Comparative characterization of biochars produced at three selected pyrolysis temperatures from common woody and herbaceous waste streams.

ABSTRACT: Biochar, the product of biomass pyrolysis, has been explored as a soil amendment and carbon capture vessel. Recent literature has aligned biochar as a novel sorbent for a host of environmental contaminants. Through the variation of pyrolysis conditions, biochars can be engineered to have qualities desirable in sorbents whilst maintaining their agronomic benefits. This study focuses on identifying the effects that feedstock type and process temperature have on biochar characteristics which may in turn shed light on their potential environmental applications. Using this approach, six biochars were created from two waste biomasses. The biochars exhibited wide ranges of pH (5.6-11.1), surface area (16.2-397.4 m²/g), electrical conductivity (19-2,826 µS/cm), fixed carbon (72-97%), he
