Ni nano cluster support on MgO—CeO₂—ZrO₂catalyst for tri-reforming of methane and a process for preparation thereof

摘要

The present invention provides a Ni nano-cluster supported on MgO—CeO2—ZrO2 catalyst and processes the production of the catalyst. Further, the present invention discloses use of Ni nano-cluster supported on MgO—CeO2—ZrO2 catalyst for the synthesis gas (a mixture of CO and H2) by tri-reforming of methane. The process provides a direct single step selective vapor phase tri-reforming of methane to synthesis gas over NiO—MgO—CeO2—ZrO2 oxide catalyst between temperature range of 600° C. to 800° C. at atmospheric pressure. The process provides a methane conversion of 1-99% with H2 to CO mole ratio of 1.6 to 2.3.
