Light olefins are considered the backbone of chemical industry, and a broad variety of derivatives, used in our daily lives, are produced from these building blocks. Notably, it is estimated that the C2-4= demand will face an annual growth of 3.5% by 2030, as a combined result of global population growth and rising living standards. The current leading technology for light olefins production is the steam cracking of natural gas and/or crude oil fractions but this process is linked with a high carbon footprint. Concerns associated with the depletion of fossil fuels and the threat of global warming have recently initiated efforts to explore alternative pathways and feedstocks to produce light olefins through COX hydrogenation by employing either excess RES-powered electrolytic hydrogen combined with captured CO2 industrial emissions or syngas mixtures generated through biomass gasification or biofuels reforming. Therefore, the present work aims to examine the thermodynamic aspects of the COX hydrogenation to light olefins at a range of temperatures and pressures of industrial practice by feeding several carbon-neutral COX-H2 mixtures. For this end, the Aspen Plus software and the Gibbs free energy minimization method have been compiled in a series of simulation scenarios.
