GENERAL INFORMATION ABOUT THE PROCESS OF SYNTHESIZING HYDROCARBONS FROM CO2 AND H2

Abstract

The process of catalytic synthesis of hydrocarbons from syngas to high molecular weight synthetic pentane to nonadecane is a strongly exothermic reaction. Its thermal effect is equal to 41 kcal/mol, activation energy is equal to 24 kcal/mol [1]. Thermodynamic calculations [1 3] show that at pressures of 1–100 atm and temperatures of 20–700°C, the formation of saturated hydrocarbons, especially methane, is likely. At 1 atm, the upper temperature limit for the formation of hydrocarbons ranging from high molecular weight synthetic pentane to nonadecane is 400–500°C.
