Abstract

The present invention provides a process and catalyst for the production of synthesis gas (a mixture of CO and H2) by reforming of methane with carbon dioxide. The process provides a direct single step selective vapor phase dry reforming of methane with carbon dioxide to produce synthesis gas over Ni—MgO—ZnO catalyst between temperature range of 600° C. to 800° C. at 1 atmospheric pressure. The process provides a methane conversion of 5-95% with H2 to CO mole ratio of 0.83-1.2.
