- 摘要：
- The catalytic properties of Ni, Co, and Co-Ni supported activated carbon (AC) catalysts for oxidation for the removal of carbon monoxide (CO) in H2-rich gas are investigated. Results show that CoxOy/AC and CoO–NiO/AC exhibit higher catalytic activity than NiO/AC and that CoO–NiO/AC gives high CO conversion of above 99.5% at a wide reaction temperature region of 413–463 K. The addition of nickel oxide (NiO) can lead to enriched CoO species on the surface of CoO-NiO/AC. The higher catalytic activity and selectivity of CoO-NiO/AC compared with CoxOy/AC can be attributed to NiO playing an important role.
