  CO₂ hydrogenation to methane over Zeolite promoted Ni/CeO₂ Catalysts at Atmospheric Pressure
  Author(s): Abdullahi Isah*
  
  The zeolite promoted Ni/CeO2 catalysts were constructed via impregnation method and applied for conversion of CO2 to methane at atmospheric pressure for the first time. The influence of calcination temperatures and operation conditions (such as reaction temperature, Gas Hourly Space Velocity (GHSV), H2/CO2 ratio) were studied. The results uncovered that the non-promoted 10 wt% Ni/CeO2 catalyst showed %CO2 conversion and %CH4 selectivity (about 99% CO2 conversion and 35.5% CH4 selectivity) and the zeolite (2-8 wt%) promoted 10 wt% Ni/CeO2 catalysts recorded (about 99% CO2 conversion and 0-17.6% CH4 selectivity) at 350 atmospheric pressure, gas hourly space velocity (GHSV) of 72000 SmL (gcat h)-1 and the H2/CO2 ratio of 4.
