    Description / Table of Contents: Abstract Катализаторы Pt-Sn/Al2O3, Pt/Al2O3 и Sn/Al2O3 тестировали в реакции разложения изопропанола. Дегидратирующую активность связывали с кислотностью катализаторов. Для Pt/Al2O3 и биметаллических катализаторов обнаружена подобная дегидрирующая активность, однако, для монометаллических катализаторов скорость дезактивации была измерена, а для Pt-Sn/Al2O3 не обнаружена.
    Notes: Abstract Pt−Sn/Al2O3, Pt/Al2O3 and Sn/Al2O3 catalysts were tested for isopropanol decomposition. Dehydration activity was related to catalysts acidity. Pt/Al2O3 and bimetallic catalysts show a similar dehydrogenation activity, however, monometallic catalysts have a deactivation rate non-observable in Pt−Sn/Al2O3.

    Oxidative coupling of methane over supported oxides promoted with alkali metals (1989)
    Springer
    Reaction kinetics and catalysis letters 39 (1989), S. 175-179

    Description / Table of Contents: Abstract Исследовано окислительное присоединение метана на Pr6O11, Mn2O3 и SnO2, нанесенных на α-Al2O3, а также тех же самых окислов, промотированных щелочными металлами. Добавка щелочи не только модифицирует активность и селективность к C2 как носителя, так и окиси металла, но приводит также к дополнительным эффектам.
    Notes: Abstract Oxidative coupling of methane over Pr6O11, Mn2O3 and SnO2 oxides supported on α-Al2O3 and the same oxides but promoted with alkali metals has been studied. Alkali addition not only modifies the activity and selectivity to C2 of the support and the metal oxide, but also an additional effect is observed.

    Performance of Pt−Re/Al2O3 catalysts with different radial distribution profiles (1987)

    Description / Table of Contents: Abstract Катализатор Pt−Re/Al2O3, приготовленный при различных условиях пропитки, характеризовали с помощью ТПВ и тестировали в реформинге лигроина и н-гептана. Наблюдались различные распределения радикалов Pt и Re и профилей восстановления на катализаторах. Когда оба металла взаимодействуют, после ступени дезактивации наблюдались повыщенные дегидроциклизация и конверсия, в то время как разделение Re от Pt не оказывает отрицательного эффекта на каталитическую активность.
    Notes: Abstract Pt−Re/Al2O3 prepared under different impregnating conditions were characterized by TPR and tested in naphtha and n-heptane reforming. Catalysts showed different Pt and Re radial distributions and reduction profiles. When both metals interact, higher dehydrocyclization and conversion are retained after a deactivation step, meanwhile, when Re is segregated from Pt the catalytic performance is negatively affected.

    Effect of acid treatment on the properties of an activated carbon (1989)
    Springer
    Reaction kinetics and catalysis letters 40 (1989), S. 331-335

    Topics: Chemistry and Pharmacology
    Description / Table of Contents: Abstract Увеличение активности углерода, обработанного HF, является результатом сильного уменьшения количества его неорганических примесей, что приводит к увеличению поверхностной площади углерода, более сильному взаимодействию Pt-C и более высокой дисперсности Pt.
    Notes: Abstract The enhancement of the activity of a carbon treated with HF is due to the drastic diminution of its inorganic impurities, which produces an increase of the surface area of the carbon, a stronger Pt-C interaction and a higher Pt dispersity.

    Description / Table of Contents: Abstract Исследована каталитическая конверсия природного газа до углеводородов C2 при давлении 1 атм. и в интервале температур 400–700° C, используя некоторые металлические окислы, нанесенные на Al2O3 и SiO2. Анализировали влияние времени местопребывания на селективность. Окислы Mn, Sn, Pb, Bi и Th обладают высокой селективностью к углеводородам C2.
    Notes: Abstract Catalytic conversion of natural gas to C2 hydrocarbons at 1 atm and temperatures between 400 and 700 °C, using several metallic oxides supported on Al2O3 and SiO2 was studied. The effect of the residence time on the selectivity is also analyzed. Mn, Sn, Pb, Bi and Th oxides show a high selectivity to C2 hydrocarbons.

    ISSN: 1588-2837
    Source: Springer Online Journal Archives 1860-2000

    Notes: Abstract The hydrogenation activity of Pt supported on activated carbon would depend on both the Pt dispersity (which can be modified by a partial carbon burn-off in air) and the impurities concentration.
