The Promoting Effect of Ru and Re Addition to Co/Nb2Os catalyst in the Fischer-Tropsch Synthesis

The promoting effect of Ru and Re addition to Co/Nb2Os catalyst in the Fischer Tropsch Synthesis was studied. The catalysts were characterized by TPR, XRD and H2 chemisorption. The Re and Ru addition increased both the activity and the Cs § selectivity by different mechanisms. Re prevented the cobal...

Description
Summary:The promoting effect of Ru and Re addition to Co/Nb2Os catalyst in the Fischer Tropsch Synthesis was studied. The catalysts were characterized by TPR, XRD and H2 chemisorption. The Re and Ru addition increased both the activity and the Cs § selectivity by different mechanisms. Re prevented the cobalt agglomeration whereas Ru increased the Co ~ site density. The Ru addition to Co/Nb2Os catalyst promoted diesel selectivity in the F.T.S. while the Re addition promoted the diesel as well as the gasoline one.
