Abstract
The present invention relate to a methane synthesis catalyst preparation method, comprising a preparation step for a catalytic body and a prereduction step. The prereduction step comprises: calcining the catalytic body to form a nickel aluminate spinel-containing catalyst precursor; and prereducing the catalyst precursor to acquire the methane synthesis catalyst. The catalyst prepared in the preparation method can be used in high-temperature and high liquid-to-gas ratio conditions, shows performance stability, and obviates the need for a further step of high-temperature reduction during vehicle operation. Also provided is the methane synthesis catalyst precursor. The catalyst precursor contains nickel aluminate spinel.
