Biochar production through slow pyrolysis of different biomass materials: Seeking the best operating conditions

摘要

1.The R_(50) index and the stable C fraction (after oxidation with H_2O_2) appear as useful indicators of the potential stability of biochar. Both techniques are relatively fast and inexpensive compared to e.g. ~(13)C NMR. 2.Pressure has a little effect on potential stability compared to Peak Temperature. However, working at moderate pressure (1.0-1.5 MPa) leads to higher yields of produced gas as well as an improvement of its composition.
