Influence of zeolite type on activity of fischer-tropsch iron catalysts

The influence of zeolite type on the product composition, activity, and stability of a binary Fischer-Tropsch iron-containing catalyst was studied. It was shown that the redistribution of acid sites takes place during zeolite shaping with alumina, and, as a result, the relative amount of strong acid sites decreases and the proportion of medium-strength acid sites increases. Zeolites ZSM-5 and ZSM-12 appeared to be the most active in secondary reactions of hydrocarbon conversion under the conditions of hydrocarbon synthesis from CO and H2.
