Abstract

TG/DTG was applied to study the overall kinetics for the reduction of pyrolusite by the mixture of cellulose and lignin, two major components of biomass. The respective reduction processes can be described by a new empirical equation based on the JMA equation, and the apparent activation energy is 38.66 kJ•mol-1 and 38.91 kJ•mol-1 for the reduction of pyrolusite by cellulose and lignin, respectively. Overall reduction processes of pyrolusite by the mixture of cellulose and lignin are the partial overlapped reduction processes of pyrolusite by cellulose and lignin. This overall reduction processes can be simulated by the summation of the respective kinetics by considering their mass-loss fractions.
