摘要:
A family of microporous aluminosilicate zeolites and substituted versions thereof which are identified as UZM-8 and UZM-8HS have been prepared. These UZM-8 compositions can be prepared using either only one or more organoammonium cations, such as diethyldimethylammonium or ethyltrimethylammonium cations and optionally an alkali and/or an alkaline earth cation as structure directing agents. The UZM-8 compositions are described by an empirical formula of M m n+ R r p+ Al 1-x E x Si y O z and have a unique x-ray diffraction pattern. The UZM-8HS are derived from the UZM-8 zeolites and have a lower aluminum content than the UZM-8 compositions. These UZM-8HS are represented by the empirical formula M’ m’ n+ R r’ p+ Al (1-x) E x Si y’ O z’ and are prepared by treatments such as acid extraction and AFS treatments. Both the UZM-8 and UZM-8HS are useful in various hydrocarbon conversion processes.

摘要:
The present invention relates to a microporous crystalline material of zeolithic nature and called ITQ-10, to the process for the preparation of such material and to the use of ITQ-10 in processes for separating and transforming organic compounds. In calcined and anhydrous state, the chemical composition of the ITQ-10 material corresponds to the empiric formula x(M1/nXO2): y YO2: SiO2, wherein x has a value which is lower than 0.1, or can be equal to zero, y is lower than 0.1 and can be equal to zero; M is H or an inorganic cation with +n charge; X is a chemical element having an oxidation state +3 (Al, Ga, B, Cr) and Y is a chemical element with an oxidation state +4 (Ti, Ge, V). When x=0 and y=0, the material ITQ-10 can be described as a new polymorph form of microporous silica. The zeolithic material of the invention is characterized also by its X ray diffraction grating and its microporous properties. The preparation process is characterized by the use of one or various organic additives in a reaction mixture which is crystallized by heating.
摘要:
The present invention is directed to open-framework and microporous solids particularly well suited for use in catalysis and ion exchange. The microporous solids are constructed by using a salt template which can be readily removed without destroying the framework of the micropore. Various microporous solids can be formed having different geometric structures depending upon the templating salt used and the concentration. Examples of two compounds include Na2Cs[Mn3(P207)2]C1(1) and K2.02Cs2.90[Cu3(P207)2]Cl2.92(2). Compound 1 crystallizes in the space group C2/c with a=21.210(8), b=5.272(2), c=13.924(2) ANGSTROM , beta=119.04(2), and Z=4. Compound 2 crystallizes in the space group 14/mcm with a=b=18.001(3), c=13.530(4) ANGSTROM , and z=8. Both compounds have 3-D (Mn, Cu)-P-O frameworks. For 1, two Mn04, two Mn05 polyhedra and four P04 tetrahedra form small tunnels where Cs+ and Cl- ions reside. For 2, Cu04 and P207 groups form two different tunnels, one is similar to that in 1 (ca. 5.3 ANGSTROM in diameter) while the other formed by eight Cu04 polyhedra and eight P04 tetrahedra has an approximate diameter of 12 ANGSTROM .
