Title:
HYDROGEN PRODUCING APPARATUS
Document Type and Number:
Japanese Patent JP2003277010
Kind Code:
A
Abstract:

To solve the problem that the carbon monoxide removing capacity of a CO oxidizing part is affected by the mixed state of oxygen with carbon monoxide in the reformed gas to be fed to the CO oxidizing part or the distributed state of a stream of the reformed gas.

This hydrogen producing apparatus is provided with a conversion part 1 having a conversion catalyst for decreasing carbon monoxide contained in the reformed gas, a mixing part 2 for mixing the reformed gas converted in the part 1 with an oxidizing gas, an oxidizing gas supplying part 3 for supplying the oxidizing gas to the part 2, the CO oxidizing part 7 for decreasing carbon monoxide contained in the reformed gas with the oxidizing gas mixed in the part 2. An oxidizing gas introducing part 4 is arranged in the part 2 for introducing the oxidizing gas supplied from the part 3 into the part 2. The cross-sectional area of the part 4 in the direction orthogonal to a stream of the reformed gas is made smaller than that the part 1 in the direction orthogonal to a stream of the reformed gas so that the reformed gas can be mixed uniformly with the oxidizing gas.
