical field
The present invention relates to the side for manufacturing unsaturated hydro carbons by the raw material using saturated hydrocarbons as principal component using zeolite catalyst
Method.
Background technology
The monocyclic virtue such as the light alkene such as ethene, propylene, butylene and butadiene class and benzene, toluene, ethylbenzene and xylene
The fragrant same clan is the important foundation chemical raw material for the backbone to form petro chemical industry.Manufacture the raw material master of these basic chemical feedstocks
If the naphtha of the straight run light fraction as crude oil.
In these basic chemical feedstocks, on the light alkene class such as ethene, propylene, butylene and butadiene, following manufacture:Will
Belong to the light naphtha of the relatively low component of boiling point in naphtha as raw material, by naphtha cracker complex, steaming
Vapour is thermally decomposed (steam cracking) in the case of coexisting with more than 800 DEG C of high temperature.In addition, the thermal decomposition of light naphtha
In, in addition to light alkene class, go back the fragrant same clan such as coproduction benzene, toluene, ethylbenzene, xylene.But to these fragrant same clans,
The known general manufacture for using cut corresponding using the heavy naphtha with being rich in higher boiling component than light naphtha as raw material
Method, this is more efficient manufacture method compared with the method manufactured by light naphtha.From this viewpoint, it may be said that
To the decomposition product of light naphtha, it is desirable to reduce aromatic component and improve the ratio of light alkene class as far as possible.
If pay close attention to the Demand trend in recent years of light alkene class, headed by polypropylene, isopropylbenzene, propylene oxide etc. third
The demand of ene derivative is expanding.At present, the growth for growing beyond ethylene requirements of propylene demand, it is believed that the propylene from now on
It will further speed up with the difference of the demand growth of ethene.
On the other hand, as naphtha principal component rudimentary saturated hydrocarbons, since its reactivity is low, be used as stone brain
The decomposition temperature of oil-breaking is, it is necessary to which more than 800 DEG C of high temperature, the decomposition temperature scope that can obtain the yield of good economy performance have
Limit.In general, more carrying out naphtha pyrolysis in high temperature, the yield compared to the ethene of propylene is higher, the height more than 800 DEG C
Warm area, the propylene/ethylene ratio in product are 0.6~0.7 or so.Within this temperature range, can not significantly change propylene/
Ethylene ratio, accordingly, it can be said that with existing naphtha cracker complex, the selectivity production of propylene is extremely difficult.
In conclusion the product distribution in thermal decomposition depends on decomposition temperature, it is taken as that existing naphtha pyrolysis
Device is difficult to the variation for neatly tackling the equilibrium of supply and demand of each component.In addition, centered on the natural gas producing nations such as the Middle East,
Rapidly promote raw material conversion, using price compared with naphtha low-down ethane as raw material, second that cost competitiveness is high
Alkene is coming into the market.Therefore, the naphtha cracker complex in the Asia headed by the country must not be answered without production adjusting etc.
To these situations.In the case where so forcing, the naphtha for looking forward to product can be controlled to be distributed according to supply and demand decomposes work
Skill, for this reason, as promising technology, discloses the contact decomposition technique using acid form catalyst (for example, patent document
1).The technology can reduce consumed energy, Jin Erneng compared with belonging to the existing naphtha cracker complex of more energy-dissipating type equipment
It is enough to reduce the carbon dioxide (non-patent literature 1) for decomposing and largely discharging with naphtha.
In the contact decomposition technique of the rudimentary saturated hydrocarbons such as disclosed naphtha, mesopore zeolite, wherein particularly ZSM5
Representative MFI zeolites, when generating light alkene class and aromatic compound species with excellent performance.Utilize these skills
Art, reaction temperature can be reduced to less than 700 DEG C, and the selectivity of propylene and the ratio of propylene/ethylene can be significantly increased.This
Outside, by reducing reaction temperature, the growing amount of the methane relatively low as the value of chemical raw material can also be suppressed.However, these
Public technology can not also be known as the technology of the ripe degree to the thermal decomposition alternatively both deposited.
In order to make the contact decomposition technique using the rudimentary saturated hydrocarbons such as the naphtha of zeolite reach can be practical water
Put down, it is necessary to significantly extend catalyst life.In addition, catalyst life is common in the reaction process using zeolite catalyst
Logical huge problem, especially, reaction condition is harsher, can more cause significantly reducing for catalyst performance.The drop of catalyst performance
It is low to cause the yield of purpose product to decline, cause the load increase to refining step etc. to be asked because of the change of product distribution
Topic.The main reason for performance of zeolite catalyst reduces, it is believed that be known as thin caused by the carbonaceous accumulation of coke (coke)
The Acidity caused by aluminium component disengaging in hole occlusion and the crystallization of zeolites skeleton caused by contact with high-temperature steam etc.
Disappearance.
The generation of coke, it is believed that be under harsh reaction condition, pass through the polymerization of such as light alkene, cyclisation, virtue
Caused by side reaction as fragrant race carries out in proper order.On the other hand, zeolite catalyst is characterized in that, is had from knot
The clear and definite pore of size of crystal structure, the acid site in pore carry out the reaction of shape selective.Therefore, it is particularly, if
Using the zeolite catalyst without big pores more than 12 yuan of rings, then due to space in terms of limitation, in pore, can cause
The gradualness side reaction of coke generation is also restrained.However, in zeolite, in the pore appearance of the limitation from pore shape
Face, also there are acid site in certain proportion, it is believed that thus because of the progress of non-selective reaction the generation of coke can be caused (non-
Patent document 2).It is the reaction that carries out at high temperature to be decomposed due to the contact of the lower hydrocarbons such as naphtha, thus such because of coking
The problem of performance reduction of zeolite catalyst caused by (U ー キ Application グ) is serious, in terms of practicality, suppresses the skill of coking
Art becomes key point.
In the contact converting reaction process of the saturated hydrocarbons carried out at high temperature, it is however generally that, catalyst due to coking, its
Activity reduces, but known by adding oxidizing gas in the feed, can inhibit coke generation, extends catalyst life.As
Oxidizing gas, uses vapor, carbonic acid gas etc..
For example, the propylene manufacture (non-patent literature 3) of dehydrogenating propane reaction is being carried out using Pt catalyst, is being catalyzed using Fe
Agent is carried out in the techniques such as the styrene manufacture (non-patent literature 4) of ethylbenzene dehydrogenation reaction, and water is used by adding in the feed
Steam.Vapor plays the effect as oxidizing gas under the high temperature conditions, it is believed that in catalyst layer, except key reaction
Outside, promote the removal of coke and precursors of coke produced by steam reforming reaction, suppress coking.
On the other hand, it is known that zeolite catalyst is generally contacted with steam under the high temperature conditions, therefore is absorbed in permanent work
Property deterioration.The permanent activity deterioration is to combine hydrolysis, Al components by the Al-O-Si in zeolitic frameworks under the high temperature conditions
Depart from, Acidity disappears and produces.Therefore, in order to use vapor conduct in the pyroreaction technique for use zeolite catalyst
Oxidizing gas is, it is necessary to the zeolite catalyst for the processing for being improved steam patience using applying.
So far in the contact decomposition technique of the rudimentary saturated hydrocarbons such as disclosed naphtha, as the common zeolite catalyst of use
Technique, it is necessary to so-called more than 600 DEG C harsh of high temperature.However, it is difficult to suppress notable due to that can produce under this condition
Coking, therefore vapor is made an addition in raw material, relaxes coking.On the other hand, the contact of the rudimentary saturated hydrocarbons such as naphtha
In decomposition reaction technique, catalyst needs that reaction is repeated, is regenerated in long-time service, due to the addition of vapor, urges
Agent can be exposed to high-temperature vapor for a long time, therefore easily cause active deterioration.In addition, the manufacture of high-temperature vapor is required
The reason for specific energy consumption that energy consumption becomes technique entirety is deteriorated.In conclusion from practicality and Eco-power viewpoint
Apparently, it is necessary to suppress as far as possible low the additive amount of vapor.
It is disclosed to use the zeolite catalyst for improving steam patience, vapor is added in the feed, implements naphtha etc.
The example that the contact of rudimentary saturated hydrocarbons is decomposed.In patent document 2, the ZSM5 catalyst containing P is used, in patent document 3
Used the ZSM5 catalyst containing P, Ca, La, on n-hexane decomposition reaction, implement 48 it is small when more than continuous operation.
However, to any example, from the viewpoint of practicality and economy, it cannot be said that be the continuous operation under reality condition.
In addition, also disclose and add vapor in the feed to carry out the contact of the rudimentary saturated hydrocarbons such as naphtha decomposition
The example (patent document 4 and 5, non-patent literature 5) of reaction, but to any example, do not implement the reality considered from practical face
Property continuous operation.
It is disclosed in steam reforming reaction, using the zeolite catalyst added with active metal class, is steamed in water
Implement the technology of the contact decomposition reaction of the rudimentary saturated hydrocarbons such as naphtha under gas adding conditional.In non-patent literature 6, in steam weight
In whole reaction, using with the addition of the ZSM5 of active Ni and Ru as catalyst, to the lightweight under vapor adding conditional
Naphtha contacts decomposition reaction, continuous operation when progress 10 is small.However, from practicality and Eco-power viewpoint, it is impossible to
Say it is the continuous operation under reality condition.
In non-patent literature 7, the ZSM5 added with active Pd is used in steam reforming reaction as catalyst,
Implement naphtha contact under vapor adding conditional to decompose.In the prior art document, in order to improve reactivity, except water steams
Beyond gas, methanol is also added in raw material naphtha, implements reaction, but conversion ratio at 635 DEG C of catalyst layer temperature, in maximum
When also stop at 52.2%, may not proceed sufficiently decomposition reaction.
In non-patent literature 5, using the ZSM5 added with Mo and Ce as catalyst, implement stone under vapor adding conditional
Cerebrol contact is decomposed.However, conversion ratio, also stops at 55.3% in maximum, may not proceed sufficiently decomposition reaction.In addition,
Reaction time be as short as 5 it is small when, do not carry out the continuous operation from the actuality from the aspect of practicality.
In the embodiment 11 of patent document 4, as catalyst layer, Pt catalyst is divided into leading portion, will be carried with Pr's
ZSM5 catalyst is divided into back segment, implements normal butane contact decomposition reaction under vapor adding conditional.However, the reaction can be predicted
In system, Pt catalyst is difficult to efficiently remove the coke and precursors of coke accumulated on ZSM5.
In the same manner as vapor, to carbonic acid gas it is also known that it is with coking inhibition.It is believed that by same with vapor
The mechanism of sample, promotes the removal of coke and precursors of coke using dry type reforming reaction, suppresses coking.In addition, to carbonic acid gas,
Know in addition to dry type reforming reaction, also promote oxidative dehydrogenation.
As the technique for adding carbonic acid gas as oxidizing gas and into saturation hydrocarbon feed, it can enumerate and for example utilize first
The benzene manufacture of the aromatic seriesization reaction of the rudimentary saturated hydrocarbons such as alkane, ethane, propane, utilizes the rudimentary saturation such as ethane, propane, butane
The rudimentary unsaturated hydro carbons of the dehydrogenation reaction of hydro carbons manufactures, using styrene manufacture of ethylbenzene dehydrogenation reaction etc., de- using oxidation
The reaction process (non-patent literature 8) of hydrogen reaction.Wherein, on aromatic series manufacturing process, it has been disclosed that added with carbonic acid gas
Under the conditions of, suitably use the example (non-patent literature 9 and 10) containing metal zeolite catalyst.On the other hand, stone brain is being utilized
The contact decomposition reaction of the rudimentary saturated hydrocarbons such as oil is manufactured in the technique of rudimentary unsaturated hydro carbons, it is necessary to which to suppress excessive dehydrogenation anti-
The progress answered, but not yet disclose for the suppression and apply the example of carbonic acid gas addition.
In patent document 2, implement the contact of the rudimentary saturated hydrocarbons such as naphtha point as using the zeolite catalyst containing P
The form of technique is solved, carbonic acid gas can be used as content as diluent gas by describing.However, the prior art document
In, carbonic acid gas is recited as the gas only for the purpose of diluting raw material, and completely without the meaning used as oxidizing gas
Figure, also completely without the coking inhibition contemplated on a catalyst.In addition, in the look-ahead technique document Prior Art, also do not disclose and add
Add the embodiment of the contact decomposition reaction of carbonic acid gas, on the contact decomposition technique of the rudimentary saturated hydrocarbons such as naphtha, make us complete
It can not expect the effect that catalyst life caused by adding is improved by carbonic acid gas.
In the embodiment of patent document 4, disclose in normal butane contacts decomposition reaction, contain in product by raw material
Reaction result as the carbonic acid gas for aoxidizing and generating.However, carbonic acid gas contained in product brings catalyst life
Influence it is indefinite, from practicality and it is economical from the viewpoint of, also implement continuous operation not under reality condition.
In general, it is known that the oxidation reaction such as VOC decomposition reactions, purifying vehicle exhaust reaction in reforming reaction, exhaust gas
In, by using the high oxygen ion conduction body of the Lattice Oxygen supply capacity such as perofskite type oxide and cerium oxide as carrier,
Improve the activity (such as non-patent literature 11~17 etc.) of metallic catalyst.However, the contact of the rudimentary saturated hydrocarbons such as naphtha point
In solution reaction, not yet disclose and pay close attention to this series of prior art and be used to improve by the Lattice Oxygen supply capacity of catalyst carrier
The example of catalyst life.
In conclusion if the contact decomposition reaction of the rudimentary saturated hydrocarbons such as naphtha is considered, hardly to passing through
Oxidizing gas is added in the feed to be studied come the technology for the coking for suppressing to trigger catalyst life to shorten, and can not also say it
Practical level is reached.In view of such circumstances, to the contact decomposition reaction of the rudimentary saturated hydrocarbons such as naphtha, expect a kind of
Suppress the generation of coke by oxidizing gas and efficiently long-term continuous production light alkene class can contain metal zeolite
Catalyst.
