Removal of carbonaceous matters over alumina supported chromium and platinum chromium catalysts

Platinum, both alone and with a low and high amount of chromium as an additive supported on alumina, was studied as a catalyst. These catalysts were examined in the removal of the carbonizate as a model material. It was found that the 2Cr/Al₂O₃ catalyst showed a significant increase in the catalytic activity as compared to 20Cr/Al₂O₃. An addition of platinum was found to cause a decrease of activity.
