PURPOSE:To provide a CO converter having a long service life and high performance by measuring the temp. of a gas on the outlet side of a vessel packed with a CO conversion catalyst and controlling the amt. of cooling water based on the measurement signal to hold the outlet gas at a specified temp. CONSTITUTION:A vessel 2 packed with a CO conversion catalyst 1, an inlet cooler 3, an intermediate cooler 4, etc., are integrated to constitute a CO converter. A gaseous reactant contg. CO and steam is supplied to the converter from an inlet 5 to cause an exothermic reaction in the presence of the catalyst and converted into CO2 and hydrogen, and the converted gas is discharged from an outlet 6. The outlet gas temp. is measured by a thermometer 11 set at the outlet 6, the control valve 10 of a cooling water pipeline 9 is actuated by a controller 12 based on the measurement signal to adjust the amt. of cooling water to be supplied to the cooler 3, hence the outlet gas is held at a specified temp., and the reaction is carried out. Consequently, the outlet gas is always held at a specified temp. irrespective of the amt. of the gaseous reactant, and the composition of the outlet gas is kept constant. |
