METHOD OF PREPARATION AND USE

STATEMENT OF PRIORITY

[0001] This application claims priority to U.S. Application No. 13/689,887 which was filed November 30, 2012, and U.S. Application No. 13/689,893 which was filed on

November 30, 2012, now US 8,569,557, the contents of which are hereby incorporated by reference in its entirety.

FIELD OF THE INVENTION

[0002] This invention relates to a new family of charged microporous

silicometallosphosphate molecular sieves designated MAPSO-64. They are represented by the empirical formula of:

R⁺ _rM_m ⁿ⁺EP_xSi_yO_z where M is a divalent metal such as magnesium or zinc, R is an organoammonium cation such as diethyldimethylammonium or ethyltrimethylammonium and E is a trivalent element such as aluminum or gallium.

BACKGROUND OF THE INVENTION

[0003] Zeolites are crystalline aluminosilicate compositions which are microporous and which are formed from corner sharing A10₂ ^~ and Si0₂ tetrahedra. Numerous zeolites, both naturally occurring and synthetically prepared are used in various industrial processes. Synthetic zeolites are prepared via hydrothermal synthesis employing suitable sources of Si, Al and structure directing agents such as alkali metals, alkaline earth metals, amines, or organoammonium cations. The structure directing agents reside in the pores of the zeolite and are largely responsible for the particular structure that is ultimately formed. These species balance the framework charge associated with aluminum and can also serve as space fillers. Zeolites are characterized by having pore openings of uniform dimensions, having a significant ion exchange capacity, and being capable of reversibly desorbing an adsorbed phase which is dispersed throughout the internal voids of the crystal without significantly displacing any atoms which make up the permanent zeolite crystal structure. Zeolites can be used as catalysts for hydrocarbon conversion reactions, which can take place on the outside surfaces of the zeolite as well as on internal surfaces within the pores of the zeolite.

[0004] It is possible to use essentially the same techniques to produce microporous materials of other compositions, e.g., non-zeolitic compositions. In 1982, Wilson et al. first reported aluminophosphate molecular sieves, typically called AlPOs, which are microporous materials that have many of these same properties of zeolites, although they are silica free, composed of A10₂ ^" and P0₂ ⁺ tetrahedral, see US 4,310,440. Subsequently, charge was introduced to the neutral aluminophosphate frameworks via the substitution of Si0₂ tetrahedra for P0₂ ⁺ tetrahedra to produce the typically called SAPO molecular sieves, see US 4440871. Another way to introduce framework charge to neutral aluminophosphates is to substitute [M²⁺0₂]^2~ tetrahedra for A10₂ ^" tetrahedra, which yield the MeAPO molecular sieves, see US 4567029. It is furthermore possible to introduce framework charge on A1PO- based molecular sieves via the simultaneous introduction of Si0₂ and [M²⁺0₂]^2~ tetrahedra to the framework, giving MeAPSO molecular sieves as shown in US 4973785.

[0005] Applicants have synthesized a new family of charged microporous

silicometallophosphate framework materials with MeAPSO compositions designated

MAPSO-64. The MAPSO-64 materials have the BPH topology, which contains a 12-ring pore system with a perpendicular 8-ring pore system, see for example http://izasc- mirror.la.asu.edu/fmi/xsl/IZA-SC/ftc_fw.xsl?-db=Atlas_main&-lay=fw&- max=25&STC=BPH&-find. With respect to AlPO-based materials, the BPH topology has previously been prepared in a MAPO composition of the material known as STA-5, which uses the complicated triquat template 1, 3, 5-Tris (triethylammoniomethyl) benzene, see Patinec et. al. in Chem. Mater., 11, 2456-2462 (1999). By contrast, the microporous MAPSO- 64 materials of the present invention additionally includes Si in the framework and can be prepared with the much simpler structure directing agents diethyldimethylammonium

(DEDMA⁺) or ethyltrimethylammonium (ETMA⁺).

SUMMARY OF THE INVENTION

[0006] As stated, the present invention relates to a new family of microporous

silicometallophosphate molecular sieves designated MAPSO-64. One embodiment of the invention is a microporous crystalline material having a three-dimensional framework of containing E0₂ ^~ , P0₂ ⁺, [M²⁺0₂]^2~ and Si0₂ tetrahedral units and an empirical composition in the as synthesized and anhydrous basis expressed by an empirical formula of:

[0007] Another embodiment of the invention is a process for preparing the crystalline microporous aluminum phosphate-based molecular sieve described above. The process comprises forming a reaction mixture containing reactive sources of R, E, P, and either one or both of M and Si and heating the reaction mixture at a temperature of 60°C to 200°C for a time sufficient to form the molecular sieve, the reaction mixture having a composition expressed in terms of mole ratios of the oxides of: aR₂0 : bMO : E₂0₃ : cP₂0₅ : dSi0₂ : eH₂0 where "a" has a value of 0.75 to 16, "b" has a value of 0.01 to 3, "c" has a value of 0.8 to 8, "d" has a value of 0.01 to 4, and "e" has a value from 20 to 800.

[0008] Yet another embodiment of the invention is a hydrocarbon conversion process using the above-described molecular sieve as a catalyst. The process comprises contacting at least one hydrocarbon with the molecular sieve at conversion conditions to generate at least one converted hydrocarbon.

[0009] Still another embodiment of the invention is a separation process using the crystalline MAPSO-64 material. The process may involve separating mixtures of molecular species or removing contaminants by contacting a fluid with the MAPSO-64 molecular sieve. Separation of molecular species can be based either on the molecular size (kinetic diameter) or on the degree of polarity of the molecular species. Removing contaminants may be by ion exchange with the molecular sieve. DETAILED DESCRIPTION OF THE INVENTION

[0010] Applicants have prepared a family of microporous silicometallophosphate materials whose structures exhibit the BPH topology. The instant microporous crystalline material (MAPSO-64) has an empirical composition in the as-synthesized form and on an anhydrous basis expressed by the empirical formula:

Pv⁺ _rM_m ²⁺EP_xSi_yO_z where M is at least one divalent metal cation and is selected from the group consisting of alkaline earth and transition metals. Specific examples of the M cations include but are not limited to beryllium, magnesium, cobalt (II), manganese, zinc, iron(II), nickel and mixtures thereof. R is an organoammonium cation, examples of which include but are not limited to the choline cation, [(CH₃)3N(CH₂)₂0H]⁺, tetramethylammonium cation (TMA⁺),

ethyltrimethylammonium (ETMA⁺), trimethylpropylammonium, diethyldimethylammonium (DEDMA⁺), methyltriethylammonium (MTEA⁺), trimethylpropylammonium (PTMA⁺), dimethyldiethanolammonium, tetraethylammonium (TEA⁺), dimethyldipropylammonium (DPDMA⁺), tetrapropylammonium (TPA⁺) and mixtures thereof and "r" is the mole ratio of R to E and varies from 0.1 to 2.0. The value of "m" is the mole ratio of M to E and varies from 0.01 to 1.5, "x" is mole ratio of P to E and varies from 0.5 to 2.5. The ratio of silicon to E is represented by "y" which varies from O.Ol to l.O. E is a trivalent element which is tetrahedrally coordinated, is present in the framework and is selected from the group consisting of aluminum, gallium, iron(III) and boron. Lastly, "z" is the mole ratio of O to E and is given by the equation: z = (2 * m + r + 3 + 5 * x + 4 * y)/2.

[0011] The microporous crystalline silicometallophosphate material, MAPSO-64, is prepared by a hydrothermal crystallization of a reaction mixture prepared by combining reactive sources of R, E, phosphorous, M and silicon. When E is aluminum, the sources of include but are not limited to aluminum alkoxides, precipitated aluminas, aluminum metal, aluminum hydroxide, aluminum salts and alumina sols. Specific examples of aluminum alkoxides include, but are not limited to aluminum ortho sec-butoxide and aluminum ortho isopropoxide. Sources of other E elements include but are not limited to organoammonium borates, boric acid, precipitated gallium oxyhydroxide, gallium sulfate, ferric sulfate, and ferric chloride. Sources of phosphorus include, but are not limited to, orthophosphoric acid, phosphorus pentoxide, and ammonium dihydrogen phosphate. Sources of silica include but are not limited to tetraethylorthosilicate, colloidal silica, and precipitated silica. Sources of the M metals include the halide salts, nitrate salts, acetate salts, and sulfate salts of the respective alkaline earth and transition metals. R is an organoammonium cation selected from the group consisting of choline, TMA⁺, ETMA⁺, DEDMA⁺, MTEA⁺, TEA⁺, TPA⁺, PTMA⁺, DPDMA⁺, dimethyldiethanolammonium and mixtures thereof, and the sources include the hydroxide, chloride, bromide, iodide and fluoride compounds. Specific examples include without limitation choline hydroxide and choline chloride, ethyltrimethylammonium hydroxide, diethyldimethylammonium hydroxide, diethyldimethylammonium chloride, methyltriethylammonium hydroxide, and methyltriethylammonium chloride. In a specific embodiment, R is DEDMA⁺. In another embodiment, R is at ETMA⁺. In another

embodiment, R is a combination of DEDMA⁺ and at least one singly charged

organoammonium cation selected from the group consisting of choline, TMA⁺, ETMA⁺, MTEA⁺, PTMA⁺, dimethyldiethanolammonium, TEA⁺, DPDMA⁺ and TPA⁺. In yet another embodiment, R is a combination of ETMA⁺ and at least one singly charged

organoammonium cation selected from the group consisting of choline, TMA⁺, DEDMA⁺, MTEA⁺, PTMA⁺, DPDMA⁺, dimethyldiethanolammonium, TEA⁺, and TPA⁺.

[0012] The reaction mixture containing reactive sources of the desired components can be described in terms of molar ratios of the oxides by the formula: aR₂0 : bMO : E₂0₃ : cP₂0₅ : dSi0₂ : elsewhere "a" varies from 0.75 to 16, "b" varies from 0.01 to 3, "c" varies from 0.8 to 8, "d" varies from 0.01 to 4, and "e" varies from 20 to 800. If alkoxides are used, a distillation or evaporative step may be included to remove the alcohol hydrolysis products. The reaction mixture is now reacted at a temperature of 60°C to 200°C, or in another embodiment, from 115°C to 175°C for a period of 1 day to 3 weeks or in another embodiment, 1 day to 7 days in a sealed reaction vessel under autogenous pressure. After crystallization is complete, the solid product is isolated from the heterogeneous mixture by means such as filtration or centrifugation, and then washed with deionized water and dried in air at ambient temperature up to 100°C. MAPSO-64 seeds can optionally be added to the reaction mixture in order to accelerate the formation of the desired microporous composition. [0013] The MAPSO-64 silicometallophosphate-based material, which is obtained from the above-described process, is characterized by the x-ray diffraction pattern, having at least the d- spacings and relative intensities set forth in Table A below.

Table A

[0014] The MAPSO-64 may be modified in many ways to tailor it for use in a particular application. Modifications include calcination, ammonia calcinations, ion-exchange, steaming, various acid extractions, ammonium hexafluorosilicate treatment, or any combination thereof, as outlined for the case of UZM-4 in US 6,776,975 Bl which is incorporated by reference in its entirety. Properties that may be modified include porosity, adsorption, framework composition, acidity, thermal stability, etc. [0015] As synthesized, the MAPSO-64 material will contain some of the exchangeable or charge balancing cations in its pores. These exchangeable cations can be exchanged for other cations, or in the case of organic cations, they can be removed by heating under controlled conditions. With the large 12-ring pore BPH topology of MAPSO-64, small organoammonium cations can often be removed directly by ion-exchange. In one embodiment, the method of removing organic cations from the pores is ammonia calcination. Calcination in air converts organic cations in the pores to protons, which can, for example, lead to some removal of Al from the framework upon exposure to water vapor. When the calcination is carried out in an ammonia atmosphere, the organic cation in the pore is replaced by NH₄ ⁺ cation and the framework remains intact, see Studies in Surface Science, (2004) vol. 154, p.1324 - 1331. Typical conditions for ammonia calcinations include the use of gaseous anhydrous ammonia flowing at a rate of 1.1 1/min while ramping the sample at 2 - 5°C/min to 500°C and holding at that temperature for a time ranging from 5 minutes to 4 hours. The resulting ammonium form of MAPSO-64 has essentially the diffraction pattern of Table A. The ammonium form of MAPSO- 64 may then be ion-exchanged to any other form, resulting in a material with a modified composition, MAPSO-64M, given by the empirical formula:

M'_n ^p+M_m ²⁺EP_xSi_yO_z where M is at least one divalent metal cation selected from the group consisting of Be²⁺, Mg²⁺, Zn²⁺, Co²⁺, Mn²⁺, Fe²⁺ , Ni²⁺, "m" is the mole ratio of M to E and varies from 0.01 to 1.5, M' is NH₄ ⁺, H⁺, alkali metals, alkaline earth metals, transition metals and rare earth metals and mixtures thereof, "n" is the mole ratio of M' to E and has a value of 0.03 to 2.0, "p" is the weighted average valence of M', E is a trivalent element selected from the group consisting of aluminum, gallium, iron, boron and mixtures thereof, "x" is mole ratio of P to E and varies from 0.5 to 2.0, "y" is the mole ratio of Si to E and varies from 0.01 to 1.0 and "z" is the mole ratio of O to E and has a value determined by the equation: ζ = (ρ · η + 2 · ιη + 3 + 5 · χ + 4 · y)/2 and is characterized in that it has the x-ray diffraction pattern having at least the d-spacings and intensities set forth in Table A:

[0016] In one embodiment of the invention, the MAPSO-64 is thermally stable up to a temperature of at least 400°C, and in another embodiment the MAPSO-64 is thermally stable up to a temperature of at least 500°C.

[0017] When MAPSO-64 is calcined in air and ambient water vapor, there can be loss of metal from the framework, such as Al, which can alter the x-ray diffraction pattern from that observed for the as-synthesized MAPSO-64 in Table A, see Studies in Surface Science, (2004) vol.154, p.1324 - 1331. The air-calcined MAPSO-64 materials, MAPSO-64C, are characterized by the empirical formula:

H_aM_m ²⁺EP_xSi_yO_z where M is at least one divalent metal cation selected from the group consisting of Be²⁺,

Mg²⁺, Zn²⁺, Co²⁺, Mn²⁺, Fe²⁺ , Ni²⁺, "m" is the mole ratio of M to E and varies from 0.01 to

1.5, H is a proton, "a" is the mole ratio of H to E and has a value of 0.1 to 2.0, E is a trivalent element selected from the group consisting of aluminum, gallium, iron, boron and mixtures thereof, "x" is mole ratio of P to E and varies from 0.5 to 2.5, "y" is the mole ratio of Si to E and varies from 0.01 to 1.0 and "z" is the mole ratio of O to E and has a value determined by the equation: z = (a + 2 * m + 3 + 5 * x + 4 * y)/2 [0018] The crystalline MAPSO-64 material of this invention can be used for separating mixtures of molecular species, removing contaminants through ion exchange and catalyzing various hydrocarbon conversion processes. Separation of molecular species can be based either on the molecular size (kinetic diameter) or on the degree of polarity of the molecular species.

[0019] The MAPSO-64 compositions of this invention can also be used as a catalyst or catalyst support in various hydrocarbon conversion processes. Hydrocarbon conversion processes are well known in the art and include cracking, hydrocracking, alkylation of both aromatics and isoparaffin, isomerization, polymerization, reforming, hydrogenation, dehydrogenation, transalkylation, dealkylation, hydration, dehydration, hydrotreating, hydrodenitrogenation, hydrodesulfurization, methanol to olefins, methanation and syngas shift process. Specific reaction conditions and the types of feeds which can be used in these processes are set forth in US 4,310,440, US 4,440,871 and US 5,126,308, which are hereby incorporated by reference. Preferred hydrocarbon conversion processes are those in which hydrogen is a component such as hydrotreating or hydrofining, hydrogenation, hydrocracking, hydrodenitrogenation, hydrodesulfurization, etc.

[0020] Hydrocracking conditions typically include a temperature in the range of 400° to

1200°F (204-649°C), preferably between 600° and 950°F (316-510°C). Reaction pressures are in the range of atmospheric to 3,500 psig (24,132 kPa g), preferably between 200 and 3000 psig (1379 - 20,685 kPa g). Contact times usually correspond to liquid hourly space velocities (LHSV) in the range of 0.1 hr^-1 to 15 hr^-1, preferably between 0.2 and 3 hr ¹. Hydrogen circulation rates are in the range of 1 ,000 to 50,000 standard cubic feet (scf) per barrel of charge (178-8,888 std. m³/m³), preferably between 2,000 and 30,000 scf per barrel of charge (355-5,333 std. m³/m³). Suitable hydrotreating conditions are generally within the broad ranges of hydrocracking conditions set out above.

[0021] The reaction zone effluent is normally removed from the catalyst bed, subjected to partial condensation and vapor-liquid separation and then fractionated to recover the various components thereof. The hydrogen, and if desired some or all of the unconverted heavier materials, are recycled to the reactor. Alternatively, a two-stage flow may be employed with the unconverted material being passed into a second reactor. Catalysts of the subject invention may be used in just one stage of such a process or may be used in both reactor stages.

[0022] Catalytic cracking processes are preferably carried out with the MAPSO-64 composition using feedstocks such as gas oils, heavy naphthas, deasphalted crude oil residua, etc. with gasoline being the principal desired product. Temperature conditions of 850° to 1100°F, LHSV values of 0.5 to 10 and pressure conditions of from 0 to 50 psig are suitable.

[0023] Alkylation of aromatics usually involves reacting an aromatic (C₂ to C₁₂), especially benzene, with a monoolefin to produce a linear alkyl substituted aromatic. The process is carried out at an aromatic: olefin (e.g., benzene: olefin) ratio of between 5 : 1 and 30: 1 , a LHSV of 0.3 to 6 hr^"1, a temperature of 100° to 250°C and pressures of 200 to 1000 psig. Further details on apparatus may be found in US 4,870,222 which is incorporated by reference.

[0024] Alkylation of isoparaffins with olefins to produce alkylates suitable as motor fuel components is carried out at temperatures of -30° to 40°C, pressures from atmospheric to 6,894 kPa (1 ,000 psig) and a weight hourly space velocity (WHSV) of 0.1 to 120. Details on paraffin alkylation may be found in US 5,157,196 and US 5,157,197, which are incorporated by reference.

[0025] The conversion of methanol to olefins is effected by contacting the methanol with the MAPSO-64 catalyst at conversion conditions, thereby forming the desired olefins. The methanol can be in the liquid or vapor phase with the vapor phase being preferred. Contacting the methanol with the MAPSO-64 catalyst can be done in a continuous mode or a batch mode with a continuous mode being preferred. The amount of time that the methanol is in contact with the MAPSO-64 catalyst must be sufficient to convert the methanol to the desired light olefin products. When the process is carried out in a batch process, the contact time varies from 0.001 hrs to 1 hr and preferably from 0.01 hr to 1. 0 hr. The longer contact times are used at lower temperatures while shorter times are used at higher temperatures. Further, when the process is carried out in a continuous mode, the Weight Hourly Space Velocity (WHSV) based on methanol can vary from 1 hr^"1 to 1000 hr^"1 and preferably from lhr^"1 to 100 hr^"1.

[0026] Generally, the process must be carried out at elevated temperatures in order to form light olefins at a fast enough rate. Thus, the process should be carried out at a temperature of 300 °C to 600 °C, preferably from 400 °C to 550 °C and most preferably from 450 °C to 525 °C. The process may be carried out over a wide range of pressure including autogenous pressure. Thus, the pressure can vary from 0 kPa (0 psig) to 1724 kPa (250 psig) and preferably from 34 kPa (5 psig) to 345 kPa (50 psig).

[0027] Optionally, the methanol feedstock may be diluted with an inert diluent in order to more efficiently convert the methanol to olefins. Examples of the diluents which may be used are helium, argon, nitrogen, carbon monoxide, carbon dioxide, hydrogen, steam, paraffmic hydrocarbons, e. g., methane, aromatic hydrocarbons, e. g., benzene, toluene and mixtures thereof. The amount of diluent used can vary considerably and is usually from 5 to 90 mole percent of the feedstock and preferably from 25 to 75 mole percent.

[0028] The actual configuration of the reaction zone may be any known catalyst reaction apparatus known in the art. Thus, a single reaction zone or a number of zones arranged in series or parallel may be used. In such reaction zones the methanol feedstock is flowed through a bed containing the MAPSO-64 catalyst. When multiple reaction zones are used, one or more MAPSO-64 catalysts may be used in series to produce the desired product mixture. Instead of a fixed bed, a dynamic bed system, e. g., fluidized or moving, may be used. Such a dynamic system would facilitate any regeneration of the MAPSO-64 catalyst that may be required. If regeneration is required, the MAPSO-64 catalyst can be continuously introduced as a moving bed to a regeneration zone where it can be regenerated by means such as oxidation in an oxygen containing atmosphere to remove carbonaceous materials.

[0029] The following examples are presented in illustration of this invention and are not intended as undue limitations on the generally broad scope of the invention as set out in the appended claims. The products will be designated as MeAPSO-64 to reflect the composition and structure.

[0030] The structure of the MAPSO-64 compositions of this invention was determined by the analysis of x-ray powder patterns. The x-ray patterns presented in the following examples were obtained using standard x-ray powder diffraction techniques. The radiation source was a high-intensity, x-ray tube operated at 45 kV and 35 mA. The diffraction pattern from the copper K-alpha radiation was obtained by appropriate computer based techniques. Flat compressed powder samples were continuously scanned at 2° to 56° (2Θ). Interplanar spacings (d) in Angstrom units were obtained from the position of the diffraction peaks expressed as Θ where Θ is the Bragg angle as observed from digitized data. Intensities were determined from the integrated area of diffraction peaks after subtracting background, "I₀" being the intensity of the strongest line or peak, and "I" being the intensity of each of the other peaks. [0031] As will be understood by those skilled in the art the determination of the parameter 2Θ is subject to both human and mechanical error, which in combination can impose an uncertainty of ±0.4° on each reported value of 2Θ. This uncertainty is, of course, also manifested in the reported values of the d-spacings, which are calculated from the 2Θ values. This imprecision is general throughout the art and is not sufficient to preclude the differentiation of the present crystalline materials from each other and from the compositions of the prior art. In some of the x-ray patterns reported, the relative intensities of the d-spacings are indicated by the notations vs, s, m, and w which represent very strong, strong, medium, and weak, respectively. In terms of 100 x I/I₀, the above designations are defined as: w = 0-15; m = 15-60: s = 60-80 and vs = 80-100

[0032] In certain instances the purity of a synthesized product may be assessed with reference to its x-ray powder diffraction pattern. Thus, for example, if a sample is stated to be pure, it is intended only that the x-ray pattern of the sample is free of lines attributable to crystalline impurities, not that there are no amorphous materials present.

[0033] In order to more fully illustrate the invention, the following examples are set forth. It is to be understood that the examples are only by way of illustration and are not intended as an undue limitation on the broad scope of the invention as set forth in the appended claims.

EXAMPLE 1

[0034] A Teflon beaker was charged 1 OO.OOg DEDMAOH (20 %), which was then stirred with a high-speed mixer. Then 4.65 g Al(OH)₃ (78.1%) was added a bit at a time with stirring until the reaction mixture was nearly a clear solution. Next 5.94 g TEOS (98%) was added quickly via dropper. The reaction mixture was stirred for 1.5 hours to give the TEOS a chance to hydrolyze. The reaction mixture was then treated with 12.89 g H₃P0₄ (85 %), added dropwise over a 15 minute period and allowed to stir for an additional 20 minutes, at which point the solution was clear. Separately, 20.5 g Zn(OAc)₂*2H₂0 was dissolved in lO.OOg de-ionized water. This solution was added slowly, dropwise, and the reaction mixture remained a clear solution. The reaction mixture was stirred for an additional hour before it was distributed among 7 Teflon-lined autoclaves, and digested at autogenous pressures at various temperatures and time periods. The products were isolated and washed with de- ionized water by centrifugation. The products resulting from reaction mixtures digested at 150°C for 55 and 152 hours and 175°C for 55 hours were identified as ZAPSO-64 by powder x-ray diffraction. Table 1 below shows representative diffraction lines for the 150°C/152 hour phase.
