Claim:
A bubble column-type slurry bed reaction system in a Fischer-Tropsch synthesis reaction system for producing liquid hydrocarbon products by contacting a synthesis gas composed of hydrogen and carbon monoxide with catalyst particles, the slurry bed reaction system comprising: a gas distributor arrangement configured to supply the synthesis gas continuously from a bottom of a reactor so that the synthesis gas contacts the catalyst particles that are suspended to form the liquid hydrocarbon products, gaseous hydrocarbon products, and water in a Fischer-Tropsch synthesis reaction procedure; a downwardly inclined transfer pipe arrangement configured to transfer the suspended liquid hydrocarbons formed in the Fischer-Tropsch synthesis reaction procedure and catalyst particles from the reactor to a lower portion of a separation vessel to separate the catalyst particles and the liquid hydrocarbon products; and a connecting pipe arrangement which is installed above the downwardly inclined transfer pipe arrangement and configured to supply the gaseous hydrocarbon products formed in the Fischer-Tropsch synthesis reaction procedure to an upper portion of the separation vessel, wherein: the slurry bed reaction system is configured such that the liquid hydrocarbon products are derived from the separation vessel, a slurry in which the catalyst particles are concentrated is derived from a bottom of the separation vessel and circulated to the bottom of the reactor, and is driven by a driving force of the synthesis gas introduced from the bottom of the reactor and which rises through the reactor without using an external drive power source for a circulation, and the formed liquid hydrocarbon products, gaseous hydrocarbon products and water are separated and derived without using the external drive power source for the separation, and the separation vessel includes a slurry circulation pathway that circulates a catalyst particle-concentrated slurry to the reactor and a liquid rise velocity inside the separation vessel is controlled to be 0.4 times or less of a sedimentation velocity of catalyst particles having a particle diameter of 20 Î¼m by a catalyst-concentrated slurry derivation rate control valve installed in the slurry circulation pathway between the separation vessel and the reactor, a derivation rate control valve for the liquid hydrocarbon products derived from the separation vessel, and a differential pressure control valve in an upper gas phase space between the separation vessel and the reactor.
