摘要
[Objective] The paper aimed to study kinetics analysis of coconut shell pyrolysis. [Method] Thermo gravimetric analysis was used to study the pyrolysis characteristic of coconut shell at different pyrolysis rates (5, 10, 20 K/min). [Result] The pyrolysis process included 3 stages, water loss, pyrolysis, and thermal condensation. The pyrolysis process can be described through first-order reaction model. With the increasing pyrolysis rate, activation energy in the first stage rose, but activation energy in the second stage reduced. [Conclusion] The study provided theoretical basis for the promotion and application of biomass energy.
