Chapter 4 - Summary of research on biochar adsorption of chemical pollutants

Double-heating, or “post-pyrolysis air oxidation”

Now we’re beginning to come full-circle, back to the discussion of why and how semi-aerobic gasification biochars outperform biochars produced by conventional anaerobic pyrolysis as adsorbents. The enhanced adsorption capacity of gasifier and “double heated” biochars has inspired deep dives into how air oxidation during or after pyrolysis affects biocha…
