crystallization study using different methods for the same experimental data of a glass. The present work studies the crystallization kinetics and evaluates the activation energies for the Se 70 Te 15 In 15 glass under non-isothermal conditions. Using DSC scans

Estimation of activation energies The main objective of this part of the study is to show the catalytic activity of the nanoparticles toward asphaltene decomposition. Activation energy ( E a ) can be calculated by processing the data of simultaneous

understand bitumen pyrolysis. Distributed activation energy model (DAEM) is a simplified model for determining kinetic parameters for complex reactions, which assumes a set of irreversible first-order reactions that have different activation energies, and it

Restricted access

powder design. It is known that the melting rate increases with increasing carbon reactivity [ 7 ]. The reactivity of powder can be determined by knowing the decomposition kinetic of carbonaceous material; in this way, lower activation energy should be

Restricted access

important step in the kinetic analysis is the knowledge of the dependence of activation energy, E , versus the conversion degree, α . This allows the detection of multi-step processes and some conclusions on the reaction mechanism. (i

crystallization kinetics. The TMA curves shown in Fig. 4 resemble typical integral non-isothermal crystallization curves obtained from DSC data. This suggests the possibility to evaluate activation energy of crystallization from the shift of characteristic

literature [ 20 ] were used to estimate activation energy, conversion rates, and degradation time as a function of temperature. Oil produced in the pyrolysis of sunflower bagasse was characterized in a fixed-bed reactor [ 21 ]. The effects of particle

chemical decomposition reactions. It was initially developed for differential thermal analysis (DTA) data and based on the Arrhenius equation: 1 where A is the pre-exponential factor, E is the activation energy, R is universal gas constant (8.314 J

For the determination of the activation energy using multiple heating rates the isoconversional methods are used. Since every isoconversional method has different errors, the use of more than one method can give a range of values for the activation
