Study of syngas conversion to light olefins by statistical models.

Highlights: [•] Application of the response surface models in CO hydrogenation to light olefins has been studies. [•] Catalyst was a Fe–Co–Mn prepared with precipitation method. [•] A quadratic polynomial for CO hydrogenation and alkene yields was successfully fitted to the experimental data. [•] The RSM simulated data were also employed to kinetic study of CO hydrogenation. [•] A rate equation based on direct reaction of hydrogen from gas phase with molecularly adsorbed CO were proposed. [ABSTRACT FROM AUTHOR]
