Catalyst filling device for bubble column type slurry bed reactor and catalyst filling method for bubble column type slurry bed reactor

Abstract

The present invention relates to a catalyst packing device installed on a bubble column type slurry bed reactor for FT synthesis reaction. It includes: a slurry preparation tank for preparing slurry S from a FT synthesis reaction catalyst and slurry preparation oil installed adjacent to the reactor, an upper communication pipe for guiding the slurry from the reactor to the slurry preparation tank, and The slurry is guided from the slurry preparation tank to the lower connecting pipe in the reactor, and the pressure equalizing pipe that communicates the inside of the reactor with the inside of the slurry preparation tank. The upper communication pipe slopes downward from the reactor toward the slurry preparation tank, and the lower communication pipe slopes upward from the reactor toward the slurry preparation tank. An inert gas introduction mechanism for introducing an inert gas is provided on the slurry preparation tank.

Description

technical field [0001] The invention relates to a catalyst filling device for a bubble column type slurry bed reactor and a catalyst filling method for the bubble column type slurry bed reactor. [0002] this application claims priority to the patent application 2012-074758 for which it applied to Japan on March 28, 2012, The content is used here. Background technique [0003] In recent years, from the viewpoint of reducing the environmental load, environmentally friendly green liquid fuels with low sulfur components and aromatic hydrocarbon contents have been sought. From this point of view, as a technology capable of producing fuel oil bases free of sulfur components, aromatic hydrocarbons, and rich in aliphatic hydrocarbons, especially kerosene and light oil bases, the use of carbon monoxide gas (CO) has been studied. and hydrogen (H 2 ) is a method of Fischer-Tropsch synthesis reaction (hereinafter referred to as "FT synthesis reaction") of raw material gas (for exampl...

Problems solved by technology

Therefore, the inventors paid attention to the following problem: Even if the slurry prepared by the catalyst is put into the reactor while taking out the catalyst in the reactor, the catalyst will be precipitated and separated from the slurry during the operation, so that the piping Or blockage will occur near the valve
