Abstract: A method of separating and selectively removing hydrogen contaminant from hydrogen-containing product and by-product process streams is disclosed. Separation and removal occur when certain Cd containing zeolite, silica, alumina, carbon or clay compositions are placed in contact with a hydrogen-containing process stream. A hydrogen-encapsulated composition is formed by practice of the method. Also disclosed is a reversible storage method for hydrogen using the above-described compositions.

Abstract: A method for making monomethylamine, dimethylamine and trimethylamine, in which methanol and/or dimethylether and ammonia are contacted in the presence of an acidic zeolite chabazite catalyst is disclosed. The method suppresses the production of trimethylamine and optimizes dimethylamine and monomethylamine yields.

Abstract: A method of separating and selectively removing hydrogen contaminant from hydrogen-containing product and by-product process streams is disclosed. Separation and removal occur when certain Cd-exchanged zeolite rho compositions are placed in contact with a hydrogen-containing process stream. A hydrogen-encapsulated zeolite rho composition is formed by practice of the method.

Abstract: The present invention relates to the selectivity of production of methylamines from methanol and/or dimethylether and ammonia using at catalytic amount of acidic molecular sieve.

Abstract: When small amounts of zeolite or titanosilicates are added to thermotropic liquid crystalline aromatic polyester, poly(ester-amide) or poly(ester-imide) compositions, the compositions become less flammable. In many cases addition of the zeolite or titanosilicates does not significantly affect other properties of the composition, which may be used as molding resins, for instance to make parts useful in the electrical, electronic or automotive industry.

Abstract: This invention provides an attrition resistant catalyst composition and method for producing such composition. The catalyst is comprised of an acidic zeolite, rho or chabazite, and a particulate binder, kaolin, bentonite, alpha-alumina, or titania, which can be optionally modified by treatment with a compound containing Si, Al, P or B. This invention further provides a process for producing methylamines, preferably dimethylamine, comprising reacting methanol and/or dimethyl ether and ammonia in the presence of a catalytic amount of an attrition resistant catalyst of the invention.

Abstract: A process is disclosed for producing HCFC-133a which includes reacting certain trihaloethene starting materials (e.g., trichloroethene) with HF in the gaseous phase at an elevated temperature in the presence of certain supported metal catalysts containing effective amounts of zinc. A catalyst of metal fluoride on a fluorinated alumina support having an atomic ratio of F to Al of at least 2.7:1 and containing .beta.-aluminum fluoride, is employed.

Abstract: Novel Cd-exchanged rho compositions and compositions of zeolite rho encapsulated with hydrogen made therefrom are disclosed. The Cd-exchanged zeolite rho compositions are useful in separating and selectively removing hydrogen from hydrogen-containing process streams and storing the separated hydrogen therein. Encapsulation of hydrogen can be accomplished in large amounts even at pressures of 1 atmosphere.

Abstract: A process is disclosed for the dehydrohalogenation of partially halogenated ethanes of the formula C.sub.2 H.sub.a Cl.sub.b F.sub.c where a is an integer from 1 to 4, b is an integer from 0 to 3 and c is an integer form 1 to 5 to produce olefins selected from the group consisting of C.sub.2 H.sub.a-1 Cl.sub.b-1 F.sub.c and C.sub.2 H.sub.a-1 Cl.sub.b F.sub.c-1. The process involves contacting C.sub.2 H.sub.a Cl.sub.b F.sub.c with a zeolite selected from the group consisting of NaX and CsY. Selective reaction of one isomer from a mixture of two isomers is disclosed as a means for purification of the relatively unreactive isomer. Also disclosed is a process for producing perfluorocyclobutane which involves contacting CHF.sub.2 CClF.sub.2 with such zeolites.

Abstract: Mixtures of CClF.sub.2 CF.sub.3 (CFC-115) and CHF.sub.2 CF.sub.3 (HFC-125) can be substantially separated by using carbon nanotubes as a sorbent for CClF.sub.2 CF.sub.3. A process is described for treating a starting mixture of CHF.sub.2 CF.sub.3 and CClF.sub.2 CF.sub.3 to provide a product wherein the mole ratio of CHF.sub.2 CF.sub.3 to CClF.sub.2 CF.sub.3 is increased relative to the mole ratio of CHF.sub.2 CF.sub.3 to CClF.sub.2 CF.sub.3 in the starting mixture; and another process (involving desorbing sorbed CClF.sub.2 CF.sub.3) is disclosed for treating a starting mixture of CClF.sub.2 CF.sub.3 and CHF.sub.2 CF.sub.3 to provide a product mixture wherein the mole ratio of CClF.sub.2 CF.sub.3 to CHF.sub.2 CF.sub.3 is increased relative to the mole ratio of CClF.sub.2 CF.sub.3 to CHF.sub.2 CF.sub.3 in the starting mixture. The process for producing a CHF.sub.2 CF.sub.3 -enriched product and the process for producing a CClF.sub.2 CF.sub.3 -enriched product may be integrated into an overall process (e.g.
