In the hydrocarbon-producing apparatus, a vapor-liquid separation tank of a second vapor-liquid separation unit is provided with a filling material layer. A vapor-liquid separation tank of the first vapor-liquid separation unit has a first return line. The vapor-liquid separation tank of the second vapor-liquid separation unit has a second return line. A light component of light oil discharged from a bottom of the vapor-liquid separation tank is returned to a portion between a top side above a return-location from the second return line within the vapor-liquid separation tank of the second vapor-liquid separation unit, and a line directly connected with a cooler installed on the first vapor-liquid separation unit through the first return line. A heavy component of light oil discharged from a bottom of the vapor-liquid separation tank of the second vapor-liquid separation unit is returned to the filling material layer through the second return line.

Hydrocarbon-producing apparatus and hydrocarbon-producing method

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.
