Rational approximations have been derived for the integral of the Arrhenius function
$$\int\limits_0^T {\exp ( - E/RT)}$$
dT which is important in the kinetic analysis of thermogravimetric data. The first degree rational approximation is found to be equivalent to the Gorbachev approximation, i.e., RT2
exp (−E/RT)/(E+2RT). The second degree rational approximation is more accurate than the Zsako empirical approximation when E/RT 5. The third and higher degree rational approximations are found to be more accurate than any other previous approximation.read more

Thermogravimetry. Fast methods for evaluation of kinetic parameters
TL;DR: In this article, the authors discuss three fast methods for determination of the reaction order, as follows: the single point method proposed by Kissinger, Horowitz and Metzger, an original two-point method, and the three point method suggested by a Gorbachev's paper.

Research on the pyrolysis kinetics of resin powder on waste printed circuit board with different particle sizes at different heating rates: inspiration for the pyrolysis mechanism
TL;DR: In this article, the pyrolysis of waste printed circuit board (PCB) resin powder can be divided into four stages: evaporation of residual water on the surface or dissipation of other small molecules, oxidation of side chain groups of epoxy resin, decomposition of tetrabromobisphenol A and decomposition residues.

Empirical formula for the exponential integral in non-isothermal kinetics
TL;DR: The exponential integral of the exponential integral can be approximated by means of the empirical formula, e.g. as mentioned in this paper, which approximates p(x) = - \int\limits_\infty ^x {\frac{{e^{ - u} }}{{u^2 }}} \cdot du\).

TL;DR: In this paper, the relationship between chemical kinetics and differential thermal analysis (DTA) curves is studied for the reactions which follow the general rate expression: r = r/sub 0/e/sup -E/RT/(1 - x).
