Adsorbents for hydrogen recovery by pressure swing adsorption
摘要
<p>Hydrogen is purified from a feed gas mixture including hydrogen and at least one impurity selected from carbon monoxide and nitrogen using an adsorption apparatus having a discharge end adsorption layer containing an adsorbent with a Henry's law constant (KH) at 70 DEG F (21 DEG C) for the impurity from 0.8 to 2.2 mmole/g/atm (0.1 MPa) for carbon monoxide or from 0.55 to 1.4 mmole/g/atm (0.1 MPa) for nitrogen. High purity (99.99+%) hydrogen can be obtained.</p>
