Abstract
Combined UBI-QEP/LHHW methodology was employed for kinetic modeling of carbon monoxide hydrogenation to light olefins on a bimetallic Fe–Co catalysis in a fixed bed micro-reactor. In combination with apparent activation energies obtained from UBI-QEP approach, the experimental data from central composite designs were employed to fit several LH/ER rate equations. A new rate equation for CO consumption and a new mechanism based on parallel formyl/carbide with two RDS elementary reactions was concluded. It was also concluded that CO* is MARI on Fe–Co catalysis surface and its coverage on the catalyst was estimated to be 0.5 ml.
