CARBON MONOXIDE REFORMER

摘要

PROBLEM TO BE SOLVED: To efficiently obtain high purity hydrogen with compact and simple equipment by passing a reformed gas obtained by steam reforming of fuel for hydrogen production through a carbon monoxide reforming catalyst bed and providing a hydrogen separation chamber with a hydrogen separation membrane interposed in the boundary surface in the catalyst bed. SOLUTION: The flat carbon monoxide reforming catalyst bed 1 is sealed in a cubic casing 10 and a cooling device composed of water jackets 3 and 3 is arranged to be in close contact with the upper and lower sides thereof. The carbon monoxide reforming catalyst bed 1 is composed of a carbon monoxide reforming catalyst of an iron.chromium base or the like, the hydrogen separation chamber 8 is provided therein and the hydrogen separation membrane 2 composed of a thin film of palladium, a palladium alloy or the like is interposed in the boundary between the catalyst bed 1. The reformed gas obtained by the hydrogen reforming or the like of the fuel for hydrogen production flows in the carbon monoxide reforming catalyst bed 1 to react at 320-450 deg.C while being cooled by a cooling device to be converted to hydrogen. The hydrogen is selectively passed through the hydrogen separation membrane 2 to be taken out as pure hydrogen containing <=10 ppm CO from an outlet 5 of the hydrogen separation chamber 8.
