Kinetics of devolatilization of oil palm solid wastes using thermo-gravimetric analysis
The kinetics of the devolatilization of oil palm fibres and shells have been determined in a Thermo-Gravimetric Analyser (TGA). The TGA data indicate that the devolatilization process begins around 200°C and terminates around 600°C. The Differential Thermal Analysis (DTA) data indicate the existe...

| الملخص: | The kinetics of the devolatilization of oil palm fibres and shells have been determined
in a Thermo-Gravimetric Analyser (TGA). The TGA data indicate that the
devolatilization process begins around 200°C and terminates around 600°C. The
Differential Thermal Analysis (DTA) data indicate the existence of two different rates
of devolatilization with the turning point at around 350°C. The temperature at which
the maximum rate of weight loss occurs are around 315°C and 380°C. The kinetic
parameters, namely the activation energy and the ftequency factor, are determined
assuming a first order reaction. The data are compared to that of pure cellulose |
