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.
