CARBON MONOXIDE REMOVER, AND FUELREFORMING SYSTEM HAVING THE CARBON MONOXIDE REMOVE

摘要

A carbon monoxide removal method capable of removing carbon monoxide stably for long period when a fuel reforming system is operated, comprising the step of adding oxidizer to a reaction gas including hydrogen and carbon monoxide to react on a carbon monoxide removal catalyst so as to remove the carbon monoxide under the conditions that (1) the temperature of the reaction gas is held at 100 °C or below, (2) the temperature of a catalyst layer is held at 130 to 180 °C, and (3) a gas flow passage is formed of a non-ferrous material or (4) an iron particle arresting means is installed on the upstream side of a catalyst part.
