Degradation Kinetics of Coconut Chaff in Subcritical Water

Abstract:

Using the Coconut chaff bran of grain size of 40 mesh as raw material, we carried out the subcritical hydrolysis experiment in 0-60 min, the reaction liquid ratio is 1:30. We establish its dynamic model by the experimental data fits subcritical hydrolysis reaction kinetic parameters. The study show that degradation temperature is the most significant factor which influences the degradation of the target product. The initial degradation activation energy of Coconut chaff Ea₁ is 68.35 KJ/mol and reducing sugar degradation activation energy Ea₂ is 83.27KJ/mol. And the pre-exponential factor K₁₀ is 3.16×10⁸h^-1 , K₂₀ is 5.56×10⁹h^-1_.
