Abstract

The process was carried out over Co/Al catalysts containing oxides of alkali metals (Li, Na, Rb, Cs) as additives. The presence of alkali metals generally decreases the activity of the Co/Al catalysts, except for very low concentrations of Li, Na, Rb and Cs atoms. Activity of catalyst increases with atomic weight of alkali metal additive. Possible effect of additive on catalyst structure is briefly discussed with respect to catalyzed process.

Abstract

Реакция проводилась над катализаторами Co/Al, содержащими щелочные металлы (Li, Na, Rb, Cs) в качестве добавки. Присутствие щелочных металлов обычно уменьшает активность кчтализатора Co/Al, за исключением очень низких концентраций атомов Li, Na, Rb и Cs. Активность катализатора увеличивается с повышением атомного веса шелочного металла — добавки. Возможный эффект добавок на структуру катализатора обсуждается, исходя из особенностей катализированного процесса.
