Catalytic tests of the above mentioned catalysts with 1 wt%, 5 wt% and 10 wt% Fe loading were carried out in a fixed bed reactor at temperatures between 30 °C and 90 °C and a pressure of 22.5 bar aiming to model industrial front-end conditions of an acetylene removal unit. The feed composition is given in Table . The observed product spectrum and the reaction pathways are shown below (Scheme 1). In general, catalysts with low selectivity towards ethane and the oligomerization products are suitable for the acetylene hydrogenation.
