  • Integrated pressurized steam hydrocarbon reformer and combined cycle process
    Patent number: 8375725
    Abstract: A process for the co-production of hydrogen and power through the integration of a hydrogen production unit and a power generation unit is provided. The hydrogen production unit comprises a gas heated reformer, a water gas shift reactor, and a hydrogen separator which produces a low-BTU hydrocarbon fuel stream and a purified hydrogen stream. The low-BTU hydrocarbon fuel stream, along with a compressed oxygen-containing stream extracted from the power generation unit, is combusted to provide heat to the reformer.
    Type: Grant
