Reforming of methane with CO2 over Ni nanoparticle supported on mesoporous ZSM-5

Ni-nanoparticle supported on mesoporous ZSM-5 was prepared by dispersing colloidal Ni-nanoparticle over mesoporous ZSM-5. The resulting material was found thermally stable even at 900 °C and has uniform pore diameter of around 5 nm. The material was characterized by XRD, FE-SEM, TEM, XPS, TPR and N2 adsorption/desorption. Reforming of methane with CO2 was performed over Ni supported on mesoporous ZSM-5 at atmospheric pressure. The catalyst shows 96.2% methane conversion at 800 °C with the production of synthetic gas with the H2/CO mole ratio of 1:1. Various reaction parameters like temperature, weight hour space velocity (WHSV), Ni loading and time on stream were also studied.
