| Outline of Final Research Achievements |
Due to shale-gas revolution, new process using methane as a natural resource instead of oil is highly demanded. In this research, we developed non-noble metal catalysts for dry reforming methane which is able to produce synthetic gas with lower H2/CO ratio than conventional methane steam reforming. At first, influence of Al3+ addition to Co-Mg-O solid solution catalyst was investigated. Addition of small amount of Al3+ increased reduction degree of Co2+ drastically and the catalysts shows high activity and stability for the reaction. However, when Al3+ amount is too large, it formed MgAl2O4, which results in decrease in the number of basic sites retarding coke formation. Furthermore, it was revealed that doping of small amount of SrO to the Co-Al-Mg-O solid solution catalyst is effective for further inhibition of coking. The catalyst exhibits high activity and stability in dry reforming under high pressure and low temperature, where coking is highly favored.
