1. A synthesis reaction system for hydrocarbon compound, comprising:

  • a reactor configured 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;

    a separator configured to separate the hydrocarbon compound from the slurry;

    a plurality of filtering devices configured to filter the hydrocarbon compound extracted from the separator to trap powdered catalyst particles, and arranged in parallel, wherein each filtering device comprises a filtering vessel and one or more filters disposed inside the filtering vessel;

    a supply pipeline for supplying the hydrocarbon compound extracted from the separator to the plurality of filtering devices, the supply pipeline comprising a plurality of branch portions, each connecting the separator and one of the filtering devices, wherein each branch portion of the supply pipeline is provided with a valve which opens and closes the branch portion to individually switch supply of the hydrocarbon compound to each filtering device;

    a discharge pipeline connected to the plurality of filtering devices for discharging the hydrocarbon compound filtered by the one or more filters from the filtering vessel of each filtering device to the outside of the filtering vessel of each filtering device, the discharge pipeline comprising a plurality of branch portions, each connected to one of the filtering devices;

    a cleaning device comprising a cleaning fluid supply section and configured to remove from the one or more filters of the filtering vessel of each filtering device the powdered catalyst particles adhered to the one or more filters by supplying an inert gas from the cleaning fluid supply section to the filtering vessel through the one or more filters;

    a gas supply pipeline connected to the discharge pipeline for supplying the inert gas from the cleaning device, the gas supply pipeline comprising a plurality of branch portions, each of which is connected to a branch portion of the discharge pipeline for supplying the inert gas into the filtering vessel of each filtering device through the one or more filters;

    a gas discharge pipeline connected to an upper portion of the filtering vessel of each filtering device for discharging the inert gas supplied to the filtering vessel through the one or more filters from the filtering vessel, wherein the upper portion of the filtering vessel of each filtering device to which the gas discharge pipeline is connected is higher than one or more filters inside the filtering vessel; and

    a particle discharge pipeline connected to a lower end of the filtering vessel of each filtering device for discharging the powdered catalyst particles removed from the one or more filters from the filtering vessel,wherein the synthesis reaction system is configured such that while the hydrocarbon compound is filtered in one filtering device by opening the supply pipeline by the valve so that the one filtering device filters the hydrocarbon compound, the hydrocarbon compound is not filtered in at least one other filtering device by closing the supply pipeline by the valve and the one or more filters in at least one other filtering device are cleaned.
