Abstract
A method for producing hydrocarbons includes: a synthesis step of synthesizing hydrocarbons by the Fischer-Tropsch synthesis reaction using a slurry bubble column reactor having a slurry containing catalyst particles and liquid hydrocarbons retained inside the reactor, and having a gas phase portion located above the slurry; a discharging step of passing the slurry through a filter positioned inside and/or outside the reactor, thereby separating and discharging the heavy liquid hydrocarbons; a backwash step of flushing liquid hydrocarbons through the filter in the opposite direction to the flow of the slurry, thereby returning the catalyst particles to the reactor; and a cooling and gas-liquid separation step of cooling the hydrocarbons discharged from the gas phase portion, and then separating and collecting the condensed light liquid hydrocarbons. The liquid hydrocarbons flushed through the filter in the backwash step include the light liquid hydrocarbons obtained in the cooling and gas-liquid separation step.
