“…(5a)-(5b), are presented in Table 2. The tabulated results show that the values of the activation energy and the frequency factor for the two samples in this study are lower than those obtained by Min et al (2007), Caballero et al (1997 and Cao et al (2004) but higher than those obtained by Peng et al (2001) in both the lower and higher temperature regions. This may be due to the fact that the kinetic parameters determined by the studies were for biomass solid waste of different compositions.…”

In this study pyrolysis kinetics of jute stick (white jute: Corchorus capsularis; tossa jute: Corchorus olitorius) and tamarind (Tamarindus indica) seed available in Bangladesh have been investigated thermogravimetrically in a nitrogen atmosphere at heating rates of 10 and 60 o C/min over a temperature range of 30 to 800 o C. The two biomass solid wastes exhibited similar behaviors in that, the weight loss region is shifted to a higher temperature range and the weight loss rate is increased with increasing heating rate. The percentage of total weight loss is higher for jute stick and is lower for tamarind seed. The overall rate equation for the two biomass wastes has been modeled satisfactorily by one simplified equation from which the kinetic parameters of unreacted materials based on the Arrhenius form can be determined. The predicted rate equation compares fairly well with the measured TG and DTG data.

“…Comparison of various kinetic parameters including decomposition temperatures and activation energy of pyrolysis for different biomass [11,22,[28][29][30][31][32][33][34]. The results indicated that the decomposition temperature of P. australis is higher than that of algae and lower than that of the higher plants.…”

The pyrolytic characteristics and kinetics of wetland plant Phragmites australis was investigated using thermogravimetric method from 50 to 800°C in an inert argon atmosphere at different heating rates of 5, 10, 25, 30, and 50°C min -1 . The kinetic parameters of activation energy and frequency factor were deduced by appropriate methods. The results showed that three stages appeared in the thermal degradation process. The most probable mechanism functions were described, and the average apparent activation energy was deduced as 291.8 kJ mol -1 , and corresponding pre-exponential factors were determined as well. The results suggested that the most probable reaction mechanisms could be described by different models within different temperature ranges. It showed that the apparent activation energies and the corresponding preexponential factors could be obtained at different conversion rates. The results suggested that the experimental results and kinetic parameters provided useful information for the design of pyrolytic processing system using P. australis as feedstock.

“…Chlorella protothecoides were pyrolyzed at the heating rates of 15, 40, 60, and 80 ° C/min up to 800 ° C. The pyrolysis reactions mainly took place between 160 -520 ° C with a volatile yield of about 80%. The devolatilization stage consisted of two main temperature zones (I and II) with a transition at 300 -320 ° C. The researcher found that crude lipid in cells decomposed at Zone II while other main components at Zone I, which might indicate that more energy input for lipid pyrolysis seems needed in comparison with other main components (Peng et al 2001b ). In another study, two kinds of high protein and lipid contents microalgae, Cyanobacterium Spirulina platensis (SP) and green alga C. protothecoides (CP) were pyrolyzed at the heating rates of 15, 40, 60, and 80 ° C/min up to 800 ° C in the thermogravimetric analyzer to investigate their pyrolytic characteristics.…”
