ABSTRACT:
A gas adsorption composite a high density adsorbent including a high density layer having a first density of at least 0.3 g/cc; and a low density adsorbent having a low density layer having a second density of less than 0.3 g/cc, wherein the high density adsorbent is in substantially contiguous contact with the low density adsorbent and each of the high density adsorbent and the low density adsorbent has an adsorbent surface area of at least 500 m2/g. A pressure swing adsorption process for recovering a product gas from a feed gas, the process including supplying a pressure swing adsorption apparatus including a gas adsorption composite, feeding a feed gas into the pressure swing adsorption apparatus during a feed period not exceeding 100 seconds and recovering the product gas from the pressure swing adsorption apparatus.
