摘要: |
The present study aims at exploring a concept which can convert coal-bed methane (containing methane, air and carbon dioxide) to synthesis gas. Without pre-separation and purification, the low-cost synthesis gas can be produced by coupling air partial oxidation and CO2 reforming of coal bed methane. For this purpose, the co-precipitated NieMgeZrO2 catalyst was prepared. It was found that the co-precipitated Ni-Mg-ZrO2 catalyst exhibited the best activity and stability at 800 oC during the reaction. The conversions of CH4 and CO2maintained at 94.8% and 82.1% respectively after 100 h of reaction. The ffect of reaction temperature was investigated. The H2/CO ratio in the product was mainly dependent on the feed gas composition. By changing O2/CO2 ratio of the feed gases, the H2/CO ratio in the offgas varied between 0.8 and 1.8. The experimental results showed that the high thermal stability and basic properties of the catalyst, and the strong metal-support interaction played important roles in improving the activity and stability of the catalyst. With the combined reactions and the Ni-Mg-ZrO2 catalyst, the coal bed methane could be converted to synthesis gas, which can meet the need of the subsequent synthesis processes. |
