Invention field

Invention relates to mesoporous catalyst, the mesopore molecular sieve of particularly new embedding zeolite, and it has high thermal stability, also relates to the method for preparing catalysis material.Said catalysis material is suitable for the hydrocarbon manufacture field.

Background technology

Mesopore molecular sieve has caused scientist's attention as catalysis material, because its particular performances, as having the very big uniform hole of high surface, its size is at 2-50nm.Yet mesopore molecular sieve well known in the prior art is normally warm and hydro-thermal is unsettled, and hole wall is unbodied and they have faintly acid.And in the regenerative process of spent catalyst, the mesopore molecular sieve structure possibly caved in after hydrocarbon processing.

Have the carrier of the crystalline material industrialization in pore size (d < 2nm) hole as catalyst and catalyst.Zeolite is the well-known instance of this material.Because its special performances, like the possibility of high surface area, high-adsorption-capacity and adjustment adsorption capacity, zeolite is able to extensive use.In zeolite structured, possibly produce the activated centre, set up the activated centre and the adjustment acid sites intensity and quantity.The aperture of zeolite heat endurance and the chemical stability at 0.4-1.2nm and zeolite usually is high.Yet the zeolite treatment molecule is limited greater than the ability of the molecule of zeolite pore, and zeolite inactivation in several reactions is quite fast.

US5,198,203 disclose and developed in the early 1990s be called M41S one group of neat mesopore molecular sieve.M41S has C _iH _2i(CH ₃) N ⁺-cation (i>7) one group of meso-porous molecular sieve material that the silica and the aqueous solution of alumina precursor form under hydrothermal condition.In this group the most famous member be hexagon MCM-41, cube MCM-48 and the MCM-50 of disc structure.The aperture of mesopore molecular sieve can be adjusted between 2-10nm and form and can comprise pure silica or metal silicon/silicon dioxide (like the substituted silica of Al-, V-and Ti-).The meso-porous molecular sieve material of M41S group is that unbodied hole system with them is neat natively.

US5 discloses the synthetic composition of the crystal phase that comprises super big hole in 246,689 and US5,334,368.Material is that the diameter in inorganic, porous, unstratified, hole is at 1.3-20mm.Pore-size distribution in single-phase scope is regular in a way.At least one peak of d-spacing is greater than 1.8nm in the X-ray diffracting spectrum.

EP0748652 discloses one group of mesoporous material (MSA) with narrow pore-size distribution.Material is unbodied and complete unordered.The BET surface area of material is 672-837m ²/ g.

The mesoporous material of synthetic preparation is nonacid or its acidity is limited.Through in the silicon dioxide structure of mesoporous material, mixing aluminium the quantity of the acid sites of mesoporous material is increased.Yet the acid intensity of aforesaid mesoporous material is less than the acid intensity of zeolite.

The whole bag of tricks of preparation mesoporous material is known in the prior art.Heat endurance, hydrothermal stability and the acidity of mesopore molecular sieve have been attempted increasing, as in meso-hole structure, introducing catalytic active species.Substantially, synthetic method comprises with one or more organic reagents and prepares silicon source solution that the PH of regulator solution then reclaims and the calcining deposition to deposition occurring.The aluminium source adds in the solution under the temperature that arbitrary steps before the synthetic beginning has improved.Several kinds of surfactants and template (organic reagent), component, solvent and reaction condition have been proposed.

US5, a kind of method for preparing mesoporous material of 942,208 records, this mesoporous material has improved hydrothermal stability with respect to MCM-41.Various salt in the method, have been used and with the PH of weak acid regulator solution.

EP0795517 has proposed a kind of method of synthesize meso-porous material, wherein uses silicon source and the mixture that comprises the organic formwork of fluorine.

US5,942,208 have described the preparation of mesopore molecular sieve, and this mesopore molecular sieve has heat endurance and the hydrothermal stability that is higher than traditional mesopore molecular sieve.Material boiled in water 12 hours and structure not variation basically.

The stable method with mesoporous material activity of selectable preparation is that zeolite is incorporated in the mesoporous wall.US09/764,686 disclose the synthetic of the mesoporous material that uses Y-zeolite seed crystal, MFI zeolite seed crystal and beta-zeolite crystal seed.

CN1349929 proposes to use L-zeolite precursor formulations prepared from solutions MSA-3 and MAS-8.

Kloetstra et al, Micropor.Mesopor.Mater.6 (1996) 287 have reported that original position forms faujasite and MCM-41.Their method is based on the sequence of zeolite and MCM-41 and synthesizes.

Karlsson et al .Micropor.Mesopor.Mater.27 (1999) 181 disclose method while synthetic zeolite/MCM-41 phase of using hybrid template.

Be at growth on the zeolite and deposition MCM-41 or in gel, add under the situation of zeolite seed crystal that in synthetic method material can be two phase or heterogeneous mixture, the perhaps zeolite of loose bonding and mesoporous materials.

Two kinds of dissimilar templates in synthesize meso-porous material, have been used.This preparation method's reproducibility is difficult to.And, there is not chemical reaction between zeolite and the mesopore molecular sieve, the heat endurance of the material that obtains and hydrothermal stability possibly be low.

According to the situation of prior art, mesopore molecular sieve is widely used in the catalyst as mutually active or carrier.Several kinds of hydrocarbon conversion reactions are acid catalyzed.Based on their acid catalysis effect, known zeolites has activity in processes such as the open loop of the oligomerisation of the dimerization of two keys of alkene and skeletal isomerizationization, paraffin isomerization, cracking, alkene, alkene, cycloalkanes, alkylation, the exchange of aromatic alkyl, aromatic radicalization.Bifunctional catalyst with metal or metal oxide or sulfide phase is applied in the reaction, like isomerization, hydrocrack, catalytic dewaxing, dehydrogenation sulfuration, dehydrogenation oxidation, dehydrogenation nitrogenize and several kinds of hydrogenations of reformation, paraffin.The major defect that uses zeolite is that their deactivation are higher macromolecular limited in one's ability with processing.

Can find based on foregoing need be based on the method for a kind of so thermally-stabilised and hydrothermally stable catalysis material of the catalysis material of the thermally-stabilised and hydrothermally stable of mesopore molecular sieve and preparation.And obviously needing a kind of catalyst, it has the zeolite type active site and reactant is short to the evolving path of accessibility height, reactant and the product of active site, with restriction side reaction and coking.

* interparticle pore size

Zeolite is differentiated through X-ray diffraction (XRD).When the suitable interior timestamp of use can characterize and MCM-41 unit cell dimension mutually from XRD figure.Use α-Al ₂O ₃Or TiO ₂(rutile) is as interior mark.

The size of MFI structure cell characterizes through ASTM D3942-97 method, uses α-Al ₂O ₃As interior mark.

The structure cell of MWW is confirmed through improved ASTM D 3942-97 method, uses α-Al ₂O ₃As interior mark and be positioned at 7.2 ° of 2 θ [100] reflection.

The unit cell dimension of MMMO is not through there being the location estimation at peak under the interior mark condition.The estimation formula is $a_0=2*d_{\left[100\right]}/\sqrt{3}.$

The unit cell dimension of mesopore molecular sieve (MCM-41) is through J.S.Beckeretal., and the method for record is estimated among the J.Am.Chem.Soc.114 (1992) 10834.

The size of zeolite structure cell is corresponding to the quantity of the Al that mixes in zeolite structured.The Al atom is greater than the Si atom, and therefore unit cell dimension increases along with the increase of Al quantity usually in most of zeolites.On the contrary, by table 2 (MFI, BEA, MWW and MOR a ₀Can find that value) unit cell dimension reduces along with the increase of Al quantity in the MM5 catalysis material in the zeolite of embedding.The variation of MCM-41 unit cell dimension (VCD) is uncorrelated with the quantity of Al, and it weakens along with the increase of MFI phase intensity.The variation of unit cell dimension is the clear evidence that chemical bonding takes place between the zeolite of mesopore molecular sieve and embedding really.

In order to increase uniformity and the dispersiveness of zeolite nuclear in gel solution, it is important carrying out strong stirring after the adding zeolite nuclear in the gel preparation course.

The catalysis material that obtains randomly converts corresponding proton form to through ammonium ion exchange and calcining.The suitable raw material that is used for ammonium ion exchange is ammonium salt such as ammonium nitrate or ammonium chloride.Catalysis material is handled under as 1 to 6 hour with suitable time interval at 25-80 ℃ in the aqueous solution of ammonium salt.The alkaline earth of ammonium cation alternate material or base cations in processing procedure.Can adjust the ion-exchange degree through the time that changes processing, the concentration and the temperature of ammonium salt solution.After ion-exchange treatment, the dry material that obtains with calcining is proton and ammonia to decompose ammonium ion.

According to catalysis material of the present invention, the mesopore molecular sieve of novel embedding zeolite can comprise the method that deposition, deposition, sealing and selectivity remove and carries out modification through being selected from.Dipping and ion-exchange are deposition process.In dipping, deposit from liquid phase, and absorption, ion-exchange and selective reaction take place on carrier or carry out with carrier surface.In removing the liquid process, the crystal of non-individual layer forms on the surface.In ion-exchange, use the solution of dilution, the metal ion of expectation exchanges to the cation or the proton of material substitution solid material from solution.Goal response is depended in the method and the selection of modification.Preferred ion switching method during usually, when the low load that needs metal with than high dispersive.

It is necessary after synthetic the completion, removing surfactant, with the mesopore molecular sieve of the embedding zeolite that obtains having high surface and high acidity.Calcining heat, the rate of heat addition and duration influence surface area, pore-size distribution and the aluminium position in structure.The bigger serface (by nitrogen adsorption assay) of the mesopore molecular sieve of synthetic novel embedding zeolite has confirmed that with different strong acidity (TPD by ammonia measures) substep calcination program is the very proper method of removing surfactant.

From the mesopore molecular sieve of embedding zeolite, removing template also is to carry out in substep calcination program.

The synthetic of mesoporous material can carry out under the condition that is with or without extra aluminium source.In catalysis material is synthetic, only need a kind of template.

Catalysis material can be sneaked into carrier or loads on the carrier through the known method of prior art.

Synthetic method is introduced the zeolite properties of expectation thus through bonding zeolitic material in mesoporous material and is kept the complete crystal degree of hole wall that causes of meso-hole structure to increase simultaneously.In the method, be used for the only template of one type of needs of the synthetic gel solution of product.

At the small crystals of the synthetic mesolite of mesoporous material as " nuclear " and can change the concentration of " nuclear " and the size of zeolite catalyst.This causes the zeolite nuclear concentration to increase and causes a large amount of microcellular structures of embedding and the mesoporous wall degree of crystallinity of increase in the mesopore molecular sieve.It also influences heat endurance and the hydrothermal stability and the acidity of material.The variation of zeolite nuclear size possibly influence the shape alternative of material.

The high thermal stability and the hydrothermal stability of the mesopore molecular sieve of embedding zeolite such as MFI, BEA, MWW and MOR structure among x-ray diffraction pattern, ESEM and nitrogen adsorption characterization result confirmation the present invention.

And, at different hydrocarbon conversion reactions, as just-butane and 1-isomerization of butene and the oligomerisation of 1-decene in used catalyst can be fully or almost completely regeneration, and the stability of catalysis material has also been explained in the maintenance of catalytic activity.

The preparation method makes the characteristic acidity in the design mesopore molecular sieve become possibility.The characteristic acidity of meso-porous molecular sieve material can use aluminium source and Si/Al ratio that changes gel solution and change different zeolites nuclear to design.The characterization result of the ammonia TPD of H-MM5, H-MMBE and H-MMMW catalyst and different test reactions as just-the butane isomerization confirms to show aspect these materials of different acidity it is being successful in design.

The hole wall of mesoporous material is unbodied in MCM-41, but their show the degree of crystallinity that increases along with the adding of zeolite.Product mesolite structure cell of the present invention is different from the structure cell in zeolite and the mesopore molecular sieve mechanical impurity, and the structure cell of mesopore molecular sieve is greater than its structure cell in mechanical impurity.

Other principal character of product is that most of zeolite facies are chemically bound in mesopore molecular sieve.Product is heat-staple under at least 900 ℃ of temperature in air.

The method of the mesopore molecular sieve of the embedding zeolite of invention and this material of preparation obviously is different from the disclosed product of prior art and method and has shown several advantages.

Shown in XRD and SEM figure and surface area measurement, the new MM5 mesopore molecular sieve of embedding MFT structure is heat-staple until at least 1000 ℃, and MMBE is at least 900 ℃.

Through with the ion-exchange of aqueous ammonium nitrate solution; Then change at the cation of 100 ℃ of dryings and the MM5 that carries out 500 ℃ of calcinings, MMBE, MMMW and MMMO; Like the Na-type among the embodiment, convert the proton type of corresponding M M5, MMBE, MMMW and MMMO to, shown in XRD figure; Do not change structure, the hydrothermal stability of new material has been described.Known MCM-41 structure at high temperature with after water contacts is caved in.

Carry out metal-modified to MM5, MMBE, MMMW and MMMO; (use the aqueous solution of chloroplatinic acid to carry out 24 hours like particularly platinum modification of noble metal among the embodiment at 80 ℃; Then 100 ℃ of dryings with 450 ℃ of calcinings), XRD figure shows the structure that can't influence MM5 and MMBE.This illustrative material is stable in acid medium.

The proton type of the mesopore molecular sieve of embedding MFI structure just-show very high activity in the reaction of butane and 1-isomerization of butene.The H-MM5 catalyst just showing-butanes conversion increases with acidity.

The proton type of the mesopore molecular sieve of embedding MFI and BEA structure shows very high activity in the 1-dimerizing olefins.H-MM5 and H-MMBE catalyst show that 1-decene conversion ratio increases and increases along with acidity.The proton type of the mesopore molecular sieve of embedding MFI structure shows very high activity and catalyst non-inactivation in the isobutene dimerization.

H-MM5 and the holomorphosis in air of H-MMBE catalysis material.The material of regeneration shows in normal butane and 1-isomerization of butene and the oligomerisation of 1-decene and raw catelyst catalytic activity much at one.One of subject matter of known MCM-41 catalyst is regeneration, and promptly meso-hole structure caves in after the regeneration.The catalytic activity of the new mesopore molecular sieve of embedding zeolitic material keeps explanation clearly to regenerate afterwards in two reactions, and structure is stable.

Pt-MM5 just-show that very high conversion and catalysis material keep its catalytic activity after regeneration in the butane isomerization.

Pt-MMBE demonstrates the high selectivity of divided ring product.

Therefore needn't use modification after synthetic with enhancing heat endurance and hydrothermal stability for MM5 and MMBE mesoporous material.The high thermal stability of new material and hydrothermal stability are embedded in the mesopore molecular sieve wall owing to using said method with zeolite like MFI and BEA structure.

The new mesoporous material of this group need not to be used for cracking, the aromatic alkylation of isomerization, the hydrocarbon of oligomerisation, the alkene of dimerization, the alkene of alkene, aromatization, etherificate, dehydration and the ring-opening reaction of light hydrocarbon through the further modification of active material just being can be used as catalyst.Metal-modified material shows high activity in the isomerization of lightweight paraffin.Likewise; When using the manner known in the art modification, metal-modified material also is activated in isomerization, hydrogenation, hydrogen cracking, hydrodesulfurization, hydrogenation deoxidation, hydrodenitrogeneration, dehydrogenation, reformation, Fischer-Tropsch reaction and the oxidation reaction of long-chain paraffin.Metal in the catalyst can be form metallic state, oxide or sulfide or with any other form of prior art known way modification.

The material of invention also can as adsorb in different separation techniques, absorb or selectivity is removed middle use.

Below exemplary embodiment invention and actual embodiment thereof are described better, yet obviously to those skilled in the art scope of invention never be limited to these embodiment.
