METHOD FOR STOPPING OPERATION OF REACTION CONTAINER

摘要

This method for stopping the operation of a reaction container involves a stopping step in which the supply of synthesis gas containing carbon monoxide gas and hydrogen gas into a reaction container is stopped, a slurry discharging step in which a slurry is discharged from the reaction container, a steam supplying step in which steam having a temperature equal to or higher than the decomposition temperature of metal carbonyl is supplied into the reaction container and the gas in the reaction container is discharged, and a carbon monoxide gas detecting step in which the amount of carbon monoxide in the gas discharged from the reaction container is detected. In the steam supplying step, the supply of steam is stopped when the detected amount of carbon monoxide gas continuously drops and becomes equal to or less than a predetermined reference value.
