Thermodynamics Of Sorption

The reaction thermodynamics of sorption enhanced steam reforming (SESR) of acetic acid as a model compound of bio-oil for hydrogen production were investigated and contrasted with acetic acid steam reforming (SR). The most favorable temperature for SR is approximately 650 °C. However, the optimum temperature for SESR is around 550 °C, which is about 100 °C lower than that for SR. The highest hydrogen concentration from SR is only 67%, which is below the basic requirement of hydrogen purity for fuel cells. In SESR, hydrogen purities are over 99% in 500-550 °C with a calcium oxide to acetic acid molar ratio (CAMR) of 4 and a water to acetic acid molar ratio (WAMR) greater than 6. The results show that hydrogen production from sorption enhanced steam reforming of acetic acid should be a promising direction.

In our work, acetic acid was used as a bio-oil model compound. Thermodynamic calculation of hydrogen production via steam reforming of acetic acid was attempted to investigate the effects of temperature (200-1100 °C), pressure（1-19 atm ）and steam to carbon ratio (1.5-10.5) on the concentration of equilibrium product gas and H2 yield. The results show that temperature has a profound effect on the steam reforming of acetic acid. Lower pressure and higher steam to carbon ratio are in favor of higher hydrogen production.
