“…Table 6 shows the kinetic parameters obtained from the deconvolutions carried out on the DTG curves ( Figure 5 ). These kinetic parameters are in agreement with those published [ 53 , 54 , 55 , 56 , 57 ]. From the area obtained in the integration of each curve associated with the decomposition of the biopolymers, the biocomposition of each of the samples is determined considering their carbonisation performance ( Table 6 ).…”

This article is focused on the development of a series of biodegradable and eco-friendly biocomposites based on starch polymer (Mater-Bi DI01A) filled with 30 wt % almond shell (AS) of different varieties (Desmayo Rojo, Largueta, Marcona, Mollar, and a commercial mixture of varieties) to study the influence of almond variety in the properties of injected biodegradable parts. The different AS varieties are analysed by means of Fourier transform infrared spectroscopy (FT-IR), thermogravimetric analysis (TGA), Scanning Electron Microscopy (SEM), and X-ray Diffraction (XRD). The biocomposites are prepared in a twin-screw extruder and characterized in terms of their mechanical (tensile, flexural, Charpy impact, and hardness tests) and thermal properties (differential scanning calorimetry (DSC) and TGA). Despite observing differences in the chemical composition of the individual varieties with respect to the commercial mixture, the results obtained from the mechanical characterisation of the biocomposites do not present significant differences between the diverse varieties used. From these results, it was concluded that the most recommended option is to work with the commercial mixture of almond shell varieties, as it is easier and cheaper to acquire.

“…When the sample water content is less than 10%, they are generally suitable for combustion [32]. The initial start of depolymerization and volatile pyrolysis mainly appeared in the second stage with the cracking of small amount of low-polymerization hemicellulose and the polymerization reaction of some cellulose [33]. The maximum mass loss of the PSH in the two atmospheres occurred in the third stage, the depolymerization of the PSH and the pyrolysis of volatiles were considered to continue with the decomposing of lignin at the same stage.…”

The influences of four heating rates on the combustion and pyrolysis behavior in the N2 and air atmosphere were investigated by the Fourier transform infrared spectrometry (FTIR) and thermogravimetric (TG) analysis. the distributed activation energy model (DEAM) and Flynn-Wall-Ozawa (FWO) were used to estimate Ea and A, ΔH, ΔG and ΔS. Experimental results showed that the similar thermal behavior emerged, but the temperatures in the air and N2 atmospheres representing the end of the reaction were about 500 °C and 550 °C, respectively. The results of FTIR showed the peak positions were basically the same, but the concentrations of aromatics, aldehydes and ketones produced by pyrolysis in the N2 atmosphere were higher. When the heating rate was 20 K/min, the comprehensive combustion parameters were 56.442 and 6.871 × 10−7%2/(min2• K3) in the air and N2 atmospheres, respectively, indicating that the peanut shells had great potential to become bioenergy.

“…Table 2 summarizes the four reaction models that were used during the evaluation. The most complex is the distributed activation energy model (DAEM) developed by Anthony et al (1975) and successfully used multiple times for complex solid fuels (Várhegyi et al 2011;Cai et al 2013bCai et al , 2014Wu et al 2014;Zhang et al 2015;Lin et al 2018). It assumes that every reaction groups consist of an infinite number of sub-reactions, and their activation energies have a specific distribution, which is described by a D(E) distribution function.…”

The utilization of challenging solid fuels in the energy industry (especially the ones derived from wastes) has a big priority nowadays, as it is a valid option to keep the recent EU directive related to the decrease of landfills. However, there are serious technical challenges, connecting to the lack of knowledge about the behavior of these fuels in the combustion chamber. This paper discusses the specific aspects of developing particle models concerning the combustion of these non-conventional fuels. A new modeling approach is presented, using which it is possible to develop an all-round particle model that includes every significant influencing process. Moreover, it does not have any restrictions regarding the shape, size and the origin of the particle. As an integral component of this model, the distinctive aspects of intrinsic reaction kinetics related to waste fuels are presented as well.
