Kinetics of in SITU transesterification using waste-derived catalyst for biodiesel production
A kinetic study of in situ transesterification of solid coconut waste was conducted at 55-65°C. The mixing is kept constant at 350 rpm. The maximum conversion of 38.3% was obtained at 60°C, 1:10 solid to methanol ratio and 5 weight (wt.) % of catalyst. The feedstock was obtained after coconut mil...

| Summary: | A kinetic study of in situ transesterification of solid coconut waste was
conducted at 55-65°C. The mixing is kept constant at 350 rpm. The maximum
conversion of 38.3% was obtained at 60°C, 1:10 solid to methanol ratio and 5
weight (wt.) % of catalyst. The feedstock was obtained after coconut milk
extraction. The conversion of solid coconut waste to methyl esters was analyzed
as function of temperature after 180 min of reaction. The experimental data
appear to be a good fit into a pseudo first order kinetic model for the three
stepwise reactions. The reaction rate constant, k and the activation energy, Ea
were determined. In this study, the activation energy obtained from the
experiment was 33.88 kJ/mol. |
