ABSTRACT

 

Nichel based catalysts were tested for carbon dioxide hydrogenation to methane at atmospheric pressure and in the temperature range between 350-550˚C. The catalysts with Ni loadings ranging from 12 to 22 %wt. were prepared by impregnation technique, characterized, and their performances were evaluated in CO2 conversion. The influence of the main parameters of catalytic reaction, such as reaction temperature, H2/CO2 molar ratio, Ni loading, GHSV and regeneration procedures was studied to obtain the optimum values for conversion and selectivity. The main experimental results (very high CO2 conversion together with almost total methane selectivity, obtained up to 400˚C) asserted the Ni/Al2O3-SiO2 as a potential catalyst for CO2 conversion.

This study is important to develop a possible technique of CO2 recycling and generating CH4 fuel.
