    Abstract: PROBLEM TO BE SOLVED: To provide a method for producing hydrocarbon, reducing the amount of liquid hydrocarbon that goes back and forth through a filter and repeats flowing through it to reduce the load of the filter.SOLUTION: This method for producing hydrocarbon includes: a synthesis step for using a bubble column-type slurry bed reactor to synthesize hydrocarbon by a Fischer-Tropsch synthesis reaction, the reactor having a gas phase part at the top and holding a slurry including catalyst particles and liquid hydrocarbon; an extraction step for causing the slurry to flow through the filter disposed on the interior and/or exterior of the reactor to separate out the heavy liquid hydrocarbon, and extracting the heavy liquid hydrocarbon; a backwashing step for causing the liquid hydrocarbon to flow through the filter in a direction inverse to the direction of flow of the slurry and returning the catalyst particles to the reactor; and a cooling and gas-liquid separation step for cooling the hydrocarbon expelled from the gas phase part and separating out and collecting the condensed light liquid hydrocarbon. The liquid hydrocarbon made to flow in the backwashing step includes the light liquid hydrocarbon obtained in the cooling and gas-liquid separation step.
