A comprehensive kinetics study of coconut shell waste pyrolysis.

•Integral model-fitting methods are more accurate for one-step reaction mechanism.•f(α)=(1-α)4·[-ln(1-α)]0.53 is the reaction model of CSW pyrolysis.•Four independent-parallel-reaction model fits well with Gaussian distributions.•Ea of pseudo-components can be reliably estimated from model-free methods.
