摘要： Hydrogen sulfide is removed from a hydrogen rich gas stream using adsorbents having a low loss of carbon dioxide adsorption capacity upon sulfur loading including high purity silica gels, titania or highly cross-linked, non-chemically reactive resins. The adsorbents may be used to adsorb both carbon dioxide and hydrogen sulfide, or may be used as a guard bed upstream of a separate carbon dioxide adsorbent.

摘要： The present invention provides a pressure swing adsorption process. The process includes providing a pressure swing adsorption apparatus having a discharge end adsorption layer of activated carbon, feeding through the apparatus a feed gas including hydrogen, carbon monoxide and at least one of argon and oxygen, and collecting a product gas from the apparatus, wherein the product gas is high purity hydrogen. Also provided is a method for decreasing an amount of impurities in a product gas from a pressure swing adsorption process for separating hydrogen from impurities including carbon monoxide, and at least one of argon and oxygen. The method includes providing an improved adsorption layer in at least a discharge end of a pressure swing adsorption apparatus in which the pressure swing adsorption process is conducted, wherein the improved adsorption layer includes activated carbon in an amount effective to: (a) decrease the amount of impurities in the product gas; (b) increase a time until initial impurity breakthrough; and (c) improve hydrogen recovery of the process.
