Abstract:
Different steam reforming experiments were carried out at 650 ºC and atmospheric pressure using a fixed bed reactor. A Ni-Co/Al-Mg catalyst and a W/morg ratio of 4 g catalyst min/ g organics were used. From the experiments it was found that the technology of pyrolysis and the kind of biomass had a significant influence on the steam reforming of their corresponding aqueous fractions of bio-oils at the experimental condition tested. Higher initial carbon conversion to gas and both H2 and CO2 yields were achieved when reforming both aqueous fractions obtained from pine bio-oil than those obtained from poplar bio-oil. In the case of reforming the pine aqueous fractions no significant differences were found between the two technologies of pyrolysis used. Oppositely when reforming the poplar aqueous fractions, significant differences were found. In this case, the aqueous fraction obtained from the bio-oil whose pyrolysis took place in the fluidized bed reactor, provided higher initial H2 and CO2 yields than the aqueous fraction of the bio-oil obtained in the spouted bed reactor. The temperature of pyrolysis also had a significant influence. An increase in the pyrolysis temperature produced an increase in the carbon conversion to gas and the H2 and CO2 yields.
