Abstract

The design of a layered pressure swing adsorption unit to treat a specified off-gas stream is based on the properties of the adsorbent materials. In this work we provide adsorption equilibrium and kinetics of the pure gases in a SMR off-gas: H2O, CO2, CH4, CO, N2, and H2 on two different adsorbents: activated carbon and zeolite. Data were measured gravimetrically at 303-343K and 0-7bar. Water adsorption was only measured in the activated carbon at 303K and kinetics was evaluated by measuring a breakthrough curve with high relative humidity. © Taylor & Francis Group, LLC.
