Gas-liquid-solid three-phase suspension bed reactor for fischer-tropsch synthesis and its applications

A gas-liquid-solid three phase suspension bed reactor for Fischer-Tropsch synthesis, which is used for F-T synthesis reaction of synthesis gas (CO+H2) to synthesize F-T fuel by low temperature slurry bed process or high temperature slurry bed process in the presence of catalyst;

• the reactor comprising:
• a reactor main body having a vertical cylindrical body with a height of from about 25 meters to about 45 meters;
• a direct introduction type or a clapboard distribution type gas distributor located at a bottom of the reactor main body;
• a lower primary heat exchanger immersed in a three-phase reaction region and located in a lower portion of a reaction zone bounded by the reactor main body;
• an upper primary heat exchanger having a first portion immersed in the three-phase reaction region and a remaining portion extending above the level of the three-phase reaction region into a gas separation zone above the three-phase reaction region, the upper primary heat exchanger located in an upper portion of the reaction zone bounded by the reactor main body;
• an ancillary heat exchanger located above a the gas separation zone;
• a plurality of sets of solid catalyst-liquid heavy products separators disposed axially about at least a portion of the reactor main body;
• a plurality of groups of vertical flow guidance pipes, each group of the plurality of groups including at least one vertical flow guidance pipe to circulate a respective vertical portion of the three-phase reaction region and positioned axially about an inside of the reactor main body;
• a mist separation device located proximate a top of the reactor main body;
• and
• at least two supplemental systems, including an ancillary system proximate a bottom of the reactor main body to handle deposited slurry, and a pre-condensate and mist separation system located in a top of a reactor outlet.
