Abstract The catalytic performances of Pd catalysts supported on γ-Al 2 O 3 , α-Al 2 O 3 , and mixed phases Al 2 O 3 were investigated in the selective hydrogenation of acetylene in ethylene feed stream. It was found that the use of mixed phases Al 2 O 3 with approximately 64% of α-phase resulted in significant improvements in both acetylene conversion and ethylene selectivity. The presence of small amount of transition phase in the alumina supports brought about higher BET surface area and Pd… CONTINUE READING
