MOTOR FUEL COMPONENTS PRODUCTION BY FISCHER-TROPSCH SYNTHESIS

The Fischer – Tropsch synthesis makes it possible to obtain various types of products depending on the catalyst used (linear long-chain alkanes, components of motor fuels, gases, heavy products). The article provides an analysis of the development of industrial Fischer – Tropsch synthesis technologies. The authors investigated the Fischer – Tropsch process on a model mixture consisting of carbon monoxide and hydrogen on a bifunctional zeolite-free catalyst consisting of a carrier – montmorillonite treated with sulfuric acid, intercalated with a polyvalent zirconium cation, promoted with a solution of cobalt nitrate and organometallosiloxane (ruthenium carbonophenylsiloxane), which allows to obtain components of motor fuels in one stage. The studies were conducted at temperature 210 °C (previously conducted experiments indicate that at this temperature the maximum yield of iso-paraffins is achieved) and pressures 4, 6, 8 MPa. It has been found that the highest yield of iso-paraffins is achieved at pressure 6 MPa. The analysis of the obtained gasoline fraction for compliance with State Standard 32513-2013 for motor gasoline has been carried out. It has been established that the product complies with environmental class K5 and can be used as a component of commercial motor fuel.
