Sorption enhanced catalytic steam reforming of blends of bio-oil model compounds for hydrogen production

Abstract

The objective of the present study was to investigate the effect of reaction temperature on H2 production by sorption enhanced steam reforming of bio-oil over a Pd/Ni-Co hydrotalcite-derived catalyst and using dolomite as CO2 sorbent. Experiments were carried out in a fluidized bed reactor at temperatures between 525 and 725 °C. In order to simulate bio-oil behavior, acetic acid, acetone, phenol and blends of the three model compounds were tested. Analysis of the thermodynamic equilibrium of the process was conducted by means of Aspen Plus software in order to assess the theoretical feasibility of the process.
