ISSN: 1090-6533Source: Springer Online Journal Archives 1860-2000Topics: PhysicsNotes: Abstract Relaxation measurements are used to establish that for a concentration of gas-phase oxygen atoms n=1014 cm−3 heterogeneous recombination of oxygen atoms at the surface of copper and zinc sulfide takes place by a mechanism involving recombination of preadsorbed (precursor state) atoms. A hypothesis is put forward for the existence of a universal mechanism for the catalytic acceleration of heterogeneous chemical reactions.Type of Medium: Electronic ResourceURL: -

ISSN: 1090-6533Source: Springer Online Journal Archives 1860-2000Topics: PhysicsNotes: Abstract We consider the behavior of an α-iron alloy containing special molybdenum and tungsten carbides (MoC and WC) and oversized impurity atoms (Mo and W) in the solid solution. The effects of molybdenum and tungsten on the development of ballistic (cascade) processes in the alloy under reactor irradiation conditions have been studied by computer simulation methods to assess the possibility of substituting W for Mo in the alloy to obtain low-activated steels.Type of Medium: Electronic ResourceURL: -

The kinetic adsorption curves of the reactants and the rates of the heterogeneous chemical reaction were both determined for the first time as a result of direct measurements for the recombination of hydrogen atoms. As a result, the dependence of the reaction rate on the concentration of chemisorbed particles revealed that pre-adsorbed particles participate in the reaction.Type of Medium: Electronic ResourceURL: -

Published 1997Staff ViewISSN: 1090-6533Source: Springer Online Journal Archives 1860-2000Topics: PhysicsNotes: Abstract A series of experimental and theoretical investigations has been initiated for 6H-SiC samples sequentially implanted with high doses of N+(65 keV) + N+(120 keV)+Al+(100 keV)+Al+(160 keV) ions at temperatures between 200 and 800 °C. Nitrogen and carbon distribution profiles are measured by ERD and structural defect distributions are measured by Rutherford backscattering with channeling. A comparison between the experimental data and the results of computer simulation yields a physical model to describe the relaxation processes of the implanted SiC structure, where the entire implanted volume is divided into regions of different depth, having different guiding kinetics mechanisms.Type of Medium: Electronic ResourceURL: -

ISSN: 1090-6525Source: Springer Online Journal Archives 1860-2000Topics: PhysicsNotes: Abstract A theoretical analysis is offered for the formation and development of defects in silicon carbide implanted with nitrogen and aluminum ions and then annealed. The diffusion of defects, the formation of complexes, and the influence of the internal elastic stress fields produced by the implanted ions and the created complexes on the migration of interstials are taken into account. The computed distributions of defects agree satisfactorily with the experimental data. Certain kinetic parameters of silicon carbide are estimated numerically.Type of Medium: Electronic ResourceURL: -

Published 1993Staff ViewISSN: 1573-9171Keywords: propene ; oxidative acetoxylation ; acetic acid ; Pd-zeolite catalyst ; IR spectra ; potassium acetateSource: Springer Online Journal Archives 1860-2000Topics: Chemistry and PharmacologyNotes: Abstract The interactions between C3H6, AcOH and O2 were investigated on 1.5 % Pd/TsVM catalysts prepared with and without addition of 15 % AcOK. Three states for surface oxygen on the promoted catalyst were distinguished. Two of them are involved in the oxidation of AcOH and C3H6 to CO2 and H2O, whereas the adsorbed species of the third type participates in the formation of allyl acetate. The O/Pd ratios for the promoted catalyst fall in the range from 3 to 4, the nonpromoted system is characterized by an O/Pd value of 0.5. IR-spectral data are used to discuss the reaction scheme for the formation of allyl acetate.Type of Medium: Electronic ResourceURL: -

ISSN: 1573-9171Source: Springer Online Journal Archives 1860-2000Topics: Chemistry and PharmacologyNotes: Conclusions 1. The rate of hydrogenation of 2-methyl-2-butene on the Rb form of type Y zeolite is directly proportional to the partial pressures of the olefin and H2. 2. The kinetic equation of the hydrogenation reaction, derived on the basis of a scheme assuming the formation of an intermediate semihydrogenated complex, well describes the experimental data obtained.Type of Medium: Electronic ResourceURL: -

ISSN: 1573-9171Keywords: cyclohexene ; zeolites ; hydrogenationSource: Springer Online Journal Archives 1860-2000Topics: Chemistry and PharmacologyNotes: Abstract Hydrogenation of cyclohexene has been studied under pressure in a flow reactor on the following catalysts: Na- and H-forms of Y-type zeolites, erionite, magnesium and lanthanum oxides, palladium on silica and aluminum oxide. This reaction is accompanied by skeletal isomerization to give methylcyclopentane and methylcyclopentenes. The differences in activation energies for isomerization and hydrogenation reactions were estimated as 83–96 kJ/mole for NaY and Na,K-erionite, 33–50 kJ/mole for the H-forms of the zeolites, 33–37 kJ/mole on the Pd catalysts, and 25–33 kJ/mole on magnesium and lanthanum oxides. It is suggested that the cyclohexyl complex, formed as an intermediate during hydrogenation of cyclohexene on Na-forms of the zeolites, is neither a carbocation nor a radical.Type of Medium: Electronic ResourceURL: -

ISSN: 1573-9171Keywords: palladium ; zeolites ; allyl acetate ; Pd oxidation ; Pd reductionSource: Springer Online Journal Archives 1860-2000Topics: Chemistry and PharmacologyNotes: Abstract Palladium catalysts based on A, X, Y, chabazite, erionite, mordenite, TsVM, and TsVK zeolites are studied by the methods of temperature-programmed reduction and hydrogen desorption. Palladium is shown to be located in zeolite pores in all catalysts except Pd/mordenite for which 24 % of the palladium is located on the external surface of the zeolite. The dispersity of the palladium on the zeolites is determined by the amount of H2 evolved in the decomposition of the β-phase of PdH and by the value of the O/Pd ratio obtained by palladium oxidation in the 100 to 500 °C temperature range. According to the O/Pd ratio, the catalysts are divided into two groups: samples based on X, Y, chabazite, erionite, and mordenite (O/Pd=0.4 to 0.7), and catalysts containing A, TsVM, and TsVK zeolites (O/Pd=0.2 to 0.3). The catalysts of the first group are weakly active in the oxidative acetoxylation of propylene, while all of the catalysts of the second group except Pd/NaA are very active. The conclusion is drawn that the oxidation of palladium is not the limiting stage in the oxidative acetoxylation of propylene.Type of Medium: Electronic ResourceURL: -
