Abstract
A method and apparatus for separating gas mixtures containing synthesis gas (syngas) into separate streams of wet hydrogen containing significantly reduced amounts of CO and CO, with the CO being “sequestration ready” and containing less than 1% fixed gases. In the preferred embodiment, a mixture of limestone and iron oxide circulates between two fluidized beds whereby one bed is fluidized with a gas containing syngas, while the other bed is fluidized with a gas containing steam and oxygen. As the fluidizing gas containing syngas passes through the bed, the CO reacts with CaO to form CaCO . Virtually all of the CO is removed by a water gas shift reaction, forming hydrogen and CO , with the remainder being removed by reaction with the iron oxide, reducing Fe O to FeO. Some hydrogen is also removed by reaction with the iron oxide, reducing Fe O to FeO, while the remainder of the hydrogen passes through the fluid beds, leaving in a purified state, i.e., PEM fuel cell quality.
