摘要： A process for preparing a layered composition has been developed. The composition comprises an inner core and an outer layer comprising a molecular sieve. The process involves providing a slurry comprising inner core particles and sources of the framework elements of the molecular sieve. To this slurry there are added nutrient(s), i.e. framework element sources thereby forming crystals of the molecular sieve which agglomerate onto the inner core. The process is carried out for a time sufficient to form a layer of desired thickness.

摘要： A process for synthesizing a variety of molecular sieves has been developed. The process involves forming a reaction mixture comprising reactive sources of the framework elements plus at least one templating agent, reacting the mixture to at least partially crystallize the molecular sieve and provide a slurry of seed crystals and adding to it nutrients (sources) of the framework elements, e.g. aluminum and silicon in order to grow the seed crystals. The rate of addition of the nutrients is controlled such that it is substantially the same as the crystal growth rate and such that there is substantially no nucleation of new crystals. The seed crystals may be the same or different than the nutrients being added, thus allowing for a layered molecular sieve. When the crystals have reached a desired size, they are isolated by conventional techniques.

摘要： A process for preparing beads of various compositions has been developed. The process involves preparing a reaction mixture of sources of framework elements of a molecular sieve. The reaction mixture can optionally contain molecular sieve seeds. Additional sources of the framework elements are added to give a concentration above the critical supersaturation limit thereby forming beads. Depending on the composition of the reaction mixture and the reaction conditions one can obtain beads which are substantially amorphous, to beads that are substantially crystalline molecular sieve. These beads in turn can be further processed to deposit a molecular sieve layer onto the beads.

摘要： The present invention discloses mixed matrix membranes (MMMs) comprising ion-exchanged molecular sieves such as UZM-5 zeolite ion-exchanged with Li+ cation (Li-UZM-5) and a continuous polymer matrix and methods for making and using these membranes. These MMMs, comprising ion-exchanged molecular sieves, in the form of symmetric dense films, asymmetric flat sheets, asymmetric hollow fibers, or thin-film composites, have exhibited simultaneously increased selectivity and permeability (or permeance) over polymer-only membranes and the mixed matrix membranes made from molecular sieves that have not been ion exchanged for gas separations. These MMMs are suitable for a variety of liquid, gas, and vapor separations such as desalination of water by reverse osmosis, deep desulfurization of gasoline and diesel fuels, ethanol/water separations, pervaporation dehydration of aqueous/organic mixtures, CO2/CH4, CO2/N2, H2/CH4, O2/N2, olefin/paraffin, iso/normal paraffins separations, and other light gas mixture separations.

摘要： The present invention discloses method for making defect-free high performance mixed matrix membranes (MMMs) containing a continuous polymer matrix and dispersed molecular sieves such as AlPO-14 or UZM-5. These MMMs can be used for separations. The novel method for making defect-free high performance MMMs comprises: post treating the MMM at a temperature ≧150° C. This new method results in a MMM with either no macrovoids or voids of less than 5 angstroms at the interface of the continuous polymer matrix and the molecular sieves. The MMMs are in the form of symmetric dense film, thin-film composite (TFC), asymmetric flat sheet or asymmetric hollow fiber. These MMMs have good flexibility and high mechanical strength, and exhibit high carbon dioxide/methane (CO2/CH4) selectivity and high CO2 permeance for CO2/CH4 separation. The MMMs are suitable for a variety of liquid, gas, and vapor separations.

摘要： This invention presents a novel MgAPSO molecular sieve, containing a critical range of magnesium in the sieve framework and having a small crystallite size, which is particularly active for hydrocarbon conversion. The sieve advantageously is incorporated, along with a platinum-group metal, into a catalyst formulation which is useful for isomerization. When utilized in a process for isomerizing a non-equilibrium mixture of xylenes containing ethylbenzene, a greater yield of para-xylene is obtained compared to prior-art processes.

摘要： This invention involves a composition, a method of making, and an application of high plasticization-resistant chemically cross-linked polymeric membranes such as cross-linked cellulose acetate (CA) membrane. These cross-linked polymeric membranes with covalently interpolymer-chain-connected rigid networks showed no decrease in CO2/CH4 ideal selectivity under 690 kPa (100 psig) pure CO2 pressure and also no CO2 plasticization up to 3447 kPa (500 psig) pure CO2 pressure. By using the method of chemical cross-linking as described in this invention, the separation characteristics of the polymeric membranes can be decisively improved. These new cross-linked polymeric membranes can be used not only for gas separations such as CO2/CH4 and CO2/N2 separations, O2/N2 separation, olefin/paraffin separations (e.g. propylene/propane separation), iso/normal paraffins separations, but also for liquid separations such as pervaporation and desalination.
