| Abstract: | An experimental study of the separation of a binary mixture of methane and carbon dioxide by pulsed pressure swing adsorption in a single isothermal column packed with an activated carbon adsorbent revealed that a product containing 72% methane could be obtained from a feed mixture containing only 44% methane. When a 5A zeolite was used as adsorbent, the product contained more than 92% methane, the initial feed mixture being only 46% methane. A mathematical model of the process operation is shown to be in general agreement with the experimental results obtained. |
