摘　　要：Several supported Pd catalysts were prepared and their catalytic activity for selective oxidation of hydrogen was studied. The results show that the variety of the supports has great effect on the catalytic activity. The space velocity and the Pd loading show also certain influence. The most active catalyst Pd/C A can selectively remove H 2 at 170～200℃ and 1?800 h -1 from a feed gas consisting of H 2 (0 197%), O 2 (0 103%), CO (40%) and N 2 (balance). When CO content in the feed gas increases to 78%, the activity of the catalyst only decreases a little, indicating that the results obtained here seems applicable to the removal of H 2 from pure CO.Several supported Pd catalysts were prepared and their catalytic activity for selective oxidation of hydrogen was studied.
