“…The biomass pyrolysis concept for this study is based on the fact that the precise mechanism is not clearly known because of extremely complex reactions that take place during the biomass pyrolysis process (Ioannidou et al, 2011). A simplified two-step concept of the pyrolysis was introduced to consider possible secondreaction which is affected by operating condition as Fig.…”

“…The model enabled the possibility to evaluate a mass balance during the thermal treatment of the residue. However, the model did not take into account the possible activity of a second reaction (Ioannidou et al, 2011) which can possibly come from a variation in operating conditions. Also, it is still far from being applied in a fluidized bed pyrolyzer due to different operating principles between reactor types.…”

“…These values are essential as certain moisture, volatile matter and fixed carbon affect both thermal behavior and plant design (Garcia et al, 2013). Recently, a thermogravimetric model for pyrolysis product distribution in a captive batch reactor was proposed based on the proximate analysis of three agricultural residues (Ioannidou et al, 2011). The model enabled the possibility to evaluate a mass balance during the thermal treatment of the residue.…”

“…Especially, the pyrolytic oil yield in a fluidized bed is affected by the fluidizing conditions, such as gas velocity, the physical properties of bed material and static bed height or vapor residence time (Cui and Grace, 2007). Therefore, biomass thermochemical conversion development requires methodologies for prediction of the product distribution, whereby an appropriate balance between empiricism and fundamentals related with characteristics of biomass and flow dynamics should be considered to describe the complex range of interrelated phenomena (Ioannidou et al, 2011).…”

“…In addition, various mathematical approaches can be adopted in combination, in order to improve the calculation accuracy of kinetic parameters of biomass pyrolysis. Some studies have also been conducted to investigate the reaction order of the three biochemical composition of biomass [63][64][65][66][67]. Theses researches reported that the pyrolysis of cellulose can be described by the first order of reaction, whilst the three-order reaction may be the most suitable assumption for the lignin component, according to the results other authors investigated the pyrolysis of hemicellulose employing the assumption of second reaction order, and observed that the hemicellulose of different biomass materials differed greatly in reaction order.…”

Journal of Advanced Chemical Engineering AbstractIn this study, the thermal behavior of two olive mill wastes samples such as olive mill solid waste (OMSW) and concentrated olive mill wastewater (COMWW) was examined at different heating rates ranging from 5 to 50 K/min in inert atmosphere using the technique of thermo gravimetric analysis. Avrami theory and iso-conversional Starink approach were used in this work to evaluate the kinetic parameters, including apparent activation energy (E a ) and reaction order (n). For the range of conversion degree investigated (20-80%), the values of apparent activation energy for olive mill solid waste (OMSW) were 147.51-158.79 KJ/mol and 200.13-212.51 KJ/mol for hemicellulose and cellulose respectively. Whilst the apparent activation energy of concentrated olive mill wastewater (COMWW) varied from 128.41 to 138.85 KJ/mol and from 201.3 to 226.67 KJ/mol for hemicellulose and cellulose respectively. With varied temperature (515-753 K), the corresponding values of reaction order was increased from 0.1004 and 0.1061 to 0.1787 and 0.2886, along with a decrease to 0.1220 and 0.1889 for OMSW and COMWW respectively.

Hydrothermal Carbonization‐Derived Carbon from Waste Biomass as Renewable Pt Support for Fuel Cell Applications: Role of Carbon Activation

et al. 2019

Pt catalysts in proton exchange membrane fuel cells (PEMFCs) typically use carbon blacks such as Vulcan (Vulcan is a registered trademark of the company Cabot Corporation) based on fossil sources. Thus, an important research task is using sustainable supports in PEMFCs. Hydrothermal carbonization (HTC) converts biomasses into chars, which are possible substitutes for fossil‐based carbons. Herein, a Pt catalyst derived from HTC of coconut shells is developed for catalysis of O2 reduction in acidic media. Thermal activation enlarges the specific surface area by factor of 7 to 546 m2 g−1 and generates electrical conductivity making the material suitable for catalysis. Pt particles of 1.8 ± 0.5 nm are distributed well on the activated carbon. Cyclic and CO stripping voltammetry show an electrochemical surface area (ECSA) of 69 ± 21 m2 gPt−1, almost identical to that of the commercial catalyst using Vulcan (69 ± 6 m2 gPt−1). Although ECSAs are highly comparable, the activity for O2 reduction is lower compared with the commercial catalyst. HTC‐derived carbon has a lower degree of graphitization, less functional oxygen groups on its surface, and a lower electrical conductivity than Vulcan. This suggests different Pt–support interactions.
