Char yield on pyrolysis of cellulose

Abstract

Whether the pyrolysis of cellulose is conducted in an inert medium or in air, partial pyrolysis at a lower temperature increases the char yield subsequently obtained after 1 hour at 370°C. The results are consistent with a pyrolysis scheme in which two competing sequences of cellulose pyrolysis reactions are initiated by (1) an intermolecular dehydration leading to char formation and, in air, to glowing combustion; and (2) a char-free depolymerization leading, in air, to flaming combustion.
