METHOD OF PRODUCING CERESIN Russian patent published in 2024 - IPC C07C1/04 B01J21/02 B01J23/75 

FIELD: chemistry.

SUBSTANCE: invention relates to chemical industry, petrochemistry and gas chemistry, and can be used for the process of producing synthetic ceresin from carbon monoxide and hydrogen by the Fischer-Tropsch method. Method of producing C₁₉₊ hydrocarbons with high content of C₃₅₊ ceresin from CO and H₂ by the Fischer-Tropsch method involves contacting a gas mixture with an effective amount of a catalyst and is characterized by that the method is carried out at pressure of 1.8–2.2 MPa, a contact temperature of 210–225°C, molar ratio of carbon monoxide and hydrogen of 1.8:2.2 and volumetric gas feed rate of 500–1,200 h^-1 on a catalyst of composition, wt.%: cobalt – 20.6–22.2, aluminium additive – 0.8–1.2, silica gel carrier – the rest.

EFFECT: efficient and selective method of producing target C₁₉₊ hydrocarbons enriched with ceresin fraction.
