Role of dolomite as an in-situ CO2 sorbent and deoxygenation catalyst in fast pyrolysis of beechwood in a bench scale fluidized bed reactor

The dual effect of dolomite as a CO2 sorbent and deoxygenation catalyst in fast pyrolysis beechwood was investigated. Investigation performed on bench scale fluidized bed reactor at an temperature 500 °C different WHSV. breakthrough curves bio-oil samples were produced simultaneously. results show that is both feasible it moderately deoxygenated free H2 rich gas. Acids eliminated, whereas the concentration methylated phenols cyclopentanones enhanced. These achieved when rapid carbonation stage prevailing throughout experimental run. An organic with 9.46 wt% yield HHV 28.0 MJ/kg (as received) obtained. pH catalytic increased from 3.2 to 6.0 oxygen content reduced 21.5 47.3 wt%. Moreover, interest can undergo downstream reforming into wide range liquid fuels consumption. Calculations generated result sorption suffice requirement for hydrodeoxygenation. In addition catalysts also characterized by BET, XRD SEM analysis.
