Abstract
► Catalytic microwave pyrolysis of biomass was used with activated carbon as a catalyst. ► High concentrations of phenol (39%) and guaiacols+phenols (67%) in bio-oil were achieved. ► This is the first report where activated carbon has been used for phenol and phenolics production via microwave-induced pyrolysis.
Catalytic microwave pyrolysis of biomass using activated carbon was investigated to determine the effects of pyrolytic conditions on the yields of phenol and phenolics. The high concentrations of phenol (38.9%) and phenolics (66.9%) were obtained at the temperature of 589
K, catalyst-to-biomass ratio of 3:1 and retention time of 8
min. The increase of phenol and its derivatives compared to pyrolysis without catalysts has a close relationship with the decomposition of lignin under the performance of activated carbon. The concentration of esters was also increased using activated carbon as a catalyst. The high content of phenols obtained in this study can be used either directly as fuel after upgrading or as feedstock of bio-based phenols for chemical industry.
