Abstract

The invention discloses a novel slurry bed ft synthesis reactor, which comprises a reactor inlet, a reactor outlet, a reaction segment at the lower part of a reactor and a gas-liquid expansion section at the upper part of the reactor, the gas-liquid expansion section at the upper part of the reactor is a taper contraction section, the bottom of the taper contraction section is connected to a reaction segment, the outlet of the reactor is provided at the top. The reactor has high utilization rate of the inner space in the device and good demisting effect, and can enhance the conversion rate of carbon monoxide and stability of a ft synthesis catalyst, and can reduce the methane selectivity.

Description

technical field [0001] The invention relates to a slurry bed Fischer-Tropsch synthesis reactor. Background technique [0002] Fischer-Tropsch synthesis refers to synthesis gas (CO+H 2 ) on the catalyst to catalyze the reaction of synthesizing hydrocarbon liquid fuel. With the increasing depletion of petroleum resources, the preparation of liquid fuels by Fischer-Tropsch synthesis has attracted more and more attention from all over the world. [0003] The reactors used for F-T synthesis include fixed bed, circulating fluidized bed, fixed fluidized bed and slurry bed. The fixed bed reactor has the disadvantages of hot spots, clogging and low production capacity, the fluidization process of the circulating fluidized bed is difficult to control, the catalyst utilization rate is low and the wear is serious, and the production capacity is still low. Fixed fluidized bed is an improved form of circulating fluidized bed. It not only has a simple structure and is easy to operate,...
