Abstract: A new crystalline molecular sieve designated SSZ-95 is disclosed. In general, SSZ-95 is synthesized from a reaction mixture suitable for synthesizing MTT-type molecular sieves and maintaining the mixture under crystallization conditions sufficient to form product. The product molecular sieve is subjected to a pre-calcination step, and ion-exchange to remove extra-framework cations, and a post-calcination step. The molecular sieve has a MTT-type framework and a H-D exchangeable acid site density of 0 to 50% relative to molecular sieve SSZ-32.

Abstract: We provide a method for removing contaminants from a gas, comprising: alternating input of the gas between two or more beds of adsorbent particles that comprise zeolite SSZ-36, zeolite SSZ-39, or zeolite SSZ-45; wherein the gas contacts one of the beds during an adsorption and a tail gas is simultaneously vented from another of the beds by desorption; wherein a contacting pressure is from about 345 kPa to about 6895 kPa and produces a product gas containing no greater than about 2 mol % carbon dioxide, at least about 10 wppm water, at least about 65 mol % of methane recovered from the feed gas, and at least about 25 mol % of ethane recovered from the feed gas; and wherein the tail gas is vented from the feed end of the beds. We also provide a method for removing a contaminant from a gas, wherein the gas contains hydrogen sulfide.

Abstract: Provided is a method of encapsulating a metal in a zeolite. The method comprises inserting a metal precursor into a parent zeolite, and then converting the parent zeolite to a zeolite having a higher framework density than the parent zeolite. The conversion is achieved without the need of an organic structure directing agent.

Abstract: A method is provided for synthesizing aluminosilicate zeolite SSZ-26 by interzeolite transformation.

Abstract: Zeolites having highly dispersed bimetallic clusters, uniformly distributed in size and composition, encapsulated therein are disclosed. Metal encapsulation and alloying is conferred by introducing ligated metal cation precursors into zeolite synthesis gels, which are subsequently crystallized hydrothermally to form zeolites with metal cations occluded in the pores. The ligated cations are anchored to the zeolite framework via siloxane bridges which enforces their uniform dispersion throughout the zeolite crystals. Treatment of the crystallized zeolites in O2 and then H2 forms bimetallic clusters, which remain narrowly distributed in size and composition.

Abstract: Provided is a method for preparing a zeolite having a Si/Al ratio of at least 10 by interzeolite transformation in the absence of an organic structure directing agent. The method is more cost effective and less equipment intensive as it eliminates the costly organic structure directing agent and the waste treatment at the plant.

Abstract: Crystalline molecular sieves and their synthesis using quaternary N-methyl-diisoalkylammonium cations as organic structure directing agents are disclosed. The structure directing agent has the following structure (1): in which R1 is selected from hydrogen, a methyl group, an ethyl group, a propyl group, and a hydroxymethyl group; and R2, R3, R4 and R5 are independently selected from a methyl group, an ethyl group, and a propyl group.

Abstract: Provided is a surfactant-free, single-step synthesis of delaminated aluminosilicate zeolites. The process comprises the step of heating a borosilicate zeolite precursor in a metal salt solution, e.g., an aluminum nitrate solution, zinc nitrate solution or manganese nitrate solution. The delaminated aluminosilicate zeolite product is then recovered from the solution.

Abstract: Provided is a method of alkylating an aromatic compound comprising contacting an aromatic compound and an alkylating agent in the presence of UCB-3 as a catalyst under reaction conditions suitable for aromatic alkylation. The aromatic compound preferably comprises benzene or toluene and the alkylation agent preferably comprises an olefin or alcohol. Lower temperature ranges can be used for the reaction, for example in the range of from 100 to 300° C.
