METHOD OF OPERATING RUTHENIUM-CATALYST REACTOR

摘要

A catalytic reactor and a method of using the same are provided that can be stably used even when an apparent catalyst volume relative to a reaction container is reduced. The catalytic reactor includes: the reaction container filled with a catalyst; and an introduction part for introducing a material fluid to the reaction container. The reaction container is filled with the catalyst having ruthenium supported thereon, and supplied with a mixed gas as material fluid, to produce synthetic gas containing hydrogen and carbon monoxide, in the presence of the ruthenium catalyst. The introduction part is connected to the reaction container in a horizontal direction or a direction inclined downward from above a horizontal plane, and a filling height level of the catalyst filled in the reaction container is adjusted above a height level at which the material fluid is fed from the introduction part to reaction container. The method includes a step of monitoring a molar ratio of carbon and oxygen contained in the material fluid, and stopping the supply of an oxygen-containing gas to the reaction container before the molar ratio becomes excessively low.
