Abstract

A steam methane reforming process for producing a hydrogen product while capturing CO2 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 CO2 and H2O. The H2O is condensed out of another portion of the flue gas to form an essentially pure CO2 product.
