Hybrid catalysts (Cu-Al-SBA-15)forDME steam reforming; Deactivation and regeneration |
| 초록 |
The deactivation and regeneration behaviors of the hybrid catalyst (Cu-Al-SBA-15)forDME steam reforming were conducted in various conditions. The deactivation of the hybrid catalysts could be inhibited by increasing the ratio of steam/DME, lowering the space velocity, or reducing the reaction temperature. A higher ratio of Cu/Al could also prolong the life of the hybrid catalysts.The regeneration treatment with air at 500 ~ 700 oC could recover the catalytic performance of the deactivated catalysts as the fresh catalyst. Its effect was due to the redispersion of metallic Cu as well as the removal of carbon deposit by burning. |
