Claim Text:
1. A catalyst filling apparatus provided in a bubble column slurry bed reactor for a Fischer-Tropsch synthesis reaction, the catalyst filling apparatus comprising: a slurry preparation tank installed adjacent to the reactor, and configured to prepare a slurry from a Fischer-Tropsch synthesis reaction catalyst and a slurry preparation oil; an upper part communication line configured to direct the slurry in the reactor to the slurry preparation tank; an upper part communication line on-off valve provided on the upper part communication line; a lower part communication line configured to direct the slurry in the slurry preparation tank to the reactor; a lower part communication line on-off valve provided on the lower part communication line; a pressure equalizing line configured to communicate an upper part void part in the reactor with an upper part void part in the slurry preparation tank and to make the pressures inside the reactor and the slurry preparation tank the same; and a pressure equalizing line on-off valve provided on the pressure equalizing line, wherein the upper part communication line is connected to the reactor in a position that, with respect to the slurry liquid in the reactor during stationary operation, is equal to or higher than a half level of the slurry liquid in a height direction of the reactor and is lower than a liquid surface of the slurry, the upper part communication line is downwardly inclined from the reactor toward the slurry preparation tank, and is connected to the slurry preparation tank in a position that is equal to or higher than a half level of the slurry preparation tank in a height direction of the slurry preparation tank, the lower part communication line is connected to the reactor in a position that, with respect to the slurry liquid in the reactor during stationary operation, is lower than the half level of the slurry liquid in the height direction of the reactor, the lower part communication line is upwardly inclined from the reactor toward the slurry preparation tank, and is connected to the slurry preparation tank in a position that is the lower end section of the slurry preparation tank, and the slurry preparation tank is provided with a catalyst charging device configured to charge a Fischer-Tropsch synthesis reaction catalyst, an inert gas introducing device configured to introduce an inert gas to the slurry preparation tank, a slurry preparation oil supplying device configured to supply a slurry preparation oil, a slurry heating device that heats the slurry in the slurry preparation tank, and a slurry stirring device configured to stir the slurry to mix the slurry.
