Thermogravimetric analysis on global mass loss kinetics of rice hull pyrolysis

摘要

Pyrolyses of rice hulls were performed in a thermogravimetric analyzer from room temperature to 1173 K at heating rates of 10, 30, 60, and 100 K/min. The global mass loss during rice hull pyrolysis ws modeled by a combination of the volatile evolutions of four independent parallel lumps: one form moisture and the other three for nomoisture volatiles. The decomposition of each lump was characterized by a single reaction, first-order with respect to the amount of volatile yet to evolve.
