Abstract

The effects of Na+ ions on the physicochemical properties and catalytic activity of CoMo/γ-Al2O3 hydrodesulfurization catalysts prepared by inverse impregnation has been studied. The catalytic activity was found to be almost independent of the priority of impregnation, it is correlated with the distribution of promoter species in the oxidic precursors as well as with the selectivity of the catalysts. The Na doping of the support brings about a progressive decrease in the catalytic activity due to the partial scavenging of MoVI by Na+ to form Na2MoO4.

Abstract

Были исследовани эффекты ионов Na+ на физико-химические свойства и каталитическую активность катализаторов гидродесульфурирования. CoMo/γ-Al2O3, приготовленных инверсным импрегнированием. Каталитическая активность почти не зависит от очередности импрегнирования. Она коррелируется с распределением промоторных частиц в окисляющих предшественниках, а также с селективностью катализаторов. Дотирование носителя натрием приводит к прогрессивному уменьшению каталитической активности, вследствие частичного захвата MoVI ионами Na+, образуя Na2MoO4.
