Abstract

The present invention provides a coke resistant catalyst and process for sequestration of carbon dioxide via reforming of methane to synthesis gas (a mixture of CO and H2). The process provides a direct single step selective vapor phase carbon dioxide reforming of methane to syngas over gadolinium promoted mesoporous Ni-ZSM catalyst. The process provides almost 11-95% conversion of methane with H2 to CO ratio of 0.82 to 1.
