FIELD: technological processes.

SUBSTANCE: invention relates to Fischer-Tropsch synthesis. Method of carrying out the Fischer-Tropsch synthesis involves a chloride-alkali process, while the overall method includes: 1) gasification of the source material with the aim of obtaining raw synthesis gas for the synthesis of Fischer-Tropsch containing H₂, CO and CO₂; 2) electrolysis of a saturated solution of NaCl using an industrial chloride-alkali process in order to obtain a solution of NaOH, Cl₂ and H₂; 3) CO₂ removal from raw synthesis gas using the NaOH solution obtained in step 2) in order to obtain pure synthesis gas or in step 3) CO₂ first separated from the raw synthesis gas to produce pure synthesis gas, and then CO₂ absorbed in an aqueous solution of NaOH obtained in stage 2); 4) injection of H₂, obtained in stage 2) into pure synthesis gas in order to regulate the molar ratio CO/H₂ in pure synthesis gas so that it meets the requirements of the Fischer-Tropsch synthesis reaction, and then produce the corresponding liquid hydrocarbons and paraffin products. Variants of devices for Fischer-Tropsch synthesis are claimed.

EFFECT: reducing the complexity and cost of the process of converting water vapor used in the process, reducing carbon dioxide emissions.
