Abstract: Provided is an organic ligand-bound metal surface that selects one gaseous species over another. The species can be closely sized molecular species having less than 1 Angstrom difference in kinetic diameter. In one embodiment, the species comprise carbon monoxide and ethylene. Such organic ligand-bound metal surfaces can be successfully used in gas phase separations or purifications, sensing, and in catalysis.

Abstract: It has been found that strongly basic molecular sieves can be used to make stable, relatively selective catalysts for reactions between carbon- and hydrogen-containing species if the strongly basic molecular sieve is combined with a volatile transition metal carbonyl compound. Although the volatile transition metal compound preferably contains initially only a single transition metal atom, clusterification can convert this compound to a compound or ion of the formulaH.sub.a M.sub.b (CO).sub.c (I)where a, b, and c are nubers greater than zero but no more than about 15, 1 to 2 being typical for a and 3 to 4 being typical for b. The polynuclear (i.e. poly-metal atom) compounds of formula (I) are believed to be trapped within "supercages" of the molecular sieve structure. To obtain the strongly basic molecular sieve used as a starting material for making the catalyst, the molecular sieve is treated with an alkali metal azide and the azide is then decomposed.

Abstract: A Fischer-Tropsch catalyst comprising a particulate synthetic zeolite incorporating a transition metal catalyst reduced in situ by a preselected vaporous reductant metal, the method of catalytic manufacture and use.

Abstract: Solids have been prepared having very strongly acidic properties for hydrocarbon reactions. The solids are synthesized from anhydrous AlCl.sub.3 and a solid Bronsted acid.
