An improved adsorption process is provided for purifying hydrogen from a feed gas mixture including hydrogen and at least one impurity selected from the group consisting of carbon monoxide and nitrogen. The process includes providing an adsorption apparatus having a discharge end adsorption layer containing an adsorbent with a Henry's law constant (K H) at 70°F for the impurity from about 0.5 to about 2.4 mmole/g/atm. The product gas collected from the adsorption apparatus is high purity (99.99+%) hydrogen.
