Abstract

The promotion of rhenium on cobalt catalysts prepared by various methods has been investigated in the CO hydrogenation. 10 at.% rhenium was added to Co/NaY sample and 10 at.% with 90 at.% Co bimetallic samples were prepared by sol/gel technique. The samples pretreated in various manner revealed an about five fold increase in activity and an increase in the chain length in the NaY supported sample while the activity and selectivity changed in various way in the sol/gel prepared samples. In the mechanism the rhenium provides an action preventing fast deactivation of cobalt.
