Abstract

H₂ production from a biomass fermentation process provides a great opportunity for green and sustainability economy compared to use fossil fuels (e.g., steam methane reforming process), but the process usually produces a humidified gas containing 35–65 (vol.%) H₂ and 40–50 (vol.%) CO₂. A novel, energy efficient two-stage carbon membrane system for H₂ purification based on the combination of H₂ selective carbon molecular sieve membranes in the first stage and CO₂ selective carbon membranes in the second stage was proposed. The concept is the first unique technology providing a low H₂ purification cost <1 $/kg H₂ produced at a feed pressure of 20 bara based on process simulation and cost estimation. The produced high purity CO₂ (>95 vol.%) and H₂ (>99.5 vol.%) can be integrated into a gasification reformer and Fischer-Tropsch reactors to improve the biodiesel productivity from biomass.
