(Texas A&M University. Libraries, 1976)The catalytic activity of Cu(II)NaY zeolites in the oxidation of ammonia by molecular oxygen and by nitric oxide has been investigated for a series of copper-exchanged Y zeolites. Kinetic data were determined for the ...
-
(Texas A&M University. Libraries, 1979)The recent demands on the avialable energy have stimulated the search for alternatives to oil. Methanol, because of its abundance and the availability of technology to produce it from coal, is projected as an alternative ...
-
(Texas A&M University. Libraries, 1990)Ruthenium metal on a zeolite support was found to be active for the catalytic synthesis of ammonia from dihydrogen and dinitrogen at temperature between 300 and 450°C and at atmospheric pressure. A triply-promoted iron ...
-
(Texas A&M University. Libraries, 1982)The characterization of several molybdenum zeolites was facilitated using X-ray photoelectron spectroscopy. Samples prepared from the reaction of Mo(CO)(,6) with ultrastable zeolites exhibited superficially high concentrations ...
-
(Texas A&M University. Libraries, 1981)The decomposition of the {Ru(NH(,3))(,6)}('3+) complex in both X- and Y-type zeolites was investigated using several techniques including EPR spectroscopy, infrared spectroscopy, and Electron Spectroscopy for Chemical ...
-
(2023-07-06)Porous crystalline materials are highly valued for their exceptional capabilities in separation, catalysis, and ion exchange. In particular, zeolites are nanoporous tetrahedral aluminosilicate crystal frameworks with ...
-
(Texas A&M University, 2005-11-01)Hierarchically ordered porous oxides have garnered much interest because of the numerous applications that can be developed from these materials. The catalytic properties, separation ability, and ion exchangeability of ...
-
(Texas A&M University. Libraries, 1977)The catalytic activity of supported ruthenium and a series of supported ruthenium-nickel and ruthenium-copper alloys were investigated for the reaction of carbon monoxide with hydrogen to form methane. Kinetic data were ...
-
(Texas A&M University. Libraries, 1992)Zeolites are inorganic solid acids which arc important in many industrial heterogeneous catalysis processes involving chemical transformations of hydrocarbons. The Bronsted acidity of a particular zeolite determines its ...
-
(Texas A&M University. Libraries, 1979)The selective oxidation of olefins including oxidative dehydrogenation and epoxidation reactions over transition metal-exchanged zeolite. Y at mild reaction conditions was investigated. This dissertation describes the ...
-
(Texas A&M University, 2006-04-12)Complex reaction kinetics of the solid acid alkylation of isobutane with butenes over a proton-exchanged Y-zeolite has been modeled at the elementary step level. Starting with a computer algorithm that generated the reaction ...
-
Solid-state nuclear magnetic resonance studies of the reactions of olefins within zeolite catalysts (Texas A&M University. Libraries, 1990)Olefins are one of several classes of organic compounds which undergo acid-catalyzed reactions within acidic zeolite catalysts. Reactions of olefins are of considerable interest in heterogeneous catalysis since they ...
-
(Texas A&M University. Libraries, 1985)Olefins represent the starting point in the formation of the majority of the petrochemical products. The components can be polymerized, copolymerized, and selectively oxidized to a large number of useful products. As crude ...
-
(Texas A&M University. Libraries, 1991)The National Aeronautics and Space Administration is developing a Controlled Ecological Life Support System (CELSS) for use at a lunar outpost or Mars colony. Plants are an important component of a CELSS because they will ...
