Abstract
A system for production of hydrogen comprises at least one steam reforming zone configured to receive a first fuel and steam to produce a first reformate gas stream comprising hydrogen using a steam reforming process. The system further comprises a mixed reforming zone configured to receive an oxidant to produce a second reformate gas stream comprising hydrogen, wherein the first reformate gas stream is sent to the mixed reforming zone to complete the reforming process.
Claims28
A system for production of hydrogen comprising:
- at least one steam reforming zone configured to receive a first fuel and steam to produce a first reformate gas stream comprising hydrogen using a steam reforming process;
- and
- a mixed reforming zone configured to receive an oxidant to produce a second reformate gas stream comprising hydrogen;
- wherein said first reformate gas stream is sent to said mixed reforming zone to complete said reforming process.
The system of claim 11, wherein said off gas is recycled to said combustor to transfer heat from said combustor to said at least one steam reforming zone.
A system for production of hydrogen comprising:
- at least one steam reforming zone configured to receive a first fuel and steam to produce a first reformate gas stream comprising hydrogen in a reforming process;
- a first catalytic oxidation zone and a second catalytic oxidation zone, wherein said first catalytic zone is configured to receive a heated oxidant and a second fuel to produce a second reformate gas stream comprising hydrogen and said first reformate gas stream is sent directly to said second catalytic partial oxidation zone to complete said reforming process;
- and
- a heat exchange zone and a shift zone, wherein said heat exchange zone is configured to receive an oxidant and said second reformate gas stream, wherein heat is transferred from said second reformate gas stream to said oxidant to generate a cooled second reformate gas stream and said heated oxidant.
A method for producing hydrogen comprising
- steam reforming a first fuel to produce a first reformate gas stream comprising hydrogen;
- partially oxidizing a second fuel and an oxidant in a first catalytic partial oxidation zone to produce a second reformate gas stream comprising hydrogen;
- introducing said first reformate gas stream to a second catalytic oxidation zone;
- and
- introducing a mixture of said first reformate gas stream and second reformate gas stream to a shift zone to produce a third reformate gas stream rich in hydrogen.
