A steam methane reforming process for producing a hydrogen product while capturing CO 2 from the process. Steam and a hydrocarbon are reformed in a catalytic reformer. The reformate is separated by pressure swing adsorption to form the hydrogen product and a PSA tail gas. The tail gas is returned to the reformer as a fuel. The fuel is combusted with synthetic air where the synthetic air is formed by combining a portion of the flue gas with industrial grade oxygen. The flue gas consists essentially of CO 2 and H 2 O. The H 2 O is condensed out of another portion of the flue gas to form an essentially pure CO 2 product.
