Catalyst packing device of bubble tower-type slurry bed reactor and catalyst packing method of bubble tower-type slurry bed reactor

Abstract

Provided is a catalyst packing device disposed at a bubble tower-type slurry bed reactor for FT synthesis. The packing device comprises, disposed adjacent to the reactor, a slurry preparation cell for preparing a slurry S from an FT synthesis catalyst and a slurry preparation oil, a top communicating pipe for guiding slurry from the reactor to the slurry preparation cell and a bottom communicating pipe for guiding slurry from the slurry preparation cell to the reactor, and an equalizing pipe for communication between the inside of the reactor and the inside of the slurry preparation cell. The top communicating pipe is inclined down from the reactor toward the slurry preparation cell and the bottom communicating pipe is inclined up from the reactor toward the slurry preparation cell. Inert gas introduction means for introducing inert gas are disposed at the slurry preparation cell.

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
