Slurry bed reaction equipment

Abstract

The invention discloses slurry bed reaction equipment which comprises a slurry bed reactor and an extraction device, wherein the slurry bed reactor comprises a slurry outlet which is arranged at the bottom and a return slurry inlet which is located at the upper part; and the extraction device is connected between the slurry outlet and the return slurry inlet and used for extracting the slurry at the bottom of the slurry bed reactor and lifting back to the upper part of the slurry bed reactor. In the invention, the slurry outlet is arranged at the bottom of the slurry bed reactor, the return slurry inlet is arranged at the upper part of the slurry bed reactor, and the extraction device is utilized for extracting the slurry in the slurry bed reactor through the slurry outlet, returning the slurry to the upper part of the bed slurry reactor through the return slurry inlet and then extracting the slurry from the bottom of the slurry bed reactor, so that the problem that catalysts at the bottom of a slurry bed precipitate is solved; and the extracted slurry is returned to the upper part of the slurry bed reactor, so that the back mixing of the catalysts is strengthened and the axial uniform distribution of the catalysts is promoted.

Description

technical field [0001] The invention relates to the field of Fischer-Tropsch synthesis, in particular to a slurry bed reaction equipment suitable for Fischer-Tropsch synthesis. Background technique [0002] Fischer-Tropsch synthesis reactor is the core reactor of indirect liquefaction technology, and it is a slurry bed reactor widely used at home and abroad that can produce more hydrocarbon products. Fischer-Tropsch synthesis slurry bed has the advantages of uniform and easy control of temperature, wide operating range of gas velocity, high alpha value of product, and online replacement of catalyst. The dispersion of the gas phase in the existing slurry bed indirectly affects the uniform dispersion of the liquid phase and the catalyst particle phase. In the past, the research on the slurry bed mostly hoped that the gas distribution in the radial direction would be more uniform by using an optimized inlet distributor. The Fischer-Tropsch synthesis reaction is a reaction of v...
