  • Hydrogen generation process with dual pressure multi stage electrolysis
    Patent number: 7976693
    Abstract: A multi-pressure hybrid sulfur process (2) contains at least one electrolyzer unit (16) which provides liquid H2SO4 to a preheater/vaporizer reactor (20) operating at a pressure of from 1 MPa to 9 MPa to form gaseous H2SO4 which is passed to a decomposition reactor (14) operating at a pressure of from 7 MPa to 9 MPa, where decomposed H2SO4 is passed to at least one scrubber unit (14) and at least one electrolyzer unit (16) both preferably operating at a pressure of 0.1 MPa to 7 MPa, where an associated Rankine Cycle power conversion unit (50) supplies electricity.
