  • Hydrogen production via sorbent enhanced reforming with atmospheric calcination
    Patent number: 10227234
    Abstract: Processes and systems for producing hydrogen gas utilizing a sorbent enhanced reformer in combination with a calciner operating at atmospheric pressure. Feed material is introduced into the sorbent enhanced reformer to produce carbon dioxide and hydrogen gas. Sorbent material within the reformer acts to absorb carbon dioxide and form a used sorbent. The used sorbent is introduced into the atmospheric calciner to heat the used sorbent to desorb carbon dioxide from the used sorbent to produce regenerated sorbent which can be recycled to the reformer.
    Type: Grant
