Abstract

A pulse-chromatographic method has been developed for the estimation of molybdenum surface by selective adsorption of oxygen at −78°C in cobalt-molybdenum-alumina catalysts. The surface concentrations of molybdenum in a series of catalysts of different compositions were compared with the activities for cyclohexene hydrogenation and for thiophene hydrogenolysis.

Abstract

Был разработан импульсно-хроматографический метод для определения поверхности молибдена по селективной адсорбции кислорода при −78°C на катализаторе кобальт-молибден-окись алюминия. Концентрация молибдена на поверхности в серии катали-заторов различного состава сравнивалась с активностями в процессе гидрирования циклогексена и гидрогенолиза тиофена.
