Method of operating ruthenium catalyst reactor

摘要

A catalytic reactor including: a reaction container filled with a catalyst having ruthenium; and an introduction part for introducing a material fluid to the reaction container. The reaction container is supplied with a mixed gas as material fluid to produce synthetic gas containing hydrogen and carbon monoxide in the presence of the 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 height of the catalyst filled in the reaction container is adjusted above a height at which the material fluid is fed from the introduction part to the reaction container. Also, a method of using the catalytic reactor including 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.

1. A method of operating a ruthenium catalyst reactor comprising steps of: supplying hydrocarbon gas, steam and oxygen-containing gas to a reaction container having a ruthenium catalyst therein; allowing a partial oxidation reaction to proceed in the presence of the ruthenium catalyst; and producing synthetic gas containing hydrogen and carbon monoxide,
the method further comprising steps of: monitoring a molar ratio (C/O2) of carbon contained in the hydrocarbon gas and oxygen contained in the oxygen-containing gas which are supplied to the reaction container, and stopping the supply of the oxygen-containing gas to the reaction container before the molar ratio (C/O2) is reduced below a critical molar ratio in terms of molar ratio (C/O2) at which scattering of ruthenium in the ruthenium catalyst is generated, a different molar ratio (C/O2) being adopted as the critical molar ratio in accordance with a type of the hydrocarbon gas, with the critical molar ratio (C/O2) being set to 1 or less.
