Conversion of synthesis gas to hydrocarbons in the presence of a liquid phase

摘要

The synthesis of linear and saturated 5C<+> hydrocarbons from a gaseous phase containing the synthesis gas consists of subjecting the liquid and the gas phases in a reaction zone where the hydrocarbons are formed by Fisher-Tropsch reaction. The reaction zone is equipped with means of inserting the gaseous and the liquid phases, means of drawing off the hydrocarbons formed and means of mixing. The conversion of synthesis gas into hydrocarbons is carried out at a total pressure 0.1-15 MPa, temperature 150-350 degrees C, space velocity ranging between 100-2000 volumes of synthesis gas per volume of catalyst and per hour and molar ratio of H2/CO in the synthesis gas between 0.5-5.
