Global warming has become an issue concerning the emission of CO2 which is a greenhouse gas. Methane is a major component of natural gas which is inexpensive and very attainable. Combining CO2 and CH4 in a single process to produce value added chemicals is very desirable. The primary objective of this study is to develop novel iron based catalysts to enhance the reaction of CO2 with CH4. The heterogeneous Fe-based bimetallic and trimetallic catalysts were synthesized via a wet incipient impregnation method to uniformly coat the metal salts to the pre-treated support (SiC, SiO2 and ZrO2). The catalyst was dried in the oven at 80° C for two hours before subjected to the furnace to calcine at 450° C for five hours. The synthesized catalysts were tested for CO2 dry reforming with methane through a flow bed reactor with controlled CO2 and CH4 flow rate and on-line GC analysis to determine the catalyst performance such as selectivity, conversion and stability. Pulse CO Chemisorption was performed to compare the number of active sites in each supported catalysts and Temperature-programmed reduction (TPR) was carried out to compare the reducibility of active metals in supported catalysts and to exame the alloy formation of the bi- and tri-metallic catalysts. Catalyst characterization such as Brunauer Emmett Teller (BET) surface area, pore size and volume, Transmission Electron Microscope (TEM), X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD) are to be carried out with an aim to establish a relationship between activity and properties. The fundamental study will serve as great guidance for us to understand the reaction pathway of dry reforming of CO2 with CH4.
