The catalytic tests were performed in a continuous-flow fixed-bed reactor at 10 bar. The oven containing the reactor was heated to a set temperature (T oven ) of 50, 100, or 150 • C. The applied feed contains a H 2 :C 2 H 2 :C 2 H 4 ratio of 5:1:1. The acetylene conversion (X C2H2 ) was evaluated as
