An apparatus and method for purifying a raw hydrogen gas stream of chloramines and chlorine is provided. The explosive chloramines compounds can be effectively captured by the carbon adsorbent without accumulating on the carbon surface. Rather, the chloramines are converted via decomposition, into non-explosive products with catalytic effect of the carbon material. Chlorine reacts with impregnated reducing agent on the carbon surface to form the solid products, which can be adsorbed on the carbon surface. The purified hydrogen gas contains little to no trace of chloramines and chlorine impurities, thereby making the hydrogen gas suitable for liquid hydrogen production.
