Hydrogen production from biomass are one of most promising carbon nertual fuels and sustainable development. CO2 capture and sequestration is combined with hydrogen production from biomass to improve hydrogen productivity and to reduce CO2 emission released into atmosphere.
Hydrogen production from bio-oil aqueous fraction, which made from rice hull through a fast pyrolysis process, via catalytic steam reforming and CO2 adsorption was carried out in a bench scale fixed-bed reactor. Effects on several different catalysts and sorbents on hydrogen productivity were performed. Introducing sorbents to capture CO2 during the reaction increased hydrogen yield as well as hydrogen content in produced gases. Influence of deposition of carbon on the catalyst and adsorbent deactivation was investigated. Thermodynamics analysis of hydrogen production gives maximum hydrogen yield for bio-oil with some heat value.
