“…Thermal diffusivity data can be used to determine the duration of thermal processes (Mahapatra et al, 2013). The thermal properties of food products can be measured directly, with the use of different devices and techniques such as an analyser KD2 Pro and thermal analysis (Lever et al, 2014;Barnwal et al, 2015;Perussello et al, 2015), and indirectly using mathematical calculations based on the chemical composition (water, protein, fat, carbohydrates, fibre and ash), temperature and structure of the analysed material (Choi, Okos, 1986;Sahin, Sumnu, 2006;Wang et al, 2008;Carson, 2015). Therefore, some of our findings can be used for mathematical modelling.…”

The aim of this study was to compare the thermal, physical, mechanical and chemical properties of white mustard (Sinapis alba L.) seeds of the traditional cultivar 'Radena' and the double low cultivar 'Warta'. The selected thermal properties were determined with an analyser KD2 Pro. Cultivar 'Warta' was characterised by higher thermal conductivity (0. ). Cultivars 'Warta' and 'Radena' had identical thermal diffusivity (0.087 mm 2 s -1 ). The values of the highest initial endothermic peaks and the last endothermic peak were determined from differential scanning calorimetry curves. The mean values of common peaks for both cultivars were determined at −17.5, 86.0 and 402.3 °C for 'Warta', and −16.5, 69.9 and 400

“…In the latter case the equipment regulated the heating of the samples so that the reaction rate remained below a small preset limit. 19 This type of measurements falls into the category of the controlled rate thermal analysis (CRTA) by the current IUPAC nomenclature. 20 The employment of the different heating programs served to increase the information content of the experiments for the kinetic evaluation.…”

Combustion Characteristics of Biomass Charcoals Produced at Different Carbonization Conditions: A Kinetic Study

ABSTRACT. The combustion properties of spruce chars and spruce forest residue chars were studied in the kinetic regime by a series of TGA experiments. The work aimed at establishing how the pressure of the char preparation affects the reactivity with oxygen. Parts of the chars were prepared from a thin layer of biomass in inert gas flow at atmospheric pressure and at 0. in the preparation, remarkable similarities were observed in the combustion behavior of the samples. The kinetics of the char burn-off was described by assuming three partial reactions. 18 experiments at three different temperature programs were evaluated by the method of least squares to obtain dependable kinetic model variants. A common activation energy of 150 kJ/mol gave a reasonable description for the three partial reactions in all experiments.

“…These methods study the relationship between sample property and its temperature as the sample is heated or cooled in a controlled manner. The individual techniques are divided according to the measured property 12 [131], [132], [130] as is introduced in Table 1. The measurement should be performed as follows:…”

Apatites and Their Synthetic Analogues - Synthesis, Structure, Properties and Applications

View full text Add to dashboard Cite

The parameters of unit cell, structure, refractive index, solubility data, PO 4 /CO 3 ratio, surface area, etc., are important parameters for characterization of phosphate rocks. Third chapter of this book introduces methods for identification, characterization and properties of apatites in four main sections. The first part describes techniques used for identification and investigation of properties of phosphate minerals, including X-ray diffraction analysis, powder neutron diffraction, X-ray fluorescence as well as spectroscopic and microscopic methods. Some of these techniques are then demonstrated on the fluorapatite specimen in the second part. The third part of this chapter deals with thermodynamic properties of apatite-type compounds and introduces some of thermodynamic predictive methods. The fourth part is dedicated to dissolution of apatite, where the reaction between solids and liquids according to different dissolution models is described. Chapter ends with methods for the evaluation of reactivity of phosphate rocks.
