Cover Story: Pyrolysis of pine wood sawdust, charged/or not with activated carbon (AC), was carried out using microwave (MW) technology. Experimental conditions were consisted 20 min processing time, 0 wt.% and 10 wt.% of AC, and a MW power varying from 100 to 800 W. The results obtained showed that the MW absorber allowed increasing the bio-oil yield up to 2 folds by reducing the charcoal fraction. The higher heating values of the solid residues were ranged from 17.6 to 30.3 MJ/kg. Furthermore, the addition of AC allowed showing the probable catalytic effect of the AC in the charged sample pyrolysis bio-oils. View this paper
