Abstract

Hydrocarbon oil obtained by Fischer-Tropsch synthesis reaction using a slurry bed reactor holding a slurry of a liquid hydrocarbon in which a catalyst is suspended; the hydrocarbon oil is fractionated into a distilled oil and a column bottom oil containing the catalyst fine powder by a rectifying column; at least part of the column bottom oil is transferred to a storage tank, and the catalyst fine powder is sedimented to the bottom of the storage tank to capture the catalyst fine powder; a residue of the column bottom oil is transferred from the rectifying column to a hydrocracker, and/or the supernatant of the column bottom oil from which the catalyst fine powder is captured by the storage tank is transferred from the storage tank to the hydrocracker; and using the hydrocracker, the residue of the column bottom oil and/or the supernatant of the column bottom oil is hydrocracked.

Claims

1. A method for producing a hydrocarbon oil, comprising:

a step of obtaining a hydrocarbon oil containing a catalyst fine powder derived from a catalyst by a Fischer-Tropsch synthesis reaction using a slurry bed reactor holding a slurry containing a liquid hydrocarbon and the catalyst suspended in the liquid hydrocarbon within the slurry bed reactor;

a step of fractionating the hydrocarbon oil into at least one distilled oil and a column bottom oil containing the catalyst fine powder using a rectifying column;

a step of transferring at least part of the column bottom oil to a storage tank, and sedimenting the catalyst fine powder to a bottom of the storage tank to capture the catalyst fine powder; and

a step of transferring a residue of the column bottom oil from the rectifying column to a hydrocracker, and/or transferring a supernatant of the column bottom oil in which the catalyst fine powder is captured in the storage tank from the storage tank to the hydrocracker to hydrocrack the residue of the column bottom oil and/or the supernatant of the column bottom oil using the hydrocracker.

2. The method for producing a hydrocarbon oil according to claim 1, wherein the storage tank comprises a structure for suppressing movement of the catalyst fine powder sedimented to the bottom of the storage tank in the bottom of the storage tank.
