PURPOSE:To heat up a carbon monoxide converter to a required temperature, by supplying a Co-Mo-Al2O3 catalyst layer with the oxygen-containing gas to be processed, and heating the catalyst layer by the heat of reaction of hydrogen with oxygen contained in the feed gas. CONSTITUTION:When the gas production is interrupted, the temperature of the conversion catalyst layer in the carbon monoxide converter decreases. At the restarting of the carbon monoxide conversion process, the feed gas added preliminary with a specific amount of oxygen is fed to the carbon monoxide converter, and the catalyst layer is heated by the heat of water-producing reaction of hydrogen with oxygen contained in the gas on the catalyst. The oxygen-content of the feed gas is generally about 0.1-5.0vol% preferably about 0.5- 3.0vol%. The oxygen source may be pure oxygen or air. The time necessary to heat up the catalyst layer to the stationary state can be shortened to about 1/3 compared with the conventional method. |
