Method for carrying out slurry bed reaction

Abstract

The invention relates to a method for carrying out a slurry bed reaction. The method comprises that: a) a gaseous component is introduced into a slurry bed reactor to make the gaseous component rise, concurrently a slurry is driven to rise along with the rising gaseous component, and the gaseous component reacts in the slurry; b) the gaseous product of the reaction and the unreacted gaseous component rise and leave a slurry bed layer (3), at least a part of the slurry enters a diversion pipe (17) from the upper portion opening of the diversion pipe (17), flows downward along the diversion pipe (17), outflows from the lower portion outlet of the diversion pipe (17), and enters an annular space, and at least a spraying nozzle sprays the gas, the liquid or the slurry; and (c) the steps (a) and (b) are repeatedly performed. With the method, the mass transfer and the heat transfer in the slurry bed reaction system can be promoted.

[0001] The invention belongs to the field of chemical industry and relates to a method for performing slurry bed reaction. Background technique

[0002] In the organic chemical synthesis process, the gas-liquid-solid three-phase reaction system containing gaseous, liquid and solid reaction materials is a very important system. For example, the slurry bed reactor for Fischer-Tropsch synthesis is an industrial application three-phase reactor. The Fischer-Tropsch synthesis process refers to the synthesis gas (CO+H 2 ) into hydrocarbons and small amounts of organic oxygenates, a chemical conversion process characterized by a strong exotherm. Initially, people tried to use fixed bed and fluidized bed reactors for Fischer-Tropsch reaction operation, but the heat transfer efficiency of these reactors is not ideal, which will bring great difficulties to the reaction control. For this reason, a novel slurry bed reactor has been developed. The characteristic of th...
