Patent ID: 8758692

Claim:
A synthesis reaction system used to synthesize a hydrocarbon compound by a chemical reaction of a synthesis gas including hydrogen and carbon monoxide as main components, and a slurry having solid catalyst particles suspended in liquid and which extracts the hydrocarbon compound from the slurry, the synthesis reaction system comprising: a reactor main body which accommodates the slurry; a separator which separates the hydrocarbon compound included in the slurry from the slurry; a first flow passage which allows the slurry including the hydrocarbon compound to flow to the separator from the reactor main body; a second flow passage whose inlet port is connected to a lower section of the bottom of the separator, and which allows the slurry to flow to the reactor main body from the separator; dividing valves provided to the first and second passages and which are driven so as to close the first and second passages when a normal operation of the system is stopped, a first fluid supply nozzle which is connected to the lower section of the bottom of the separator, and which is configured to upwardly-supply a fluid into the separator through the inlet port of the second flow passage when the normal operation of the system is stopped; and a second fluid supply nozzle which is connected to a middle portion of the second flow passage, and which is configured to supply the fluid into the second flow passage when the normal operation of the system is stopped.
