Abstract: A method of producing normally solid, normally liquid and optionally normally gaseous hydrocarbons involves contacting a gas mixture comprising hydrogen and carbon monoxide with a catalyst under elevated temperature and pressure, to convert at least part of the hydrogen and carbon monoxide into hydrocarbons. An effluent is withdrawn from the reactor and subjected to a separation step to form at least a heavy fraction and a light fraction. The heavy fraction comprises normally solid hydrocarbons, while the light fraction comprises unconverted syngas and normally liquid and optionally normally gaseous hydrocarbons.The light fraction is sent to a light ends stripper operating at a temperature of maximally 200° C. to obtain a hydrocarbons fraction comprising normally liquid hydrocarbons. The heavy fraction is subjected to flash evaporation or steam stripping to obtain a hydrocarbon stream of normally solid hydrocarbons (comprising mainly C10+ hydrocarbons).
