The role of the zeolite in the hydrogenolysis of C2 and C3 hydrocarbons on RuNaY catalysts
(Elsevier, 1986-02)
The catalytic properties for the hydrogenolysis of ethane, propane and cyclopropane of a series of highly dispersed RuNaY catalysts have been investigated. These catalysts have activities and selectivities for ethane and ...
Model hydrodesulfurization catalysts: Solid state synthesis and characterization of iron containing molybdenum sulphide
(Elsevier, 1989)
Model catalysts for hydrodesulfurization were synthesized via solid state reactions of elemental sulfur with metallic iron and molybdenum powders. The starting materials had a general stoichiometry of Fe2[alpha]Mo1-[alpha]S2 ...
CO hydrogenation catalyzed by alumina-supported osmium: Particle size effects
(Elsevier, 1985-10)
Alumina-supported catalysts were prepared by conventional aqueous impregnation with [H2OsCl6] and by reaction of organoosmium clusters {[Os3(CO)12], [H4Os4(CO)12], and [Os6(CO)18]} with the support. The catalysts were ...
Metal dispersion of bimetallic catalysts via stepwise chemisorption and surface titration : I. Ru---Au/SiO2
(Elsevier, 1985-09)
A stepwise chemisorption and titration procedure involving H2 and O2 as adsorbates is used to measure the dispersion of the individual metal components in bimetallic Ru---Au/SiO2 catalysts. The experimental approach is ...

Gold-titania interactions: Temperature dependence of surface area and crystallinity of TiO2 and gold dispersion
(Elsevier, 1984-05)
The influence of temperature on the BET surface area, crystallinity, and anatase/rutile phase transformation of blank TiO2 and Au/TiO2 catalysts is studied. Presence of gold delays the recrystallization of anatase and the ...
Alumina-supported triosmium clusters and ensembles: Characterization by high-resolution transmission electron microscopy
(Elsevier, 1983-11)
Structurally defined supported osmium clusters [HOs3(CO)10---O---Al3(CO)12] with the -OH groups of [gamma]-Al2O3. The supported clusters were heated to 200 [deg]C in argon and then reduced in hydrogen at 400 [deg]C, being ...
Isotopic oxygen exchange on supported Ru and Au catalysts
(Elsevier, 1980-06)
The isotopic exchange reaction of molecular oxygen is applied to supported ruthenium and gold catalysts. The results on supported ruthenium are similar to those on RuO2. The exchange reaction seems to be unaffected by ...
The maximum melting temperatures in strain-crystallized van der waals networks
(Steinkopff-Verlag; Steinkopff ; Springer Science+Business Media, 1985-04)
A theory of strain-crystallization of random networks comprised of stereoregular chains is developed. The crosslinks are assumed to be expelled from crystal cores. For this reason, the rubber is considered to be represented ...
