Catalytic reforming of acetic acid as a model compound of bio-oil for hydrogen production over Ni-CeO2-MgO/olivine catalysts

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.

AbstractOlivine is abundant in the Earth’s upper mantle; it has applications in catalysts to enhance their stability in structures. The olivine-type catalysts were prepared by co-precipitation and hydrothermal synthesis and tested in the auto-thermal reforming (ATR) of acetic acid (AC), a model compound from bio-oil, for hydrogen production. In the meantime, the natural olivine impregnated with Ni was also tested. Characterisations of XRD, nitrogen physisorption, temperature-programmed reduction, and SEM-EDX were used to find the structure-reactivity relationship. The results indicate that the natural olivine produced a low H
