Abstract

A catalyst filling apparatus is for a bubble column slurry bed reactor for the FT synthesis reaction. The apparatus includes: a slurry preparation tank installed adjacent to the reactor and configured to prepare a slurry S from a FT synthesis reaction catalyst and a slurry preparation oil; an upper part communication line configured to direct the slurry from the reactor to the slurry preparation tank; a lower part communication line configured to direct the slurry in the slurry preparation tank to the reactor; and a pressure equalizing line configured to communicate the reactor with the slurry preparation tank. The upper part communication line is downwardly inclined from the reactor toward the slurry preparation tank, and the lower part communication line is upwardly inclined from the reactor toward the slurry preparation tank. An inert gas introduction device is provided on the slurry preparation tank.

First claim

The invention claimed is:

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.

2. A catalyst filling method of a bubble column slurry bed reactor for filling a Fischer-Tropsch synthesis reaction catalyst into a bubble column slurry bed reactor for a Fischer-Tropsch synthesis reaction using the catalyst filling apparatus of a bubble column slurry bed reactor according to claim 1 , the catalyst filling method comprising:
a slurry preparation step of stirring a slurry preparation oil in the slurry preparation tank on heating to make a prepared slurry in which the catalyst is suspended within the slurry preparation oil;
a purging step in which an inert gas is introduced to the slurry preparation tank by the inert gas introducing device to replace oxygen within the prepared slurry and the slurry preparation tank with inert gas;
a pressure equalization step after the purging step, in which the pressure equalizing line on-off valve is opened to make the pressures inside the reactor and the slurry preparation tank the same;
a slurry circulation step after the pressure equalization step, in which the slurry in the slurry preparation tank is introduced to the reactor while introducing the slurry in the reactor to the slurry preparation tank by opening the upper part communication line on-off valve and the lower part communication line on-off valve, and
a slurry circulation completion step following the slurry circulation step, in which the upper part communication line on-off valve and closing the pressure equalizing line on-off valve are closed, subsequently the inert gas is introduced to the slurry preparation tank by the inert gas introducing device to pressure transfer the slurry in the slurry preparation tank via the lower part communication line to the reactor, and thereafter the lower part communication line on-off valve is closed.
