Nowadays our everyday life has been affected from the climate changes caused by CO2 emission. The primary objective of this study is to develop a robust and efficient catalyst to convert CO2 to value-added chemicals such as light olefins. A novel cobalt precursor was used to sythesize the cobalt carbide, which was then physically mixed with CeO2. The synthesized catalyst was tested for CO2 and H2 reaction in 1:3 mole ratio through a flow bed reactor at various temperatures (200~400°C) using on-line Gas Chromatagraphy (GC) analysis to determine the catalyst selectivity and conversion. The testing results showed encouraging selectivity for CO2 conversion to light olefins. Pulse CO Chemisorption, Temperature-programmed reduction (TPR), X-ray diffraction (XRD) and Thermogravimetric Analysis (TGA) were carried out with an aim to establish the activity and properties relations. This study will provide a significant insight to understand the role of CeO2 and Cobalt for CO2 conversion to light olefins.
