FISHER-TROPSH SYNTHESIS Russian patent published in 2018 - IPC C10G2/00 

FIELD: chemistry.

SUBSTANCE: invention relates to Fischer-Tropsch synthesis. Fischer-Tropsch synthesis process includes feeding gaseous reactants including at least CO, H₂ and CO₂, into a reactor containing an iron-based catalyst, where H₂ and CO are fed in a molar ratio of H₂ : CO of at least 2:1, and CO₂ and CO are fed in a CO₂:CO ratio of at least 0.5:1; controlling the operating temperature of the reactor in the range from 260 °C to 300 °C, withdrawal of liquid product and gaseous product containing hydrocarbons, CO, H₂, water and CO₂, from the reactor; wherein approximation to the equilibrium of the steam reforming in the gaseous product withdrawn from the reactor according to equation 5 is less than 0.9,

where T is the operating temperature of the reactor in kelvin, and P is the partial pressure of gases CO, CO₂, H₂ and water vapour in the gaseous product.

EFFECT: process is characterised by low selectivity of the formation of carbon dioxide without the need for a large amount of carbon dioxide in the feed gas for Fischer-Tropsch synthesis.
