Removal Of Hydrogen And Carbon Monoxide Impurities From Gas Streams

摘要

Hydrogen and carbon monoxide impurities are removed from a dry gas comprising the impurities, wherein the dry gas is at least substantially free of carbon dioxide, by passing the dry gas with sufficient residence time, e.g. at least 1.5 s, through a layer of catalyst comprising a mixture of manganese oxide and copper oxide. The use of expensive noble metal catalysts to remove hydrogen may thereby be avoided. In addition, regeneration of the catalyst using oxygen-containing regeneration gas does not reduce the effectiveness of the catalyst.

主权项

1. A process for removing hydrogen and carbon monoxide impurities from a dry gas comprising said impurities, wherein said dry gas is at least substantially free of carbon dioxide, said process comprising passing said dry gas through a layer of catalyst comprising a mixture of manganese oxide and copper oxide, with sufficient residence time to produce product gas that is at least substantially free of hydrogen and carbon monoxide.
