Abstract
The present invention relates to a novel heterogeneous catalyst for selective carbon dioxide methanation reaction having high activity and long-term stability, wherein the catalyst comprising of at least one alkali promoter metal, active metals selected from Nickel and Iron and a stable support for active metals having combination of CeO-γAlO. Further, the present invention provides a process for synthesis of said catalyst. Secondly, the present invention also provides a sustainable process for synthesis of methane using said novel heterogenous catalyst. The benefits of present invention are that it provides a sustainable COmethanation process as the novel outstanding catalyst having high performance and long-term stability and totally eliminates catalyst regeneration or reloading step due to its very long-term stability for >1000 h.
