Abstract
The present disclosure is directed to systems and methods for actively controlling the steam-to-carbon ratio in hydrogen-producing fuel processing systems that include a feedstock delivery system. The feedstock delivery system supplies a combined feedstock stream including steam and carbon-containing feedstock to a hydrogen-producing region, which produces a mixed gas stream including hydrogen gas as a majority component therefrom. The systems and methods may include measuring a thermodynamic property of a steam stream, a carbon-containing feedstock stream, and/or the combined feedstock stream and controlling the flow rate and/or pressure of a water stream, the steam stream, and/or the carbon-containing feedstock stream based on a desired steam-to-carbon ratio in the combined feedstock stream and/or a desired flow rate of the mixed gas stream and may include feedforward and/or feedback control strategies.
