Promotion effect of iron on Mo/Al2O3 catalyst for the CAMERE process
Journal Title: Advances in Environmental Sciences - International Journal of the Bioflux Society - Year 2012, Vol 4, Issue 2
Abstract
Reverse Water Gas Shift (RWGS) reaction is one of the main reactions that can be used to reduce greenhouse gases emissions. Through this reaction CO2 is converted to CO to produce beneficial chemicals such as methanol. In this paper Mo-Al2O3 catalyst was prepared and then promoted with Fe ions through co-impregnation method to produce Fe-Mo-Al2O3 catalyst. XRD tests were taken to determine the structure of the catalysts. Activity, selectivity and stability of both catalysts were investigated in a batch reactor and the results indicate that addition of Fe promoter to Mo-Al2O3 catalyst increased its activity and CO selectivity. Fe-Mo-Al2O3 showed acceptable catalytic stability during RWGS reaction. As a whole, Fe-Mo-Al2O3 can be a suitable candidate for RWGS reaction in CAMERE (carbon dioxide hydrogenation to form methanol via a reverse-water-gas-shift reaction) process.
