Abstract

A process for producing a hydrocarbon oil is provided in which fine catalyst particles derived from a catalyst for FT synthesis reaction can be inhibited from coming into the reaction system of an upgrading step for the FT synthetic oil. This process for hydrocarbon oil production includes: conducting a Fischer-Tropsch synthesis reaction using a slurry-bed reactor (C2) which contains a liquid-hydrocarbon slurry containing a suspended catalyst to thereby obtain a hydrocarbon oil that contains fine catalyst particles derived from the catalyst; fractionating the hydrocarbon oil into a distillate oil and a bottom oil containing the fine catalyst particles by means of a rectifier (C4); transferring at least some of the bottom oil to a storage tank (T2); sedimenting the fine catalyst particles on the bottom of the storage tank (T2) and collecting the sedimented particles; transferring the remainder of the bottom oil from the rectifier (C4) to a hydrocracker (C6) and/or transferring the supernatant of the bottom oil from which the fine catalyst particles have been collected by means of the storage tank (T2), from the storage tank (T2) to the hydrocracker (C6); and hydrocracking the remainder of the bottom oil and/or the supernatant of the bottom oil using the hydrocracker (C6).
