Method for creating hydrogen by water gas shift reaction at very low temperatures

摘要

The biological conversion of carbon-containing feed materials into a hydrogen-enriched product gas, comprises producing a synthetic raw gas, which contains hydrogen and carbon monoxide, from carbon-containing feed materials and subjecting the synthetic raw gas in a catalytically supported water-gas shift reaction for increasing the hydrogen proportion. The water-gas shift reaction is carried out in a supported ionic liquid phase reactor at 60-150[deg]C and 1-5 bar. In the reactor, a suitable catalyst is present within a liquid ionicaly immobilized on a substrate.

The water-gas shift reaction is carried out in a supported ionic liquid phase reactor at 60-150[deg]C and 1-5 bar. In the reactor, a suitable catalyst is present within a liquid ionicaly immobilized on a substrate. The feed materials are transferred with low pressure of less than 12 bar by pyrolysis of synthetic raw gas, which is supplied through a bypass to the water gas shift reactor and which is combined with the product gas from the shift reactor to a hydrogen-enriched product gas. The size of the bypass stream is regulated in such a manner that the hydrogen/carbon monoxide-ratio in the hydrogen-enriched product gas represents a defined value.
