Herstellung von Wasserstoff mittels Druckwechseladsorption durch Verwendung von einem mehrschichtigen Adsorptionsbett |
摘要 |
The present invention describes a pressure swing adsorption (PSA) apparatus and process for the production of purified hydrogen from a feed gas stream containing heavy hydrocarbons (i.e., hydrocarbons having at least six carbons). The apparatus comprises at least one bed containing at least three layers. The layered adsorption zone contains a feed end with a low surface area adsorbent (20 to 400 m<2>/g) which comprises 2 to 20% of the total bed length followed by a layer of an intermediate surface area adsorbent (425 to 800 m<2>/g) which comprises 25 to 40 % of the total bed length and a final layer of high surface area adsorbent (825 to 2000 m<2>/g) which comprises 40 to 78% of the total bed length. |
