“…This phenomenon is common to biomass pyrolysis [22]. This is because the increased heating rate provided higher thermal energy to facilitate better heat transfer between the surroundings and the samples [23,24]. Figure 1 showed that the first stage is an endothermic process which confirmed that is a stage of dehydration and need to absorb heat.…”

Macrocystis pyrifera is one important marine macro-algae, while its residues produced by industrial alginate extraction is a hot potato. To figure out whether its residue is suitable for pyrolysis for biofuel, the pyrolytic characteristics and kinetics of macro-algae M. pyrifera residue was investigated using thermogravimetric method from 50 to 800°C in an inert argon atmosphere at different heating rates of 5, 10, 20, and 30°C min -1 . The activation energy and pre-exponential factor was calculated by FlynnWall-Ozawa, Kissinger-Akahira-Sunose, and Popescu methods, and the kinetic mechanism was deduced by Popescu method. The results showed that the primary devolatilization stage of M. pyrifera residue can be described by. The average activation energy of M. pyrifera residue was 222.4 kJ mol -1 . The results suggested that the experimental results and kinetic parameters provided useful information for the design of pyrolytic processing system using M. pyrifera residue as feedstock.

“…It showed a higher amount of ash and cellulose contents compared with other terrestrial materials (Olive residues that study by A. Aboulkas, and pistachio shell that study by Korkut Açıkalın) that came from other literatures [36,37]. The volatile matter and lignin contents of P. australis were lower, while the sulfur content of the samples was approximately equal [11][12][13].…”

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.

“…6 demonstrated the kinetic compensation effects during the pyrolysis of (a) RS, (b) RM, (c) CS, and (d) CM at different heating rates. The kinetic compensation effect (KCE) will always exist under different experimental conditions, such as different heating rates (Açıkalın, 2012), different reaction atmospheres (Wang et al, 2012), and different kinetic models used (Budrugeac and Segal, 2001). As seen from Table 4, the pre-exponential factor A and activation energy E displayed the same variation trend as the heating rate changed.…”
