Slurry bed reactor and Fischer-Tropsch synthesis method

Abstract

The invention relates to the field of hydrocarbon synthesis and specifically provides a slurry bed reactor and a Fischer-Tropsch synthesis method. The reactor comprises a reactor inlet section, a gasdistributor, a reaction section and a gas-liquid-solid separation section arranged from bottom to top; a solid-liquid separator communicating with a liquid product outlet of the reactor is arranged below the middle inside the reaction section; a plurality of degassing, liquid collecting and diversion parts are arranged above the middle inside the reaction section; and each of the degassing, liquidcollecting and diversion parts comprises a funnel-shaped open section and a diversion pipe section communicating from top to bottom. Compared with the prior art, the reactor provided by the inventionis capable of obviously improving the performances of a catalyst when being applied to a gas-liquid-solid three-phase reaction, and the wear and consumption of the catalyst are obviously reduced.

Description

technical field [0001] The invention relates to the field of hydrocarbon synthesis, in particular to a slurry bed reactor and a Fischer-Tropsch synthesis method. Background technique [0002] With the continuous rise of oil prices in recent years, people pay more and more attention to the development of technologies to produce alternative oil products. Syngas is produced through coal, natural gas or other substances, and then according to the requirements of the Fischer-Tropsch synthesis catalyst for synthesis gas, through water-gas shift and synthesis The gas purification process processes the syngas, and uses the treated syngas as a raw material to produce hydrocarbons through Fischer-Tropsch synthesis, and at the same time produces oxygenated compounds, which are then processed by mature petroleum processing technology to produce high-quality, environmentally friendly oil. Taste. The development of Fischer-Tropsch synthesis technology is of great significance to the deve...

AI Technical Summary

Problems solved by technology

The Fischer-Tropsch synthesis slurry bed reactor requires the particle size of the catalyst to be between 20-100 microns, otherwise the catalyst and the product cannot form a slurry phase. and gas phase product) separation problem

[0007] Especially with the progress of the reaction, the wear of the catalyst is getting worse, the average particle diameter is getting smaller and smaller, the gas-solid separation is getting more and more difficult, and the solid entrainment is serious, which affects the subsequent operation
