Abstract

High energy consumptions of worldwide energy resulted on the increasing demand of fossil fuels and endanger its natural reserve. High use of fossil fuels in industrial sector and transportation leading to the high concentration of CO2 in the atmosphere cause the global warming and greenhouse effects. In this study with the aim to help preventing the problem and offer other alternatives for fossil fuels, CO2 methanation process is the most suitable with the presence of catalysts and support. Monometallic and bimetallic catalysts with different compositions of Ni and Co using SiO2 have been prepared using co-precipitation method. Monometallic catalysts is the 100% composition of Ni and Co itself with SiO2 as their support, meanwhile bimetallic catalysts of NiCo with the composition of 80/20, 50/50 and 20/80, respectively. The studies of the physical and chemical properties of these five sampled catalysts done by TGA and FTIR analysis with the Ni as the main catalysts for CO2 methanation due to its advantages and more economical for industrial purpose. From this study, it can be concluded that combination of NiCo with 80/20 composition is the most suitable for CO2 methanation. High composition of Ni is better and Co as secondary catalysts helps to prevent the sintering and deactivation of Ni catalysts at reaction condition for CO2 methanation with SiO2 as their support.
