The suggested approach was applied for kinetic modeling of the process of CO2 hydrogenation into hydrocarbons using real experimental data. It is generally accepted that the process of CO2-FT synthesis proceeds in two stages: the RWGS reaction followed by CO hydrogenation via FT mechanism. Besides, an additional pathway of direct CO 2 hydrogenation to methane, also known as the Sabatier reaction, occurs over Fe-based catalysts that was suggested in the works . Thus, the following reaction set was used for building the model: The reaction of CO hydrogenation via FT mechanism has a kinetic limitation. The mass fraction 𝑊 𝑛 (𝑛carbon number) of hydrocarbons (or alcohols) in the products can be described by the Anderson-Schulz-Flory (ASF) distribution :
