    Description / Table of Contents: Abstract Импульсным и калориметрическим методами изучены зависимоти скоростей окисли-тельной дегидродимеризации и полного окисления пропилена и энергии связи кисло-рода от степени восстановления висмутоловянного окисного катализатора. Показано, что в стационарном состоянии поверхность образца восстановлена на 80% и характе-ризуется наличием однородного кислорода с прочностью связи 90 ккап/моль.
    Notes: Abstract The effect of the extent of reduction of a bismuth-tin oxide catalyst on the rate of oxidative dehydrodimerization and total oxidation of propylene and on the oxygen binding energy has been studied by pulse and calorimetric techniques. It is shown that the steady state surface is reduced by 80% and is characterized by the presence of one type of oxygen with a binding energy of 90 kcal/mol.

    Description / Table of Contents: Abstract С помощью микрокалориметра Кальве изсмерены дифференциальные теплоты адсорбции кумола при 293 К на Ca-, Sr, Ba-формах метакаолинита при степенях заполнения поверхности до 0.1. Показано наличие звух знергетически различных типов адсорбционных центров. Начальные теплоты адсорбции обусловлены приподой обменного катиона, причём теплоты адсорбции уменьшаются в ряду Ba, Sr, Ca, Mg.
    Notes: Abstract Differential heats of cumene adsorption at 293 K on Ca-, Sr- and Ba-substituted metakaolinites at surface coverages up to 0.1 have been measured on a Calvet microcalorimeter. The presence of two energetically different adsorption centers are shown to be determined by the nature of the exchanged cation; the adsorption heats decrease in the sequence Ba, Sr, Ca, Mg.

    Description / Table of Contents: Abstract Раздельно адсорбированный на ССГ-М прочно связанный кислород инертен по отношению к H2. В катализе, при одновременном присутствии O2 и H2, участвует слабо связанная форма кислорода. каталититическая реакция оказывает “защитное” деиствие на ССГ-М, препятствуя прочной диссоциативной хемосорбции кислорора.
    Notes: Abstract Strongly bound oxygen separately adsorbed on LCG-M is inert with respect to H2. In catalysis with the simultaneous presence of O2 and H2, a weakly bound (presumably, molecular) form of oxygen participates. Catalytic reaction exerts a “protective” effect on LCG-M, inhibiting the strong dissociative chemisorption of oxygen.

    Description / Table of Contents: Abstract Сделано сравнение теплот адсорбции кислорода на железо- и хром-молибденовых катализаторах, приведенных в стационарное состояние при окислении метанола с одинаковыми концентрациями реагентов в газовой фазе. Показано, что при высокой энергии связи кислорода (75–90 ккал/моль) активность катализатора зависит в основном от активации молекулы метанола при её адсорбции. Величина изменения теплоты адсорбции по мере покрытия поверхности кислородом не влияет существенно на избирательность.
    Notes: Abstract A comparison was made of the heat of oxygen adsorption on iron- and chromium-molybdenum catalysts brought into a stationary state in methanol oxidation with the same concentration of reactants in the gas phase. It has been shown that at high oxygen binding energy (75–90 kcal/mol) the catalyst's activity depends mainly on methanol activation during its adsorption. Variations in the heat of oxygen adsorption with surface coverage do not appreciably affect the selectivity.

    Description / Table of Contents: Abstract Нанесенные платинаоловянные катализаторы адсорбируют водород при 330 K, по крайней мере, в двух формах: слабой с энергией связи порядка 50–70 кДж/моль и прочной с энергией связи более 100 кДж/моль. Слабая форма на поверхности медленно переходит в прочную.
    Notes: Abstract It has been established that supported Pt−Sn catalysts adsorb hydrogen at 330 K at least in two forms. They are weak and strong forms with the binding energies of about 50–70 and above 100 kJ/mol, respectively. On catalyst surface weak forms transform into strongly bound hydrogen.

    Description / Table of Contents: Abstract На нормальном молибдате кадмия продуктами окисления метанола являются в основном CO2 и H2. После введения в него избыточной MoO3 до соотношения Mo/Cd=1, 2 окисление метанола идет до формальдегида и окиси углерода по последовательной схеме. Энергия связи кислорода в стационарном состоянии для 1-го образца на 30 ккал/моль выше, чем для второго, а энергии активации скоростей превращения метанола, соответственно, равны 11,5 и 20 ккал/моль.
    Notes: Abstract On normal cadmium molybdate the products of methanol oxidation are primarily CO2 and H2. After the introduction of excess MoO3 to reach Mo/Cd=1.2, methanol is oxidized to formaldehyde and carbon monoxide via a consecutive scheme. The oxygen binding energy in the steady state for the first sample is by 30 kcal/mol higher than that for the second catalyst. The activation energies of methanol conversion are 11.5 and 20 kcal/mol, respectively.
