A start-up method for a hydrocarbon synthesis reaction apparatus, comprising: an initial slurry-loading step in which the slurry is loaded into the reactor at the initial stage of the Fischer-Tropsch synthesis reaction at a lower loading rate than that applied to the reactor in a steady-state operation; and a CO conversion ratio-increasing step in which the liquid level of the slurry in the reactor is raised by adding to the slurry the hydrocarbons synthesized at the early stage of the Fischer-Tropsch synthesis reaction so that the CO conversion ratio is increased in proportion to a rise in the liquid level of the slurry in the reactor.

A hydrocarbon synthesis reaction apparatus includes a reactor that brings a synthesis gas into contact with a slurry having a solid catalyst suspended in liquid hydrocarbons to synthesize hydrocarbons by the Fischer-Tropsch synthesis reaction; a cylindrical inner tube having a lower end arranged within the reactor at a predetermined distance from the bottom of the reactor; and a sparger that is arranged on an inner lower side of the inner tube and blows the synthesis gas toward the inside of the inner tube. A Fischer-Tropsch synthesis reaction region, to which the slurry including bubbles flows out from the inside of the inner tube through an upper end of the inner tube, is formed in a space between a virtual extension portion of the upper end of the inner tube and an inner surface of the reactor, in a state where the slurry is held within the reactor until the upper end of the inner tube is lower than the liquid level of the slurry.

A start-up method of a bubble column slurry bed reactor for producing hydrocarbons includes: a first step that fills into a reactor a slurry in which a Fischer-Tropsch synthesis reaction catalyst particles are suspended in a slurry preparation oil with a 5% distillation point of 120 to 270C, a 95% distillation point of 330 to 650C, and a sulfur component and an aromatic component of 1 mass ppm or less, and a second step that, in a state where synthesis gas that is primarily hydrogen and carbon monoxide is introduced into the slurry filled into the reactor, raises the temperature of the reactor and starts the Fischer-Tropsch synthesis reaction. As the slurry preparation oil, one containing predetermined components in preset amounts is used. In the first step, the slurry is filled into the reactor in an amount in which airborne droplets do not flow out.
